+# 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.
+
+### 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.
+
+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.
+
+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, 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.
+
+### 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 users - 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.

+
+**Limitation of liability**. THE SIMPLEX PARTIES WILL NOT BE LIABLE TO YOU FOR ANY LOST PROFITS OR CONSEQUENTIAL, SPECIAL, PUNITIVE, INDIRECT, OR INCIDENTAL DAMAGES RELATING TO, ARISING OUT OF, OR IN ANY WAY IN CONNECTION WITH OUR TERMS, US, OR OUR SERVICES, EVEN IF THE SIMPLEX PARTIES HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR AGGREGATE LIABILITY RELATING TO, ARISING OUT OF, OR IN ANY WAY IN CONNECTION WITH OUR TERMS, US, OR OUR SERVICES WILL NOT EXCEED ONE DOLLAR ($1). THE FOREGOING DISCLAIMER OF CERTAIN DAMAGES AND LIMITATION OF LIABILITY WILL APPLY TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW. THE LAWS OF SOME JURISDICTIONS MAY NOT ALLOW THE EXCLUSION OR LIMITATION OF CERTAIN DAMAGES, SO SOME OR ALL OF THE EXCLUSIONS AND LIMITATIONS SET FORTH ABOVE MAY NOT APPLY TO YOU.
