+# 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 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 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 (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.
+
+User Support. If you contact SimpleX Chat any personal data you may share with us is kept only for the purposes of researching the issue and contacting you about your case. We recommend contacting support [via 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), when it is possible.
+
+### Information we may share
+
+We operate our Services using third parties. While we do not share any user data, these third party may access the encrypted user data as it is stored or transmitted via our servers.
+
+We use Third party to provide email services - if you ask for support via email, your and SimpleX Chat email providers may access these emails according their privacy policies and terms of service.
+
+The cases when SimpleX Chat may need to share the data we temporarily store on the servers:
+
+- To meet any applicable law, regulation, legal process or enforceable governmental request.
+- To enforce applicable Terms, including investigation of potential violations.
+- To detect, prevent, or otherwise address fraud, security, or technical issues.
+- To protect against harm to the rights, property, or safety of SimpleX Chat, our users, or the public as required or permitted by law.
+
+At the time of updating this document, we have never provided or have been requested the 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 follow the due legal process.
+
+### Updates
+
+We will update this privacy policy as needed so that it is current, accurate, and as clear as possible. Your continued use of our Services confirms your acceptance of our updated Privacy Policy.
+
+Please also read our Terms of Service.
+
+If you have questions about our Privacy Policy please contact us at chat@simplex.chat.
+
+## Terms of Service
+
+You accept to our Terms of Service ("Terms") by installing or using any of our apps or services ("Services").
+
+**Minimal age**. You must be at least 13 years old to use our Services. The minimum age to use our Services without parental approval may be higher in your country.
+
+**Accessing the servers**. For the efficiency of the network access, the apps access all queues you create on any server via the same network (TCP/IP) connection. Our servers do not collect information about which queues were accessed via the same connection, so we do cannot establish which queues belong to the same users. Whoever might observe your network traffic would know which 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 cyphertext in common. 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.
+
+**Privacy of user data**. We do not retain any data we transmit for any longer than necessary to provide the Services. We only collect aggregate statistics across all users, not per user - we do not have information about how many people use SimpleX Chat (we only know an approximate number of app installations and the aggregate traffic through our servers). In any case, we do not and will not sell or in any way monetize user data.
+
+**Operating our services**. For the purpose of operating our Services, you agree that your end-to-end encrypted messages are transferred via our servers in the United Kingdom, the United States and other countries where we have or use facilities and service providers or partners.
+
+**Software**. You agree to downloading and installing updates to our Services when they are available; they would only be automatic if you configure your devices in this way.
+
+**Traffic and device costs**. You are solely responsible for the traffic and device costs on which you use our Services, and any associated taxes.
+
+**Legal and acceptable usage**. You agree to use our Services only for legal and acceptable purposes. You will not use (or assist others in using) our Services in ways that: 1) violate or infringe the rights of SimpleX Chat, our users, or others, including privacy, publicity, intellectual property, or other proprietary rights; 2) involve sending illegal or impermissible communications, e.g. spam.
+
+**Damage to SimpleX Chat**. You must not (or assist others to) access, use, modify, distribute, transfer, or exploit our Services in unauthorized manners, or in ways that harm SimpleX Chat, our Services, or systems. For example, you must not 1) access our Services or systems without authorization, other than by using the apps; 2) disrupt the integrity or performance of our Services; 3) collect information about our users in any manner; or 4) sell, rent, or charge for our Services.
+
+**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**. Currently the messages are stored in the database on your device without encryption. It means that if you make a backup of the app and store it unecrypted, the backup provider may be able to access the messages.
+
+**No Access to Emergency Services**. Our Services do not provide access to emergency service providers like the police, fire department, hospitals, or other public safety organizations. Make sure you can contact emergency service providers through a mobile, fixed-line telephone, or other service.
+
+**Third-party services**. Our Services may allow you to access, use, or interact with third-party websites, apps, content, and other products and services. When you use third-party services, their terms and privacy policies govern your use of those services.
+
+**Your Rights**. You own the mesasges and information you transmit through our Services. Your recipients are able to retain the messages you receive from you; there is no technical ability to delete data from their devices.
+
+**License**. SimpleX Chat grants you a limited, revocable, non-exclusive, and non-transferable license to use our Services in accordance with these Terms. The source-code of services is available and can be used under [AGPL v3 licence](https://github.com/simplex-chat/simplex-chat/blob/stable/LICENSE)
+
+**SimpleX Chat Rights**. We own all copyrights, trademarks, domains, logos, trade secrets, and other intellectual property rights associated with our Services. You may not use our copyrights, trademarks, domains, logos, and other intellectual property rights unless you have our written permission, and unless under an open-source license distributed together with the source code. To report copyright, trademark, or other intellectual property infringement, please contact chat@simplex.chat.
+
+**Disclaimers**. YOU USE OUR SERVICES AT YOUR OWN RISK AND SUBJECT TO THE FOLLOWING DISCLAIMERS.

+
+**Availability**. Our Services may be interrupted, including for maintenance, upgrades, or network or equipment failures. We may discontinue some or all of our Services, including certain features and the support for certain devices and platforms, at any time.
+

-SimpleX chat prototype is a thin terminal UI on top of [SimpleXMQ](https://github.com/simplex-chat/simplexmq) message broker that uses [SMP protocols](https://github.com/simplex-chat/simplexmq/blob/master/protocol). The motivation for SimpleX chat is [presented here](./simplex.md). See [simplex.chat](https://simplex.chat) website for chat demo and the explanations of the system and how SMP protocol works.

+## Why privacy matters
+
+Everyone should care about privacy and security of their communications - innocuous conversations can put you in danger even if there is nothing to hide.
+
+One of the most shocking stories is the experience of [Mohamedou Ould Salahi](https://en.wikipedia.org/wiki/Mohamedou_Ould_Slahi) that he wrote about in his memoir and that is shown in The Mauritanian movie. He was put into Guantanamo camp, without trial, and was tortured there for 15 years after a phone call to his relative in Afghanistan, under suspicion of being involved in 9/11 attacks, even though he lived in Germany for the 10 years prior to the attacks.
+
+It is not enough to use an end-to-end encrypted messenger, we all should use the messengers that protect the privacy of our personal networks - who we are connected with.
+
+## SimpleX approach to privacy and security
+
+### Complete privacy of your identity, profile, contacts and metadata
+
+**Unlike any other existing messaging platform, SimpleX has no identifiers assigned to the users** - not even random numbers. This protects the privacy of who are you communicating with, hiding it from SimpleX platform servers and from any observers. [Read more](./docs/SIMPLEX.md#full-privacy-of-your-identity-profile-contacts-and-metadata).
+
+### The best protection against spam and abuse
+
+As you have no identifier on SimpleX platform, you cannot be contacted unless you share a one-time invitation link or an optional temporary user address. [Read more](./docs/SIMPLEX.md#the-best-protection-against-spam-and-abuse).
+
+### Complete ownership, control and security of your data
+
+SimpleX stores all user data on client devices, the messages are only held temporarily on SimpleX relay servers until they are received. [Read more](./docs/SIMPLEX.md#complete-ownership-control-and-security-of-your-data).
+
+### Users own SimpleX network
+
+You can use SimpleX with your own servers and still communicate with people using the servers that are pre-configured in the apps or any other SimpleX servers. [Read more](./docs/SIMPLEX.md#users-own-simplex-network).
+
+## 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 Platform design
 
-## Disclaimer
+SimpleX is a client-server network with a unique network topology that uses redundant, disposable message relay nodes to asynchronously pass messages via unidirectional (simplex) message queues, providing recipient and sender anonymity.
 
-This is WIP implementation of SimpleX Chat that implements a new network topology for asynchronous communication combining the advantages and avoiding the disadvantages of federated and P2P networks.
+Unlike P2P networks, all messages are passed through one or several server nodes, that do not even need to have persistence. In fact, the current [SMP server implementation](https://github.com/simplex-chat/simplexmq#smp-server) uses in-memory message storage, persisting only the queue records. SimpleX provides better metadata protection than P2P designs, as no global participant identifiers are used to deliver messages, and avoids [the problems of P2P networks](./docs/SIMPLEX.md#comparison-with-p2p-messaging-protocols).
 
-If you expect software to be reliable most of the time, then this is probably not ready for you yet. We use it ourselves for terminal chat and it seems to work most of the time - we would really appreciate if you try SimpleX Chat and give us your feedback!
+Unlike federated networks, the server nodes **do not have records of the users**, **do not communicate with each other** and **do not store messages** after they are delivered to the recipients. There is no way to discover the full list of servers participating in SimpleX network. This design avoids the problem of metadata visibility that all federated networks have and better protects from the network-wide attacks.
 
-> :warning: **Please note:** The main differentiation of SimpleX network is the approach to internet message routing rather than encryption; for that reason no sufficient attention was paid to either TCP transport level encryption or to E2E encryption protocols - they are implemented in an ad hoc way based on RSA and AES algorithms. See [SMP protocol](https://github.com/simplex-chat/simplexmq/blob/master/protocol/simplex-messaging.md#appendix-a) on TCP transport encryption protocol (AEAD-GCM scheme, with an AES key negotiation based on RSA key hash known to the client in advance) and [this section](https://github.com/simplex-chat/simplexmq/blob/master/rfcs/2021-01-26-crypto.md#e2e-encryption) on E2E encryption protocol (an ad hoc hybrid scheme a la PGP). These protocols will change in a consumer ready version to something more robust.
+Only the client devices have information about users, their contacts and groups.
 
-## Network topology
+See [SimpleX whitepaper](https://github.com/simplex-chat/simplexmq/blob/stable/protocol/overview-tjr.md) for more information on platform objectives and technical design.
 
-SimpleX is a decentralized client-server network that uses redundant, disposable nodes to asynchronously pass messages via message queues, providing receiver and sender anonymity.
+See [SimpleX Chat Protocol](./docs/protocol/simplex-chat.md) for the format of messages sent between chat clients over [SimpleX Messaging Protocol](https://github.com/simplex-chat/simplexmq/blob/stable/protocol/simplex-messaging.md).
 
-Unlike P2P networks, all messages are passed through one or several (for redundancy) servers, that do not even need to have persistence (in fact, the current [SMP server implementation](https://github.com/simplex-chat/simplexmq#smp-server) uses in-memory message storage, persisting only the queue records) - it provides better metadata protection than P2P designs, as no global participant ID is required, and avoids many [problems of P2P networks](https://github.com/simplex-chat/simplex-chat/blob/master/simplex.md#comparison-with-p2p-messaging-protocols).
+## Privacy: technical details and limitations
 
-Unlike federated networks, the participating server nodes **do not have records of the users**, **do not communicate with each other**, **do not store messages** after they are delivered to the recipients, and there is no way to discover the full list of participating servers. SimpleX network avoids the problem of metadata visibility that federated networks suffer from and better protects the network, as servers do not communicate with each other. Each server node provides unidirectional "dumb pipes" to the users, that do authorization without authentication, having no knowledge of the the users or their contacts. Each queue is assigned two RSA keys - one for receiver and one for sender - and each queue access is authorized with a signature created using a respective key's private counterpart.
+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.
 
-The routing of messages relies on the knowledge of client devices how user contacts and groups map at any given moment of time to these disposable queues on server nodes.
+What is already implemented:
 
-## Terminal chat features
+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.
+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.
+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.
 
-- 1-to-1 chat with multiple people in the same terminal window.
-- Group messaging.
-- Sending files to contacts and groups.
-- User contact addresses - establish connections via multiple-use contact links.
-- Auto-populated recipient name - just type your messages to reply to the sender once the connection is established.
-- Demo SMP servers available and pre-configured in the app - or you can [deploy your own server](https://github.com/simplex-chat/simplexmq#using-smp-server-and-smp-agent).
-- No global identity or any names visible to the server(s), ensuring full privacy of your contacts and conversations.
-- E2E encryption, with RSA public key that has to be passed out-of-band (see [How to use SimpleX chat](#how-to-use-simplex-chat)).
-- Message signing and verification with automatically generated RSA keys.
-- Message integrity validation (via including the digests of the previous messages).
-- Authentication of each command/message by SMP servers with automatically generated RSA key pairs.
-- TCP transport encryption using SMP transport protocol.
+We plan to add soon:
 
-RSA keys are not used as identity, they are randomly generated for each contact.
+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 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.

+## For developers
 
-## 🚀 Installation
+You can:
 
-### Download chat client
+- 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 [JavaScipt 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.
 
-#### Linux and MacOS
-
-To **install** or **update** `simplex-chat`, you should run the install script. To do that, use the following cURL or Wget command:
-
-```sh
-curl -o- https://raw.githubusercontent.com/simplex-chat/simplex-chat/master/install.sh | bash
-```
-
-```sh
-wget -qO- https://raw.githubusercontent.com/simplex-chat/simplex-chat/master/install.sh | bash
-```
-
-Once the chat client downloads, you can run it with `simplex-chat` command in your terminal.
-
-Alternatively, you can manually download the chat binary for your system from the [latest stable release](https://github.com/simplex-chat/simplex-chat/releases) and make it executable as shown below.
-
-```sh
-chmod +x <binary>
-mv <binary> ~/.local/bin/simplex-chat
-```
-
-(or any other preferred location on `PATH`).
-
-On MacOS you also need to [allow Gatekeeper to run it](https://support.apple.com/en-us/HT202491).
-
-##### Troubleshooting on Unix
-
-If you get `simplex-chat: command not found` when executing the downloaded binary, you need to add the directory containing it to the [`PATH` variable](https://man7.org/linux/man-pages/man7/environ.7.html) (find "PATH" in page). To modify `PATH` for future sessions, put `PATH="$PATH:/path/to/dir"` in `~/.profile`, or in `~/.bash_profile` if that's what you have. See [this answer](https://unix.stackexchange.com/a/26059) for the detailed explanation on the appropriate place to define environment variables for `bash` and other shells.
-
-For example, if you followed the previous instructions, open `~/.profile` for editing:
-
-```sh
-vi ~/.profile
-```
-
-And add the following line to the end:
-
-```sh
-PATH="$PATH:$HOME/.local/bin"
-```
-
-Note that this will not automatically update your `PATH` for the remainder of the session. To do this, you should run:
-
-```sh
-source ~/.profile
-```
-
-Or restart your terminal to start a new session.
-
-#### Windows
-
-```sh
-move <binary> %APPDATA%/local/bin/simplex-chat.exe
-```
-
-### Build from source
-
-#### Using Docker
-
-On Linux, you can build the chat executable using [docker build with custom output](https://docs.docker.com/engine/reference/commandline/build/#custom-build-outputs):
-
-```shell
-$ git clone git@github.com:simplex-chat/simplex-chat.git
-$ cd simplex-chat
-$ DOCKER_BUILDKIT=1 docker build --output ~/.local/bin .
-```
-
-> **Please note:** If you encounter `` version `GLIBC_2.28' not found `` error, rebuild it with `haskell:8.10.4-stretch` base image (change it in your local [Dockerfile](Dockerfile)).
-
-#### Using Haskell stack
-
-Install [Haskell stack](https://docs.haskellstack.org/en/stable/README/):
-
-```shell
-curl -sSL https://get.haskellstack.org/ | sh
-```
-
-and build the project:
-
-```shell
-$ git clone git@github.com:simplex-chat/simplex-chat.git
-$ cd simplex-chat
-$ stack install
-```
-
-## Usage
-
-### Running the chat client
-
-To start the chat client, run `simplex-chat` from the terminal. If you get `simplex-chat: command not found`, see [Troubleshooting on Unix](#troubleshooting-on-unix).
-
-By default, app data directory is created in the home directory (`~/.simplex`, or `%APPDATA%/simplex` on Windows), and two SQLite database files `simplex.chat.db` and `simplex.agent.db` are initialized in it.
-
-To specify a different file path prefix for the database files use `-d` command line option:
-
-```shell
-$ simplex-chat -d alice
-```
-
-Running above, for example, would create `alice.chat.db` and `alice.agent.db` database files in current directory.
-
-Default SMP servers are hosted on Linode (London, UK and Fremont, CA) - they are [pre-configured in the app](https://github.com/simplex-chat/simplex-chat/blob/master/src/Simplex/Chat/Options.hs#L40). Base-64 encoded string after server host is the transport key digest.
-
-If you deployed your own SMP server(s) you can configure client via `-s` option:
-
-```shell
-$ simplex-chat -s smp.example.com:5223#KXNE1m2E1m0lm92WGKet9CL6+lO742Vy5G6nsrkvgs8=
-```
-
-The base-64 encoded string in server address is the digest of RSA transport handshake key that the server will generate on the first run and output its digest.
-
-You can still talk to people using default or any other server - it only affects the location of the message queue when you initiate the connection (and the reply queue can be on another server, as set by the other party's client).
-
-Run `simplex-chat -h` to see all available options.
-
-### How to use SimpleX chat
-
-Once you have started the chat, you will be prompted to specify your "display name" and an optional "full name" to create a local chat profile. Your display name is an alias for your contacts to refer to you by - it is not unique and does not serve as a global identity. If some of your contacts chose the same display name, the chat client adds a numeric suffix to their local display name.
-
-The diagram below shows how to connect and message a contact:
-
-<div align="center">
-  <img align="center" src="images/how-to-use-simplex.svg">
-</div>
-
-Once you've set up your local profile, enter `/c` (for `/connect`) to create a new connection and generate an invitation. Send this invitation to your contact via any other channel.
-
-You are able to create multiple invitations by entering `/connect` multiple times and sending these invitations to the corresponding contacts you'd like to connect with.
-
-The invitation has the format `smp::<server>::<queue_id>::<rsa_public_key_for_this_queue_only>`. The invitation can only be used once and even if this is intercepted, the attacker would not be able to use it to send you the messages via this queue once your contact confirms that the connection is established.
-
-The contact who received the invitation should enter `/c <invitation>` to accept the connection. This establishes the connection, and both parties are notified.
-
-They would then use `@<name> <message>` commands to send messages. You may also just start typing a message to send it to the contact that was the last.
-
-Use `/help` in chat to see the list of available commands.
-
-### Groups
-
-To create a group use `/g <group>`, then add contacts to it with `/a <group> <name>`. You can then send messages to the group by entering  `#<group> <message>`. Use `/help groups` for other commands.
-
-![simplex-chat](./images/groups.gif)
-
-> **Please note**: the groups are not stored on any server, they are maintained as a list of members in the app database to whom the messages will be sent.
-
-### Sending files
-
-You can send a file to your contact with `/f @<contact> <file_path>` - the recipient will have to accept it before it is sent. Use `/help files` for other commands.
-
-![simplex-chat](./images/files.gif)
-
-You can send files to a group with `/f #<group> <file_path>`.
-
-### User contact addresses (alpha)
-
-As an alternative to one-time invitation links, you can create a long-term address with `/ad` (for `/address`). The created address can then be shared via any channel, and used by other users as a link to make a contact request with `/c <user_contact_address>`.
-
-You can accept or reject incoming requests with `/ac <name>` and `/rc <name>` commands.
-
-User address is "long-term" in a sense that it is a multiple-use connection link - it can be used until it is deleted by the user, in which case all established connections would still remain active (unlike how it works with email, when changing the address results in people not being able to message you).
-
-Use `/help address` for other commands.
-
-> :warning: **Please note:** This is an "alpha" feature - at the moment there is nothing to prevent someone who has obtained this address from spamming you with connection requests; countermeasures will be added soon!  (In the short term, you can simply delete the long-term address you created if it starts getting abused.)
-
-![simplex-chat](./images/user-addresses.gif)
-
-### Access chat history
-
-> 🚧 **Section currently out of date** 🏗
-
-SimpleX chat stores all your contacts and conversations in a local database file, making it private and portable by design, fully owned and controlled by you.
-
-You can search your chat history via SQLite database file:
-
-```
-sqlite3 ~/.simplex/smp-chat.db
-```
-
-Now you can query `messages` table, for example:
-
-```sql
-select * from messages
-where conn_alias = cast('alice' as blob)
-  and body like '%cats%'
-order by internal_id desc;
-```
-
-> **Please note:** SQLite foreign key constraints are disabled by default, and must be **[enabled separately for each database connection](https://sqlite.org/foreignkeys.html#fk_enable)**. The latter can be achieved by running `PRAGMA foreign_keys = ON;` command on an open database connection. By running data altering queries without enabling foreign keys prior to that, you may risk putting your database in an inconsistent state.
+If you are considering developing with SimpleX platform please get in touch for any advice and support.

+## Disclaimers
+
+[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.
+
+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).
+
+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.
+
+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.
+
+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.
+
+Please read more in [Terms & privacy policy](./PRIVACY.md).
+
+## 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.
