+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published
+    by the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<https://www.gnu.org/licenses/>.

+SimpleX Chat security audit was performed in October 2022 by [Trail of Bits](https://www.trailofbits.com/about), and most fixes were released in v4.2.0 – see [the announcement](./blog/20221108-simplex-chat-v4.2-security-audit-new-website.md).
+
+### Information you provide
+
+We do not store user profiles. The profile you create in the app is local to your device. When you create a user profile, no records are created on our servers, and we have no access to any part of your profile information, and even to the fact that you created a profile - it is a local record stored only on your device. That means that if you delete the app, and have no backup, you will permanently lose all the data and the private connections you create with other users.
+
+Messages. SimpleX Chat cannot decrypt or otherwise access the content or even size of your messages (each message is padded to a fixed size of 16kb). SimpleX Chat temporarily stores end-to-end encrypted messages on its servers for delivery to the devices that are offline, these messages are permanently removed as soon as they are delivered. Your message history is stored only on your own devices.
+
+Connections with other users. When you create a connection with another user, two messaging queues (you can think about them as about mailboxes) are created on our servers, or on the servers that you configured in the app, in case it allows such configuration (SimpleX uses separate queues for direct and response messages, that the client applications prefer to create on two different servers, in case you have more than one server configured in the app, which is the default). At the time of updating this document all our client applications allow configuring the servers. Our servers do not store information about which queues are linked to your profile on the device, and they do not collect any information that would allow us to establish that these queues are related to your device or your profile - the access to each queue is authorized by a set of anonymous unique cryptographic keys, different for each queue, and separate for sender and recipient of the messages. The exception to that is when you choose to use instant push notifications in our iOS app, because the design of push notifications requires storing the device token on notification server, and the server can observe how many messaging queues your device uses, and approximate how many messages are sent to each queue. It does not allow though to determine the actual addresses of these queues, as a separate address is used to subscibe to the notifications (unless notification and messaging servers exchange information), and who, or even how many contacts, send messages to you, as notifications are delivered to your device end-to-end encrypted by the messaging servers. It also does not allow to see message content or sizes, as the actual messages are not sent via the notification service, only the fact that the message is available and where it can be received from (the latter information is encrypted, so that the notification server cannot see it). You can read more about the design of iOS push notifications [here](https://simplex.chat/blog/20220404-simplex-chat-instant-notifications.html#our-ios-approach-has-one-trade-off).
+
+Additional technical information can be stored on our servers, including randomly generated authentication tokens, keys, push tokens, and other material that is necessary to transmit messages. SimpleX Chat limits this additional technical information to the minimum required to operate the Services.
+
+User Support. If you contact SimpleX Chat any personal data you may share with us is kept only for the purposes of researching the issue and contacting you about your case. We recommend contacting support [via chat](https://simplex.chat/contact#/?v=1&smp=smp%3A%2F%2FPQUV2eL0t7OStZOoAsPEV2QYWt4-xilbakvGUGOItUo%3D%40smp6.simplex.im%2FK1rslx-m5bpXVIdMZg9NLUZ_8JBm8xTt%23%2F%3Fv%3D1%26dh%3DMCowBQYDK2VuAyEALDeVe-sG8mRY22LsXlPgiwTNs9dbiLrNuA7f3ZMAJ2w%253D%26srv%3Dbylepyau3ty4czmn77q4fglvperknl4bi2eb2fdy2bh4jxtf32kf73yd.onion), when it is possible.
+
+### Information we may share
+
+We operate our Services using third parties. While we do not share any user data, these third party may access the encrypted user data as it is stored or transmitted via our servers.
+
+We use Third party to provide email services - if you ask for support via email, your and SimpleX Chat email providers may access these emails according their privacy policies and terms of service.
+
+The cases when SimpleX Chat may need to share the data we temporarily store on the servers:
+
+- To meet any applicable law, regulation, legal process or enforceable governmental request.
+- To enforce applicable Terms, including investigation of potential violations.
+- To detect, prevent, or otherwise address fraud, security, or technical issues.
+- To protect against harm to the rights, property, or safety of SimpleX Chat, our users, or the public as required or permitted by law.
+
+At the time of updating this document, we have never provided or have been requested the access to our servers or any information from our servers by any third parties. If we are ever requested to provide such access or information, we will follow the due legal process.
+
+### Updates
+
+We will update this privacy policy as needed so that it is current, accurate, and as clear as possible. Your continued use of our Services confirms your acceptance of our updated Privacy Policy.
+
+Please also read our Terms of Service.
+
+If you have questions about our Privacy Policy please contact us at chat@simplex.chat.
+
+## Terms of Service
+
+You accept to our Terms of Service ("Terms") by installing or using any of our apps or services ("Services").
+
+**Minimal age**. You must be at least 13 years old to use our Services. The minimum age to use our Services without parental approval may be higher in your country.
+
+**Accessing the servers**. For the efficiency of the network access, the apps access all queues you create on any server via the same network (TCP/IP) connection. Our servers do not collect information about which queues were accessed via the same connection, so we do cannot establish which queues belong to the same users. Whoever might observe your network traffic would know which servers you use, and how much data you send, but not to whom it is sent - the data that leaves the servers is always different from the data they receive - there are no identifiers or cyphertext in common. Please refer to our [technical design document](https://github.com/simplex-chat/simplexmq/blob/master/protocol/overview-tjr.md) for more information about our privacy model and known security and privacy risks.
+
+**Privacy of user data**. We do not retain any data we transmit for any longer than necessary to provide the Services. We only collect aggregate statistics across all users, not per user - we do not have information about how many people use SimpleX Chat (we only know an approximate number of app installations and the aggregate traffic through our servers). In any case, we do not and will not sell or in any way monetize user data.
+
+**Operating our services**. For the purpose of operating our Services, you agree that your end-to-end encrypted messages are transferred via our servers in the United Kingdom, the United States and other countries where we have or use facilities and service providers or partners.
+
+**Software**. You agree to downloading and installing updates to our Services when they are available; they would only be automatic if you configure your devices in this way.
+
+**Traffic and device costs**. You are solely responsible for the traffic and device costs on which you use our Services, and any associated taxes.
+
+**Legal and acceptable usage**. You agree to use our Services only for legal and acceptable purposes. You will not use (or assist others in using) our Services in ways that: 1) violate or infringe the rights of SimpleX Chat, our users, or others, including privacy, publicity, intellectual property, or other proprietary rights; 2) involve sending illegal or impermissible communications, e.g. spam.
+
+**Damage to SimpleX Chat**. You must not (or assist others to) access, use, modify, distribute, transfer, or exploit our Services in unauthorized manners, or in ways that harm SimpleX Chat, our Services, or systems. For example, you must not 1) access our Services or systems without authorization, other than by using the apps; 2) disrupt the integrity or performance of our Services; 3) collect information about our users in any manner; or 4) sell, rent, or charge for our Services.
+
+**Keeping your data secure**. SimpleX Chat is the first messaging platform that is 100% private by design - we neither have ability to access your messages, nor we have information about who you communicate with. That means that you are solely responsible for keeping your device and your user profile safe and secure. If you lose your phone or remove the app, you will not be able to recover the lost data, unless you made a back up.
+
+**Storing the messages on the device**. Currently the messages are stored in the database on your device without encryption. It means that if you make a backup of the app and store it unecrypted, the backup provider may be able to access the messages.
+
+**No Access to Emergency Services**. Our Services do not provide access to emergency service providers like the police, fire department, hospitals, or other public safety organizations. Make sure you can contact emergency service providers through a mobile, fixed-line telephone, or other service.
+
+**Third-party services**. Our Services may allow you to access, use, or interact with third-party websites, apps, content, and other products and services. When you use third-party services, their terms and privacy policies govern your use of those services.
+
+**Your Rights**. You own the mesasges and information you transmit through our Services. Your recipients are able to retain the messages you receive from you; there is no technical ability to delete data from their devices.
+
+**License**. SimpleX Chat grants you a limited, revocable, non-exclusive, and non-transferable license to use our Services in accordance with these Terms.

+## Why privacy matters
+
+Everyone should care about privacy and security of their communications - innocuous conversations can put you in danger even if there is nothing to hide.
+
+One of the most shocking stories is the experience of [Mohamedou Ould Salahi](https://en.wikipedia.org/wiki/Mohamedou_Ould_Slahi) that he wrote about in his memoir and that is shown in The Mauritanian movie. He was put into Guantanamo camp, without trial, and was tortured there for 15 years after a phone call to his relative in Afghanistan, under suspicion of being involved in 9/11 attacks, even though he lived in Germany for the 10 years prior to the attacks.
+
+It is not enough to use an end-to-end encrypted messenger, we all should use the messengers that protect the privacy of our personal networks - who we are connected with.
+
+## SimpleX approach to privacy and security
+
+### Complete privacy of your identity, profile, contacts and metadata
+
+**Unlike any other existing messaging platform, SimpleX has no identifiers assigned to the users** - not even random numbers. This protects the privacy of who are you communicating with, hiding it from SimpleX platform servers and from any observers. [Read more](./docs/SIMPLEX.md#full-privacy-of-your-identity-profile-contacts-and-metadata).
+
+### The best protection against spam and abuse
+
+As you have no identifier on SimpleX platform, you cannot be contacted unless you share a one-time invitation link or an optional temporary user address. [Read more](./docs/SIMPLEX.md#the-best-protection-against-spam-and-abuse).
+
+### Complete ownership, control and security of your data
+
+SimpleX stores all user data on client devices, the messages are only held temporarily on SimpleX relay servers until they are received. [Read more](./docs/SIMPLEX.md#complete-ownership-control-and-security-of-your-data).
+
+### Users own SimpleX network
+
+You can use SimpleX with your own servers and still communicate with people using the servers that are pre-configured in the apps or any other SimpleX servers. [Read more](./docs/SIMPLEX.md#users-own-simplex-network).
+
+## Frequently asked questions
+
+1. _How SimpleX can deliver messages without any user identifiers?_ See [v2 release annoucement](./blog/20220511-simplex-chat-v2-images-files.md#the-first-messaging-platform-without-user-identifiers) explaining how SimpleX works.
+
+2. _Why should I not just use Signal?_ Signal is a centralised platform that uses phone numbers to identify its users and their contacts. It means that while the content of your messages on Signal is protected with robust end-to-end encryption, there is a large amount of meta-data visible to Signal - who you talk with and when.
+
+3. _How is it different from Matrix, Session, Ricochet, Cwtch, etc., that also don't require user identites?_ Although these platforms do not require a _real identity_, they do rely on anonymous user identities to deliver messages – it can be, for example, an identity key or a random number. Using a persistent user identity, even anonymous, creates a risk that user's connection graph becomes known to the observers and/or service providers, and it can lead to de-anonymizing some users. If the same user profile is used to connect to two different people via any messenger other than SimpleX, these two people can confirm if they are connected to the same person - they would use the same user identifier in the messages. With SimpleX there is no meta-data in common between your conversations with different contacts - the quality that no other messaging platform has.

+
+## Make a private connection
+
+You need to share a link or scan a QR code (in person or during a video call) to make a connection and start messaging.
+
+The channel through which you share the link does not have to be secure - it is enough that you can confirm who sent you the message and that your SimpleX connection is established.

+
+## SimpleX Platform design
+
+SimpleX is a client-server network with a unique network topology that uses redundant, disposable message relay nodes to asynchronously pass messages via unidirectional (simplex) message queues, providing recipient and sender anonymity.
+
+Unlike P2P networks, all messages are passed through one or several server nodes, that do not even need to have persistence. In fact, the current [SMP server implementation](https://github.com/simplex-chat/simplexmq#smp-server) uses in-memory message storage, persisting only the queue records. SimpleX provides better metadata protection than P2P designs, as no global participant identifiers are used to deliver messages, and avoids [the problems of P2P networks](./docs/SIMPLEX.md#comparison-with-p2p-messaging-protocols).
+
+Unlike federated networks, the server nodes **do not have records of the users**, **do not communicate with each other** and **do not store messages** after they are delivered to the recipients. There is no way to discover the full list of servers participating in SimpleX network. This design avoids the problem of metadata visibility that all federated networks have and better protects from the network-wide attacks.
+
+Only the client devices have information about users, their contacts and groups.
+
+See [SimpleX whitepaper](https://github.com/simplex-chat/simplexmq/blob/stable/protocol/overview-tjr.md) for more information on platform objectives and technical design.
+
+See [SimpleX Chat Protocol](./docs/protocol/simplex-chat.md) for the format of messages sent between chat clients over [SimpleX Messaging Protocol](https://github.com/simplex-chat/simplexmq/blob/stable/protocol/simplex-messaging.md).
+
+## Privacy: technical details and limitations
+
+SimpleX Chat is a work in progress – we are releasing improvements as they are ready. You have to decide if the current state is good enough for your usage scenario.
+
+What is already implemented:
+
+1. Instead of user profile identifiers used by all other platforms, even the most private ones, SimpleX uses pairwise per-queue identifiers (2 addresses for each unidirectional message queue, with an optional 3rd address for push notificaitons on iOS, 2 queues in each connection between the users). It makes observing the network graph on the application level more difficult, as for `n` users there can be up to `n * (n-1)` message queues.
+2. End-to-end encryption in each message queue using [NaCl cryptobox](https://nacl.cr.yp.to/box.html). This is added to allow redundancy in the future (passing each message via several servers), to avoid having the same ciphertext in different queues (that would only be visible to the attacker if TLS is compromised). The encryption keys used for this encryption are not rotated, instead we are planning to rotate the queues. Curve25519 keys are used for key negotiation.
+3. [Double ratchet](https://signal.org/docs/specifications/doubleratchet/) end-to-end encryption in each conversation between two users (or group members). This is the same algorithm that is used in Signal and many other messaging apps; it provides OTR messaging with forward secrecy (each message is encrypted by its own ephemeral key), break-in recovery (the keys are frequently re-negotiated as part of the message exchange). Two pairs of Curve448 keys are used for the initial key agreement, initiating party passes these keys via the connection link, accepting side - in the header of the confirmation message.
+4. Additional layer of encryption using NaCL cryptobox for the messages delivered from the server to the recipient. This layer avoids having any ciphertext in common between sent and received traffic of the server inside TLS (and there are no identifiers in common as well).
+5. Several levels of content padding to frustrate message size attacks.
+6. Starting from v2 of SMP protocol (the current version is v4) all message metadata, including the time when the message was received by the server (rounded to a second) is sent to the recipients inside an encrypted envelope, so even if TLS is compromised it cannot be observed.
+7. Only TLS 1.2/1.3 are allowed for client-server connections, limited to cryptographic algorithms: CHACHA20POLY1305_SHA256, Ed25519/Ed448, Curve25519/Curve448.
+8. To protect against replay attacks SimpleX servers require [tlsunique channel binding](https://www.rfc-editor.org/rfc/rfc5929.html) as session ID in each client command signed with per-queue ephemeral key.
+9. To protect your IP address all SimpleX Chat clients support accessing messaging servers via Tor - see [v3.1 release announcement](./blog/20220808-simplex-chat-v3.1-chat-groups.md) for more details.
+10. Local database encryption with passphrase - your contacts, groups and all sent and received messages are stored encrypted. If you used SimpleX Chat before v4.0 you need to enable the encryption via the app settings.
+
+We plan to add soon:
+
+1. Message queue rotation. Currently the queues created between two users are used until the contact is deleted, providing a long-term pairwise identifiers of the conversation. We are planning to add queue rotation to make these identifiers temporary and rotate based on some schedule TBC (e.g., every X messages, or every X hours/days).
+2. Local files encryption. Currently the images and files you send and receive are stored in the app unencrypted, you can delete them via `Settings / Database passphrase & export`.
+3. Message "mixing" - adding latency to message delivery, to protect against traffic correlation by message time.
+
+## For developers
+
+You can:
+
+- use SimpleX Chat library to integrate chat functionality into your mobile apps.
+- create chat bots and services in Haskell - see [simple](./apps/simplex-bot/) and more [advanced chat bot example](./apps/simplex-bot-advanced/).
+- create chat bots and services in any language running SimpleX Chat terminal CLI as a local WebSocket server. See [TypeScript SimpleX Chat client](./packages/simplex-chat-client/) and [JavaScipt chat bot example](./packages/simplex-chat-client/typescript/examples/squaring-bot.js).
+- run [simplex-chat terminal CLI](./docs/CLI.md) to execute individual chat commands, e.g. to send messages as part of shell script execution.
+
+If you are considering developing with SimpleX platform please get in touch for any advice and support.
+
+## Roadmap
+
+- ✅ Easy to deploy SimpleX server with in-memory message storage, without any dependencies.
+- ✅ Terminal (console) client with groups and files support.
+- ✅ One-click SimpleX server deployment on Linode.
+- ✅ End-to-end encryption using double-ratchet protocol with additional encryption layer.
+- ✅ Mobile apps v1 for Android and iOS.

+- ✅ Manual chat history deletion.
+- ✅ End-to-end encrypted WebRTC audio and video calls via the mobile apps.
+- ✅ Privacy preserving instant notifications for iOS using Apple Push Notification service.
+- ✅ Chat database export and import.
+- ✅ Chat groups in mobile apps.
+- ✅ Connecting to messaging servers via Tor.
+- ✅ Dual server addresses to access messaging servers as v3 hidden services.
+- ✅ Chat server and TypeScript client SDK to develop chat interfaces, integrations and chat bots (ready for announcement).
+- ✅ Incognito mode to share a new random name with each contact.
+- ✅ Chat database encryption.
+- ✅ Automatic chat history deletion.
+- ✅ Links to join groups and improve groups stability.
+- ✅ Voice messages (with recipient opt-out per contact).
+- ✅ Basic authentication for SMP servers (to authorize creating new queues).
+- ✅ View deleted messages, full message deletion by sender (with recipient opt-in per contact).
+- ✅ Block screenshots and view in recent apps.
+- ✅ Advanced server configuration.
+- ✅ Disappearing messages (with recipient opt-in per-contact).
+- ✅ "Live" messages.
+- ✅ Contact verification via a separate out-of-band channel.
+- 🏗 Multiple user profiles in the same chat database.
+- 🏗 Optionally avoid re-using the same TCP session for multiple connections.
+- 🏗 File server to optimize for efficient and private sending of large files.
+- 🏗 SMP queue redundancy and rotation (manual is supported).
+- 🏗 Reduced battery and traffic usage in large groups.
+- 🏗 Preserve message drafts.
+- 🏗 Support older Android OS and 32-bit CPUs.
+- Ephemeral/disappearing/OTR conversations with the existing contacts.
+- Access password/pin (with optional alternative access password).
+- Video messages.
+- Message delivery confirmation (with sender opt-in or opt-out per contact, TBC).
+- Feeds/broadcasts.
+- Web widgets for custom interactivity in the chats.
+- Programmable chat automations / rules (automatic replies/forward/deletion/sending, reminders, etc.).
+- Supporting the same profile on multiple devices.
+- Desktop client.
+- Privacy-preserving identity server for optional DNS-based contact/group addresses to simplify connection and discovery, but not used to deliver messages:
+  - keep all your contacts and groups even if you lose the domain.
+  - the server doesn't have information about your contacts and groups.
+- Channels server for large groups and broadcast channels.
+

+
+## Disclaimers
+
+[SimpleX protocols and security model](https://github.com/simplex-chat/simplexmq/blob/master/protocol/overview-tjr.md) was reviewed, and had many breaking changes and improvements in v1.0.0.
+
+The security audit was performed in October 2022 by [Trail of Bits](https://www.trailofbits.com/about), and most fixes were released in v4.2.0 – see [the announcement](./blog/20221108-simplex-chat-v4.2-security-audit-new-website.md).
+
+SimpleX Chat is still a relatively early stage platform (the mobile apps were released in March 2022), so you may discover some bugs and missing features. We would really appreciate if you let us know anything that needs to be fixed or improved.
+
+The default servers configured in the app are provided on the best effort basis. We are currently not guaranteeing any SLAs, although historically our servers had over 99.9% uptime each.
+
+We have never provided or have been requested access to our servers or any information from our servers by any third parties. If we are ever requested to provide such access or information, we will be following due legal process.
+
+We do not log IP addresses of the users and we do not perform any traffic correlation on our servers. If transport level security is critical you must use Tor or some other similar network to access messaging servers. We will be improving the client applications to reduce the opportunities for traffic correlation.
+
+Please read more in [Terms & privacy policy](./PRIVACY.md).
+
+## Security contact
+
+To report a security vulnerability, please send us email to chat@simplex.chat. We will coordinate the fix and disclosure. Please do NOT report security vulnerabilities via GitHub issues.
+
+Please treat any findings of possible traffic correlation attacks allowing to correlate two different conversations to the same user, other than covered in [the threat model](https://github.com/simplex-chat/simplexmq/blob/stable/protocol/overview-tjr.md#threat-model), as security vulnerabilities, and follow this disclosure process.
