+## 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.

-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.

+#### Public groups and content channels
+
+You may participate in a public group and receive content from a public channel (Group). In case you send messages or comments to the Group, you grant a license:
+- to all recipients:
+  - to share your messages with the new Group members and outside of the group, e.g. via quoting (replying), forwarding and copy-pasting your message. When your message is deleted or marked as deleted, the copies of your message will not be deleted.
+  - to retain a copy of your messages according to the Group settings (e.g., the Group may allow irreversible message deletion from the recipient devices for a limited period of time, or it may only allow to edit and mark messages as deleted on recipient devices). Deleting message from the recipient devices or marking message as deleted revokes the license to share the message.
+- to Group owners: to share your messages with the new Group members as history of the Group. Currently, the Group history shared with the new members is limited to 100 messages.
+
+Group owners may use chat relays or automated bots (Chat Relays) to re-broadcast member messages to all members, for efficiency. The Chat Relays may be operated by the group owners, by preset operators or by 3rd parties. The Chat Relays have access to and will retain messages in line with Group settings, for technical functioning of the Group. Neither you nor group owners grant any content license to Chat Relay operators.

-**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.

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.

 ## :zap: Quick installation of a terminal app
@@ -300,25 +296,28 @@ 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](./docs/GLOSSARY.md#pairwise-pseudonymous-identifier) (2 addresses for each unidirectional message queue, with an optional 3rd address for push notifications 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](./docs/GLOSSARY.md#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](./docs/GLOSSARY.md#double-ratchet-algorithm) 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](./docs/GLOSSARY.md#forward-secrecy) (each message is encrypted by its own ephemeral key) and [break-in recovery](./docs/GLOSSARY.md#post-compromise-security) (the keys are frequently re-negotiated as part of the message exchange). Two pairs of Curve448 keys are used for the initial [key agreement](./docs/GLOSSARY.md#key-agreement-protocol), 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](./docs/GLOSSARY.md#message-padding) to frustrate message size attacks.
-6. 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.
-11. Transport isolation - different TCP connections and Tor circuits are used for traffic of different user profiles, optionally - for different contacts and group member connections.
-12. Manual messaging queue rotations to move conversation to another SMP relay.
-13. Sending end-to-end encrypted files using [XFTP protocol](https://simplex.chat/blog/20230301-simplex-file-transfer-protocol.html).
-14. Local files encryption.
+4. [Post-quantum resistant key exchange](./docs/GLOSSARY.md#post-quantum-cryptography) in double ratchet protocol *on every ratchet step*. Read more in [this post](./blog/20240314-simplex-chat-v5-6-quantum-resistance-signal-double-ratchet-algorithm.md) and also see this [publication by Apple]( https://security.apple.com/blog/imessage-pq3/) explaining the need for post-quantum key rotation.

+10. To protect your IP address from unknown messaging relays, and for per-message transport anonymity (compared with Tor/VPN per-connection anonymity), from v6.0 all SimpleX Chat clients use private message routing by default. Read more in [this post](./blog/20240604-simplex-chat-v5.8-private-message-routing-chat-themes.md#private-message-routing).
+11. To protect your IP address from unknown file relays, when SOCKS proxy is not enabled SimpleX Chat clients ask for a confirmation before downloading the files from unknown servers.
+12. To protect your IP address from known servers 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.

+17. Local files encryption.
+18. [Reproducible server builds](./docs/SERVER.md#reproduce-builds).
 
 We plan to add:
 
-1. Senders' SMP relays and recipients' XFTP relays to reduce traffic and conceal IP addresses from the relays chosen, and potentially controlled, by another party.
-2. Post-quantum resistant key exchange in double ratchet protocol.
-3. Automatic message queue rotation and redundancy. Currently the queues created between two users are used until the queue is manually changed by the user or contact is deleted. We are planning to add automatic queue rotation to make these identifiers temporary and rotate based on some schedule TBC (e.g., every X messages, or every X hours/days).
-4. Message "mixing" - adding latency to message delivery, to protect against traffic correlation by message time.
-5. Reproducible builds – this is the limitation of the development stack, but we will be investing into solving this problem. Users can still build all applications and services from the source code.
