+## Introduction
+
+SimpleX Chat (also referred to as SimpleX) is the first communication network based on a new protocol stack that builds on the same ideas of complete openness and decentralization as email and web, with the focus on providing security and privacy of communications, and without compromising on usability.
+
+SimpleX messaging protocol is the first protocol that has no user profile IDs of any kind, not even random numbers, cryptographic keys or hashes that identify the users. SimpleX apps allow their users to send messages and files via relay server infrastructure. Relay server owners and operators do not have any access to your messages, thanks to double-ratchet end-to-end encryption algorithm (also known as Signal algorithm - do not confuse with Signal protocols or platform) and additional encryption layers, and they also have no access to your profile and contacts - as they do not host user accounts.
 
 Double ratchet algorithm has such important properties as [forward secrecy](/docs/GLOSSARY.md#forward-secrecy), sender [repudiation](/docs/GLOSSARY.md#) and break-in recovery (also known as [post-compromise security](/docs/GLOSSARY.md#post-compromise-security)).

 ## Privacy Policy
 
-SimpleX Chat Ltd uses the best industry practices for security and encryption to provide client and server software for secure [end-to-end encrypted](/docs/GLOSSARY.md#end-to-end-encryption) messaging via private connections. This encryption cannot be compromised by the relays servers, even if they are modified or compromised, via [man-in-the-middle attack](/docs/GLOSSARY.md#man-in-the-middle-attack), unlike most other communication platforms, services and networks.
+### General principles
 
-SimpleX Chat software is built on top of SimpleX messaging and application protocols, based on a new message routing protocol allowing to establish private connections without having any kind of addresses or other identifiers assigned to its users - it does not use emails, phone numbers, usernames, identity keys or any other user profile identifiers to pass messages between the user applications.
+SimpleX network software uses the best industry practices for security and encryption to provide client and server software for secure [end-to-end encrypted](/docs/GLOSSARY.md#end-to-end-encryption) messaging via private connections. This encryption is protected from being compromised by the relays servers, even if they are modified or compromised, via [man-in-the-middle attack](/docs/GLOSSARY.md#man-in-the-middle-attack).
 
-SimpleX Chat software is similar in its design approach to email clients and browsers - it allows you to have full control of your data and freely choose the relay server providers, in the same way you choose which website or email provider to use, or use your own relay servers, simply by changing the configuration of the client software. The only current restriction to that is Apple push notifications - at the moment they can only be delivered via the preset servers that we operate, as explained below. We are exploring the solutions to deliver push notifications to iOS devices via other providers or users' own servers.

-While SimpleX Chat Ltd is not a communication service provider, and provide public preset relays "as is", as experimental, without any guarantees of availability or data retention, we are committed to maintain a high level of availability, reliability and security of these preset relays. We will be adding alternative preset infrastructure providers to the software in the future, and you will continue to be able to use any other providers or your own servers.

We are exploring the solutions to deliver push notifications to iOS devices via other providers or users' own servers.
 
-We see users and data sovereignty, and device and provider portability as critically important properties for any communication system.
+SimpleX network operators are not communication service provider, and provide public relays "as is", as experimental, without any guarantees of availability or data retention. The operators of the relay servers preset in the app ("Preset Server Operators"), including SimpleX Chat Ltd, are committed to maintain a high level of availability, reliability and security. SimpleX client apps can have multiple preset relay server operators that you can opt-in or opt-out of using. You are and will continue to be able to use any other operators or your own servers.
 
-SimpleX Chat security assessment was done in October 2022 by [Trail of Bits](https://www.trailofbits.com/about), and most fixes were released in v4.2 – see [the announcement](/blog/20221108-simplex-chat-v4.2-security-audit-new-website.md).

 ### Your information
 
 #### User profiles
 
-Servers used by SimpleX Chat apps do not create, store or identify user profiles. The profiles you can create in the app are local to your device, and can be removed at any time via the app.
+Servers used by SimpleX Chat apps do not create, store or identify user chat profiles. The profiles you can create in the app are local to your device, and can be removed at any time via the app.
 
-When you create the local profile, no records are created on any of the relay servers, and infrastructure providers, whether SimpleX Chat Ltd or any other, have no access to any part of your 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 your data and the private connections you created with other software users.
+When you create the local profile, no records are created on any of the relay servers, and infrastructure operators, whether preset in the app or any other, have no access to any part of your 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 your data and the private connections you created with other software users.
 
 You can transfer the profile to another device by creating a backup of the app data and restoring it on the new device, but you cannot use more than one device with the copy of the same profile at the same time - it will disrupt any active conversations on either or both devices, as a security property of end-to-end encryption.
 
 #### Messages and Files
 
-SimpleX relay servers cannot decrypt or otherwise access the content or even the size of your messages and files you send or receive. Each message is padded to a fixed size of 16kb. Each file is sent in chunks of 64kb, 256kb, 1mb or 8mb via all or some of the configured file relay servers. Both messages and files are sent end-to-end encrypted, and the servers do not have technical means to compromise this encryption, because part of the [key exchange](/docs/GLOSSARY.md#key-exchange) happens out-of-band.
+SimpleX relay servers cannot decrypt or otherwise access the content or even the size of your messages and files you send or receive. Each message is padded to a fixed size of 16kb. Each file is sent in chunks of 64kb, 256kb, 1mb or 4mb via all or some of the configured file relay servers. Both messages and files are sent end-to-end encrypted, and the servers do not have technical means to compromise this encryption, because part of the [key exchange](/docs/GLOSSARY.md#key-exchange) happens out-of-band.
 
 Your message history is stored only on your own device and the devices of your contacts. While the recipients' devices are offline, messaging relay servers temporarily store end-to-end encrypted messages – you can configure which relay servers are used to receive the messages from the new contacts, and you can manually change them for the existing contacts too.
 
-You do not have control over which servers are used to send messages to your contacts - they are chosen by them. To send messages your client needs to connect to these servers, therefore the servers chosen by your contacts can observe your IP address. You can use VPN or some overlay network (e.g., Tor) to hide your IP address from the servers chosen by your contacts. In the near future we will add the layer in the messaging protocol that will route sent message via the relays chosen by you as well.
+#### Private message delivery 
 
-The messages are permanently removed from the used relay servers as soon as they are delivered, as long as these servers used unmodified published code. Undelivered messages are deleted after the time that is configured in the messaging servers you use (21 days for preset messaging servers).
+You do not have control over which servers are used to send messages to your contacts - these servers are chosen by your contacts. To send messages your client by default uses configured servers to forward messages to the destination servers, thus protecting your IP address from the servers chosen by your contacts.
+
+In case you use preset servers of more than one operator, the app will prefer to use a server of an operator different from the operator of the destination server to forward messages, preventing destination server to correlate messages as belonging to one client.
+
+You can additionally use VPN or some overlay network (e.g., Tor) to hide your IP address from the servers chosen by you.
+
+*Please note*: the clients allow changing configuration to connect to the destination servers directly. It is not recommended - if you make such change, your IP address will be visible to the destination servers.
+
+#### Storage of messages and files on the servers
+
+The messages are removed from the relay servers as soon as all messages of the file they were stored in are delivered and saving new messages switches to another file, as long as these servers use unmodified published code. Undelivered messages are also marked as delivered after the time that is configured in the messaging servers you use (21 days for preset messaging servers).
 
 The files are stored on file relay servers for the time configured in the relay servers you use (48 hours for preset file servers).
 
-If a messaging servers are restarted, the encrypted message can be stored in a backup file until it is overwritten by the next restart (usually within 1 week for preset relay servers).
-
-As this software is fully open-source and provided under AGPLv3 license, all infrastructure providers and owners, and the developers of the client and server applications who use the SimpleX Chat source code, are required to publish any changes to this software under the same AGPLv3 license - including any modifications to the provided servers.
-
-In addition to the AGPLv3 license terms, SimpleX Chat Ltd is committed to the software users that the preset relays that we provide via the apps will always be compiled from the [published open-source code](https://github.com/simplex-chat/simplexmq), without any modifications.
+The encrypted messages can be stored for some time after they are delivered or expired (because servers use append-only logs for message storage). This time varies, and may be longer in connections with fewer messages, but it is usually limited to 1 month, including any backup storage.
 
 #### Connections with other users
 
-When you create a connection with another user, two messaging queues (you can think about them as mailboxes) are created on messaging relay servers (chosen by you and your contact each), that can be the preset servers or the servers that you and your contact configured in the app. SimpleX messaging protocol uses separate queues for direct and response messages, and the apps prefer to create these queues on two different relay servers for increased privacy, in case you have more than one relay server configured in the app, which is the default.

-SimpleX relay 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 infrastructure owners and providers to establish that these queues are related to your device or your profile - the access to each queue is authorized by two anonymous unique cryptographic keys, different for each queue, and separate for sender and recipient of the messages.

 #### iOS Push Notifications
 
+This section applies only to the notification servers operated by SimpleX Chat Ltd.
+
 When you choose to use instant push notifications in SimpleX iOS app, because the design of push notifications requires storing the device token on notification server, the notifications server can observe how many messaging queues your device has notifications enabled for, and approximately how many messages are sent to each queue.
 
 Preset notification server cannot observe the actual addresses of these queues, as a separate address is used to subscribe to the notifications. It also cannot observe who sends messages to you. Apple push notifications servers can only observe how many notifications are sent to you, but not from how many contacts, or from which messaging relays, as notifications are delivered to your device end-to-end encrypted by one of the preset notification servers - these notifications only contain end-to-end encrypted metadata, not even encrypted message content, and they look completely random to Apple push notification servers.

 #### Another information stored on the servers
 
-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 design limits this additional technical information to the minimum required to operate the software and servers. To prevent server overloading or attacks, the servers can temporarily store data that can link to particular users or devices, including IP addresses, geographic location, or information related to the transport sessions. This information is not stored for the absolute majority of the app users, even for those who use the servers very actively.

-SimpleX Chat Ltd operates preset relay servers using third parties. While we do not have access and cannot share any user data, these third parties may access the encrypted user messages (but NOT the actual unencrypted message content or size) as it is stored or transmitted via our servers. Hosting providers can also store IP addresses and other transport information as part of their logs.
+Preset server operators will not share the information on their servers with each other, other than aggregate usage statistics. 
 
-We use a third party for email services - if you ask for support via email, your and SimpleX Chat Ltd email providers may access these emails according to their privacy policies and terms. When the request is sensitive, we recommend contacting us via SimpleX Chat or using encrypted email using PGP key published at [openpgp.org](https://keys.openpgp.org/search?q=chat%40simplex.chat).
+Preset server operators will not provide general access to their servers or the data on their servers to each other.
 
-The cases when SimpleX Chat Ltd may share the data temporarily stored on the servers:
+Preset server operators will provide non-administrative access to control port of preset servers to SimpleX Chat Ltd, for the purposes of removing identified illegal content. This control port access only allows deleting known links and files, and access to aggregate statistics, but does NOT allow enumerating any information on the servers.

Our infrastructure does not have any modifications from the [published open-source code](https://github.com/simplex-chat/simplexmq) available under AGPLv3 license. Any infrastructure provider, whether commercial or not, is required by the Affero clause (named after Affero Inc. company that pioneered the community-based Q&A sites in early 2000s) to publish any modifications under the same license.

If you ever discover any tracking or analytics code, please report it to SimpleX Chat Ltd, so it can be removed.
 
-**Accessing the infrastructure**. For the efficiency of the network access, the client Software by default accesses all queues your app creates on any relay server within one user profile via the same network (TCP/IP) connection. At the cost of additional traffic this configuration can be changed to use different transport session for each connection. Relay servers do not collect information about which queues were created or accessed via the same connection, so the relay servers cannot establish which queues belong to the same user profile. Whoever might observe your network traffic would know which relay 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 ciphertext in common, even inside TLS encryption layer. 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**. Servers do not retain any data we transmit for any longer than necessary to deliver the messages between apps. SimpleX Chat Ltd collects aggregate statistics across all its servers, as supported by published code and can be enabled by any infrastructure provider, but not any statistics per-user, or per geographic location, or per IP address, or per transport session. We do not have information about how many people use SimpleX Chat applications, we only know an approximate number of app installations and the aggregate traffic through the preset servers. In any case, we do not and will not sell or in any way monetize user data. Our future business model assumes charging for some optional Software features instead, in a transparent and fair way.

-**Keeping your data secure**. SimpleX Chat is the first communication software that aims to be 100% private by design - server software neither has the ability to access your messages, nor it has information about who you communicate with. That means that you are solely responsible for keeping your device, your user profile and any data safe and secure. If you lose your phone or remove the Software from the device, you will not be able to recover the lost data, unless you made a back up. To protect the data you need to make regular backups, as using old backups may disrupt your communication with some of the contacts.

To protect the data you need to make regular backups, as using old backups may disrupt your communication with some of the contacts. SimpleX Chat Ltd and other preset server operators are not responsible for any data loss.
 
 **Storing the messages on the device**. The messages are stored in the encrypted database on your device. Whether and how database passphrase is stored is determined by the configuration of the Software you use. The databases created prior to 2023 or in CLI (terminal) app may remain unencrypted, and it will be indicated in the app interface. In this case, if you make a backup of the data and store it unencrypted, the backup provider may be able to access the messages. Please note, that the desktop apps can be configured to store the database passphrase in the configuration file in plaintext, and unless you set the passphrase when first running the app, a random passphrase will be used and stored on the device. You can remove it from the device via the app settings.
 
 **Storing the files on the device**. The files currently sent and received in the apps by default (except CLI app) are stored on your device encrypted using unique keys, different for each file, that are stored in the database. Once the message that the file was attached to is removed, even if the copy of the encrypted file is retained, it should be impossible to recover the key allowing to decrypt the file. This local file encryption may affect app performance, and it can be disabled via the app settings. This change will only affect the new files. If you later re-enable the encryption, it will also affect only the new files. If you make a backup of the app data and store it unencrypted, the backup provider will be able to access any unencrypted files. In any case, irrespective of the storage setting, the files are always sent by all apps end-to-end encrypted.
 
-**No Access to Emergency Services**. Our Applications 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.

-**Your Rights**. You own the messages and the information you transmit through our Applications. Your recipients are able to retain the messages they receive from you; there is no technical ability to delete data from their devices. While there are various app features that allow deleting messages from the recipients' devices, such as _disappearing messages_ and _full message deletion_, their functioning on your recipients' devices cannot be guaranteed or enforced, as the device may be offline or have a modified version of the Software. At the same time, repudiation property of the end-to-end encryption algorithm allows you to plausibly deny having sent the message, like you can deny what you said in a private face-to-face conversation, as the recipient cannot provide any proof to the third parties, by design.
