+SimpleX Chat security assessment was done in October 2022 by [Trail of Bits](https://www.trailofbits.com/about), and most fixes were released in v4.2.0 – 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.
+#### User profiles
 
-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.
+We do not store user profiles. The profile you create in the app is local to your device.
 
-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).
+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 and Files
+
+SimpleX Chat 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 256kb, 1mb or 8mb via all or some of the configured file 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 SimpleX Chat temporarily stores end-to-end encrypted messages on the messaging (SMP) servers that are preset in the app or chosen by the users.
+
+The messages are permanently removed from the preset servers as soon as they are delivered. Undelivered messages are deleted after the time that is configured in the messaging servers you use (21 days for preset messaging servers).
+
+The files are stored on file (XFTP) servers for the time configured in the file servers you use (48 hours for preset file servers).
+
+If a messaging or file servers are restarted, the encrypted message or the record of the file can be stored in a backup file until it is overwritten by the next restart (usually within 1 week).
+
+#### 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 chosen messaging servers, that can be the preset servers or 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.

+
+#### iOS Push Notifications
+
+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.
+
+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, 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 server, 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 observe 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).
+
+#### 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 limits this additional technical information to the minimum required to operate the Services.

@@ -266,18 +289,23 @@ What is already implemented:
 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. 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.
+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, except videos (to be added later).
 
-We plan to add soon:
+We plan to add:
 
-1. Automatic message queue rotation. 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).
-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.
+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.
