 # SimpleX Chat Terms & Privacy Policy
 
-SimpleX Chat is the first communication platform that has no user profile IDs of any kind, not even random numbers. 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 cannot observe your connections graph.
-
-If you believe that some of the clauses in this document are not aligned with our mission or principles, please raise it with us via [email](chat@simplex.chat) or [chat](https://simplex.chat/contact#/?v=1&smp=smp%3A%2F%2FPQUV2eL0t7OStZOoAsPEV2QYWt4-xilbakvGUGOItUo%3D%40smp6.simplex.im%2FK1rslx-m5bpXVIdMZg9NLUZ_8JBm8xTt%23%2F%3Fv%3D1%26dh%3DMCowBQYDK2VuAyEALDeVe-sG8mRY22LsXlPgiwTNs9dbiLrNuA7f3ZMAJ2w%253D%26srv%3Dbylepyau3ty4czmn77q4fglvperknl4bi2eb2fdy2bh4jxtf32kf73yd.onion).

 ## Privacy Policy
 
-SimpleX Chat Ltd. ("SimpleX Chat") uses the best industry practices for security and encryption to provide secure [end-to-end encrypted](./docs/GLOSSARY.md#end-to-end-encryption) messaging via private connections. This encryption cannot be compromised by the servers via [man-in-the-middle attack](./docs/GLOSSARY.md#man-in-the-middle-attack).
-
-SimpleX Chat is built on top of SimpleX messaging and application platform that uses a new message routing protocol allowing to establish private connections 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 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
 
-#### User profiles
+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.
 
-We do not store user profiles. The profile you create in the app is local to your device.
+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.
 
-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.
-
-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 two anonymous unique cryptographic keys, different for each queue, and separate for sender and recipient of the messages.
-
-#### 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
+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.
 
 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.
 
-#### SimpleX Directory Service
-
-[SimpleX directory service](./docs/DIRECTORY.md) stores: your search requests, the messages and the members profiles in the group. You can connect to SimpleX Directory Service via [this address](https://simplex.chat/contact#/?v=1-4&smp=smp%3A%2F%2Fu2dS9sG8nMNURyZwqASV4yROM28Er0luVTx5X1CsMrU%3D%40smp4.simplex.im%2FeXSPwqTkKyDO3px4fLf1wx3MvPdjdLW3%23%2F%3Fv%3D1-2%26dh%3DMCowBQYDK2VuAyEAaiv6MkMH44L2TcYrt_CsX3ZvM11WgbMEUn0hkIKTOho%253D%26srv%3Do5vmywmrnaxalvz6wi3zicyftgio6psuvyniis6gco6bp6ekl4cqj4id.onion).

 **Keeping your data secure**. SimpleX Chat is the first messaging platform that is 100% private by design - we neither have ability to access your messages, nor we have information about who you communicate with. That means that you are solely responsible for keeping your device and your user profile safe and secure. If you lose your phone or remove the app, you will not be able to recover the lost data, unless you made a back up.
 
-**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 application you use. Legacy databases created prior to 2023 or in CLI (terminal) app may remain unencrypted, and it will be indicated in the app. In this case, if you make a backup of the app data and store it unencrypted, the backup provider may be able to access the messages. Please note, that the beta version of desktop app currently stores the database passphrase in the configuration file in plaintext, so you may need to remove passphrase from the device via the app configuration.

-## Connect to the team
-
-You can connect to the team via the app using "chat with the developers button" available when you have no conversations in the profile, "Send questions and ideas" in the app settings or via our [SimpleX address](https://simplex.chat/contact#/?v=1&smp=smp%3A%2F%2FPQUV2eL0t7OStZOoAsPEV2QYWt4-xilbakvGUGOItUo%3D%40smp6.simplex.im%2FK1rslx-m5bpXVIdMZg9NLUZ_8JBm8xTt%23%2F%3Fv%3D1%26dh%3DMCowBQYDK2VuAyEALDeVe-sG8mRY22LsXlPgiwTNs9dbiLrNuA7f3ZMAJ2w%253D%26srv%3Dbylepyau3ty4czmn77q4fglvperknl4bi2eb2fdy2bh4jxtf32kf73yd.onion). Please connect to:
-
-- to ask any questions
-- to suggest any improvements
-- to share anything relevant
-
-We are replying the questions manually, so it is not instant – it can take up to 24 hours.
-
-If you are interested in helping us to integrate open-source language models, and in [joining our team](./docs/JOIN_TEAM.md), please get in touch.
-
-## Join user groups
-
-You can join the groups created by other users via the new [directory service](https://simplex.chat/contact#/?v=1-4&smp=smp%3A%2F%2Fu2dS9sG8nMNURyZwqASV4yROM28Er0luVTx5X1CsMrU%3D%40smp4.simplex.im%2FeXSPwqTkKyDO3px4fLf1wx3MvPdjdLW3%23%2F%3Fv%3D1-2%26dh%3DMCowBQYDK2VuAyEAaiv6MkMH44L2TcYrt_CsX3ZvM11WgbMEUn0hkIKTOho%253D%26srv%3Do5vmywmrnaxalvz6wi3zicyftgio6psuvyniis6gco6bp6ekl4cqj4id.onion). We are not responsible for the content shared in these 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, but only once. Once the group has more than 10 members it can be submitted to [SimpleX Directory Service](./docs/DIRECTORY.md) where the new users will be able to discover it.
-
-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 users group](https://simplex.chat/contact#/?v=1-4&smp=smp%3A%2F%2FPQUV2eL0t7OStZOoAsPEV2QYWt4-xilbakvGUGOItUo%3D%40smp6.simplex.im%2Fos8FftfoV8zjb2T89fUEjJtF7y64p5av%23%2F%3Fv%3D1-2%26dh%3DMCowBQYDK2VuAyEAQqMgh0fw2lPhjn3PDIEfAKA_E0-gf8Hr8zzhYnDivRs%253D%26srv%3Dbylepyau3ty4czmn77q4fglvperknl4bi2eb2fdy2bh4jxtf32kf73yd.onion&data=%7B%22type%22%3A%22group%22%2C%22groupLinkId%22%3A%22lBPiveK2mjfUH43SN77R0w%3D%3D%22%7D)

-## 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.

-2. _Why should I not just use Signal?_ Signal is a centralized 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.
+2. _Why should I not just use Signal?_ This [post](https://github.com/dessalines/essays/blob/master/why_not_signal.md) shows why Signal cannot be considered a private messenger. Signal is a centralised platform that uses phone numbers to identify its users and their contacts.
 
-3. _How is it different from Matrix, Session, Ricochet, Cwtch, etc., that also don't require user identities?_ 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.

-## Privacy and security: technical details and limitations
-
-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](./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.
-
-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.
+See [SimpleX whitepaper](https://github.com/simplex-chat/simplexmq/blob/master/protocol/overview-tjr.md) for more information on platform objectives and technical design.
 
 ## For developers
 
-You can:
+We plan that the SimpleX platform will grow into the platform supporting any distributed Internet application. This will allow you to build any service that people can access via chat, with custom web-based UI widgets that anybody with basic HTML/CSS/JavaScript knowledge can create in a few hours.
 
-- use SimpleX Chat library to integrate chat functionality into your mobile apps.
-- create chat bots and services in Haskell - see [simple](./apps/simplex-bot/) and more [advanced chat bot example](./apps/simplex-bot-advanced/).
-- create chat bots and services in any language running SimpleX Chat terminal CLI as a local WebSocket server. See [TypeScript SimpleX Chat client](./packages/simplex-chat-client/) and [JavaScript chat bot example](./packages/simplex-chat-client/typescript/examples/squaring-bot.js).
-- run [simplex-chat terminal CLI](./docs/CLI.md) to execute individual chat commands, e.g. to send messages as part of shell script execution.
+You already can:
+
+- use SimpleX Chat library to integrate chat functionality into your apps.
+- use SimpleX Chat bot templates in Haskell to build your own chat bot services (TypeScript SDK is coming soon).
