 ## Privacy Policy
 
 SimpleX Chat Ltd. ("SimpleX Chat") uses the best industry practices for security and end-to-end encryption to provide secure end-to-end encrypted messaging via private connections. SimpleX Chat is built on top of SimpleX messaging and application platform that uses a new message routing protocol that allows establishing private connection without having any kind of addresses that identify its users - we don't use emails, phone numbers, usernames, identity keys or any other user identifiers to pass messages between the users.
 
+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 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 temporarily offline. Your message history is stored only on your own devices.
+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 are created on our servers (we use separate queues for direct and response messages, that can be on two different servers), or on the servers that you configured in the app, in case it allows such configuration. At the time of updating this document only our terminal app allows configuring the servers, our mobile apps will allow such configuration in the near future. Our servers do not store information about which queues are linked to your profile on the device, and they do not have any information in common that 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 unique encryption keys, different for each queue, and separate for sender and recipient of the messages that are transmitted through the queue.
+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.

+
+## Join user groups
+
+**Please note**: The groups below are created for the users to be able to ask questions, make suggestions and ask questions about SimpleX Chat only.
+
+You also can:
+- criticize the app, and make comparisons with other messengers.
+- share new messengers you think could be interesting for privacy, as long as you don't spam.
+- share some privacy related publications, infrequently.
+- having preliminary approved with the admin in direct message, share the link to a group you created.
+
+You must:
+- be polite to other users
+- avoid spam (too frequent messages, even if they are relevant)
+- avoid any personal attacks or hostility.
+- avoid sharing any content that is not relevant to the above (that includes, but is not limited to, discussing politics or any aspects of society other than privacy, security, technology and communications, sharing any content that may be found offensive by other users, etc.).
+
+Messages not following these rules will be deleted, the right to send messages may be revoked, and the access to the new members to the group may be temporarily restricted, to prevent re-joining under a different name - our imperfect group moderation does not have a better solution at the moment.
+
+You can join an English-speaking users group if you want to ask any questions: [#SimpleX-Group-4](https://simplex.chat/contact#/?v=1-2&smp=smp%3A%2F%2Fu2dS9sG8nMNURyZwqASV4yROM28Er0luVTx5X1CsMrU%3D%40smp4.simplex.im%2Fw2GlucRXtRVgYnbt_9ZP-kmt76DekxxS%23%2F%3Fv%3D1-2%26dh%3DMCowBQYDK2VuAyEA0tJhTyMGUxznwmjb7aT24P1I1Wry_iURTuhOFlMb1Eo%253D%26srv%3Do5vmywmrnaxalvz6wi3zicyftgio6psuvyniis6gco6bp6ekl4cqj4id.onion&data=%7B%22type%22%3A%22group%22%2C%22groupLinkId%22%3A%22WoPxjFqGEDlVazECOSi2dg%3D%3D%22%7D)

+You can join either by opening these links in the app or by opening them in a desktop browser and scanning the QR code.
+
+## Make a private connection
+
+You need to share a link with your friend or scan a QR code from their phone, 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.

 ## 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 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.
 
+We compiled a [glossary of terms](./docs/GLOSSARY.md) used to describe communication systems to help understand some terms below and to help compare advantages and disadvantages of various communication systems.
+
 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.
+1.

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.

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 to frustrate message size attacks.
+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.
 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.
 
 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 termporary and rotate based on some schedule TBC (e.g., every X messages, or every X hours/days).
-2. Local database encryption. Currently the local chat database stored on your device is not encrypted.
+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.
-4. Independent implementation audit.

-## Help us pay for 3rd party security audit
+## Disclaimers
 
-I will get straight to the point: I ask you to support SimpleX Chat with donations.
+[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.
 
-We are prioritizing users privacy and security - it would be impossible without your support we were lucky to have so far.
+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).
 
-We are planning a 3rd party security audit for the app, and it would hugely help us if some part of this $20,000+ expense could be covered with donations.
+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.
 
-Our pledge to our users is that SimpleX protocols are and will remain open, and in public domain, - so anybody can build the future implementations of the clients and the servers. We are building SimpleX platform based on the same principles as email and web, but much more private and secure.
+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.
 
-If you are already using SimpleX Chat, or plan to use it in the future when it has more features, please consider making a donation - it will help us to raise more funds. Donating any amount, even the price of the cup of coffee, would make a huge difference for us.
+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.
 
-It is possible to donate via:
+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.

+
+2. Set weight to 400, grade to -25 and size to 48px.
+
+3. Click on the icon, choose Android and download XML file.
+
+4. Update the color to black (#FF000000) and the size to "24.dp", as in other icons.
