 # SimpleX Chat Terms & Privacy Policy
 
-SimpleX Chat is the first chat platform that is 100% private by design - not only it has no access to your messages (thanks to open-source double-ratchet end-to-end encryption protocol and additional encryption layers), it also has no access to your profile and contacts - we do not have access to your connections graph.

 ## 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.

+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.

+## 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.

 Groups have been supported by SimpleX Chat core for a very long time, but there was no user interface in the mobile apps to use them - users had to use chat console to create groups, add members, and accept invitations.
 
-This release allows accepting the invitations to join groups via mobile apps UI, making it much easier to create groups - only one user (a group owner) needs to use chat console, while all other groups members just need to tap a button in the UI to join or leave the group. Full group UI is coming in v3.1 in 1-2 weeks, but you can already start using groups today by installing beta-versions of mobile apps via [TestFlight](https://testflight.apple.com/join/DWuT2LQu), [Google PlayStore Beta](https://play.google.com/apps/testing/chat.simplex.app) and [APK download](https://github.com/simplex-chat/simplex-chat/releases/download/v3.1.0-beta.0/simplex.apk).

+
+**Published:** Nov 8, 2022
+
+## Security assessment by Trail of Bits
+
+<img src="./images/20221108-trail-of-bits.jpg" width=240>
+
+When we first launched the app in March the response on Reddit was: _"Have you been audited or should we just ignore you?"_.
+
+We have a growing number of enthusiasts using SimpleX Chat who can accept the security risks of unaudited system, but the users who depend on their security were patiently waiting until some independent experts validate our claims.
+
+[Trail of Bits](https://www.trailofbits.com/about), a US based security and technology consultancy whose clients include big tech companies, governmental agencies and major blockchain projects, had 2 engineers reviewing SimpleX Chat, specifically [simplexmq library](https://github.com/simplex-chat/simplexmq) that is responsible for all cryptography and networking of SimpleX platform.
+
+2 medium and 2 low severity issues were identified, all of which require a high difficulty attack to exploit – the attacker would need to have a privileged access to the system, may need to know complex technical details, or must discover other weaknesses to exploit them. 3 of these issues are already fixed in v4.2.
+
+Overall we have SimpleX Chat in a decent shape, with most reviewed areas other than identified issues being marked as "satisfactory", and authentication and access controls as "strong".
+
+The issues are explained below, and the full security review is available via [Trail of Bits publications](https://github.com/trailofbits/publications#technology-product-reviews).
+
+We are hugely thankful to Trails Of Bits and their engineers for the work they did, helping us identify these issues and strengthen the security of SimpleX Chat.
+
+### Medium severity issues
+
+#### X3DH key exchange for double ratchet protocol
+
+We made a mistake implementing X3DH key exchange - the key derivation function was not applied to the result of concatenation of three DH operations. The attack to exploit this mistake has high complexity, as it would require compromising one of private keys generated by the clients, and also it would only affect forward secrecy until break-in recovery happens (after both sides sent some messages).
+
+Please note that SimpleX does not perform X3DH with long-term identity keys, as the SimpleX protocol does not rely on long-term keys to identify client devices. Therefore, the impact of compromising a key will be less severe, as it will affect only the secrets of the connection where the key was compromised.
+
+This issue is fixed in version 4.2 in [this PR](https://github.com/simplex-chat/simplexmq/pull/548/files), and if both clients are updated the key exchange will not have this vulnerability. Also, previously created connections should be secure as long as both sides sent the messages, but if you believe that your private key(s) could have been compromised (for example, if you used SimpleX Chat since before we added database encryption), we recommend that you create the new connections with your contacts, at least with the security-critical ones. Simply rotating the connection queue (manual queue rotation is added in version 4.2) will not be sufficient, as this rotation does not re-initialize the ratchets - this is something we will be adding in the future.
+
+#### Keys are stored in unpinned memory and not cleared after their lifetime
+
+The problem here is that the memory with cryptographic keys can be swapped to the storage and potentially accessed by an attacker who has root-level access to the device (or the level of access required to access swap file of the application). So, if you are running SimpleX Chat on desktop you could improve its security by running it in an isolated container.
+
+On mobile operating systems it is less severe as each application already runs in its own container, and applications do not share access to their swap areas (e.g., on Android swap is a [compressed area in RAM](https://developer.android.com/topic/performance/memory-management) not accessible to other applications).
+
+To exploit this issue an attacker needs to have a privileged system access to the device. Also, we believe [Haskell generational garbage collection](https://www.microsoft.com/en-us/research/wp-content/uploads/1993/01/gen-gc-for-haskell.pdf) makes the lifetime of unused memory lower than in other languages.
+
+We will be addressing this issue in the near future, possibly by using library [secure-memory](https://hackage.haskell.org/package/secure-memory-0.0.0.2) created by Kirill Elagin, an engineer at Serokell, or some other similar approach.
+
+### Low severity issues
+
+#### The functions that do string padding and unpadding can throw exceptions
+
+Both these issues are fixed in 4.2 in [this PR](https://github.com/simplex-chat/simplexmq/pull/547/files), with the additional unit tests, and we also validated that even before the fix the strings that would cause such exception were never passed to this function – we could not find the possibility of the attack that would succeed because of this issue.
+
+### What's next
+
+There are areas of SimpleX Chat that were out of scope of this review, specifically:
+
+- the chat protocol implementation and mobile UIs, as they includes no cryptography of networking (with the exception of Android app storing encrypted database passphrase and key exchange/encryption for WebRTC calls).
+- push notifications server that is used by iOS clients.
+
+We will be arranging to review these areas separately.
+
+## The new website
+
+Our [previous website](https://old-website.simplex.chat) was created 2 years ago to present SimpleX idea, there was no SimpleX Chat at the time - we only had a prototype implementation of SimpleX Messaging Protocol server then.
+
+A lot of people told us that our website didn't explain well enough who SimpleX Chat is for, what problems it solves, and how it is different from the alternatives. So, while we love to be focused on the chat application, we decided to make the new one.
+
+We hope that our [new website](https://simplex.chat) better answers these questions. If you think something should be added/removed/changed - please let us know. Thank you!
+
+## SimpleX Chat v4.2 released!
+
+New in this release:
+
+- fixed 3 issues from the security audit!
+- group links - group admins can create the links for new members to join
+- auto-accept contact requests + configure whether to accept incognito and welcome message
+- small things: change group member role, mark chat as unread, send stickers and GIFs from Android keyboards.
+
+Beta features (enable Developer tools to try them):
+
+- manually switch contact or member to another address / server (it has to be supported by both clients to work)
+- receive files faster (enable it in Privacy & Security settings)
+
+### Group links
+
+<img src="./images/20221108-group1.png" width="288"> &nbsp;&nbsp; <img src="./images/20221108-group2.png" width="288">
+
+It's been requested by many users - to be able to join a group via link. Because SimpleX Chat groups are fully decentralised, and there is no server-side state, joining via these links requires the participation of the link creator who has to be online to accept the group joining request.
+
+The way it works under the hood is similar to how contact addresses work:
+
+1. Group admin or owner creates a long term address that is technically the same as a user address, but it is associated with a specific group.
+2. The user that joins the group can identify that this link belongs to some group by an additional piece of data in the link - `{"type": "group", "groupLinkId": "some random string"}`. The ID in this link does not represent a group identity, every time any user creates a new link for the same group, this ID will be different. This ID is used by the joining client to identify the group and automatically accept the invitation when it is received.
+3. When admin receives a connection request, they automatically accept it and send invitation link to join the group.
+4. The joining user compares the ID in the invitation with the ID in the link, and if they match – automatically accepts the invitation.
+
+After that it works as when joining via the manual invitation - the joining user will be establishing the connection with all existing members to be able to send messages to the group.
+
+The link can be created via the group page, as shown on the picture.
+
+We have several groups you can join to ask any questions or just to test the app:
+
+- [#SimpleX-Group](https://simplex.chat/contact#/?v=1-2&smp=smp%3A%2F%2Fu2dS9sG8nMNURyZwqASV4yROM28Er0luVTx5X1CsMrU%3D%40smp4.simplex.im%2FWHV0YU1sYlU7NqiEHkHDB6gxO1ofTync%23%2F%3Fv%3D1-2%26dh%3DMCowBQYDK2VuAyEAWbebOqVYuBXaiqHcXYjEHCpYi6VzDlu6CVaijDTmsQU%253D%26srv%3Do5vmywmrnaxalvz6wi3zicyftgio6psuvyniis6gco6bp6ekl4cqj4id.onion&data=%7B%22type%22%3A%22group%22%2C%22groupLinkId%22%3A%22mL-7Divb94GGmGmRBef5Dg%3D%3D%22%7D): a general group with more than a 100 members where you can ask any questions.

+
+### Auto-accept contact requests
+
+<img src="./images/20221108-address1.png" width="288"> &nbsp;&nbsp; <img src="./images/20221108-address2.png" width="288">
+
+When somebody connects to you via your long-term address you have to manually accept a connection request (it shows in blue color in the list of chats). The feature that we added in this release allows to configure the app to accept contact requests automatically, and also choose whether this contact should receive your main profile or a random incognito profile (independent of the current app setting), and add an optional auto-reply message.
+
+This feature is useful if you publish your address on your webpage or social profile, and do not want to screen people who want to connect to you. You may want to send a standard welcome message, for example, if it is an online store, and you need to share any information with everybody who contacts you.
+
+Our @simplex account that you connect to when you choose "Connect to developers" in the app used this feature for a long time, and now it is available to mobile app users.
+
+### Some small things
+
+1. Changing group member role is a very basic feature, but it was only added in this release.
+
+2. You can now mark a conversation as unread, for example if you accidentally marked all messages as read and you want to review it later.
+
+3. Send stickers and GIFs from Android keyboards, and, finally, the bug with backspace button is resolved as well.
+
+### Change your delivery address (BETA)
+
+<img src="./images/20221108-switch-address.png" width="288">
+
+To manually switch any of your contacts (or a group member to a new server address) enable Developer tools and choose "Change receiving address" on the contact page. As long as they run a new version of the app and online, the switch should only take a few seconds.
+
+That is a major improvement of metadata privacy of SimpleX protocols, because previously, while we didn't have user identifiers, the pairwise identifiers of messaging queues used to deliver messages were used for as long as the contact existed. Now these identifiers are temporary, and in a near future we will be adding automatic rotation of these delivery addresses.
+
+It is also useful when you want to migrate message delivery to another server, for example, if you used SimpleX Chat default servers and now want to self-host your own. Or, maybe, you need to change the address of your server. Previously it would require creating new contacts and losing conversation histories, and now all you have to do is to change server configuration in the app, and when the change of the address is triggered (currently, only manually, and in the near future - automatically), your contacts will be migrated to a new server, without you doing anything - it only requires each party sending 2 messages to negotiate the reconnection, and it would also rotate the encryption keys used for the outer layer of E2E encryption.
+
+### Receive images and small files faster (BETA)
+
+<img src="./images/20221108-faster-images.png" width="288">
+
+From version 4.2 all files smaller than ~92kb (equal to 6 message blocks) will be sent in the same connection where you have the chat, and files smaller than ~231kb (the limit for image size) can also be optionally received via the same connection – the latter requires enabling "Transfer images faster" in Privacy & security settings (it will be available after you enable Developer tools). There are two reasons why it is not on by default yet: 1) we wanted to ensure it is stable; 2) there is a small effect on metadata privacy of having a burst of traffic in the same connection where you are having the main conversation.
+
+This functionality was created for the future voice messages, as they need to be sent without acceptance, so that the recipients can listen to them even when the sender is offline.
