The Matrix protocol is designed with your privacy and data sovereignty in mind.
Because it is a decentralised, federated service with cryptographically-validated message integrity, there are a few important things to know before you use the Service.
- When you send messages or files in a room, a copy of the data is sent to all participants in the room.
If these participants are registered on remote homeservers, your username, display name, messages and files may be replicated across each participating homeserver.
- The developer of this app collects no personal (or other) information by means of this app.
- Please refer to the privacy policy of your homeserver operator for details if you wish to request a removal of your data.
- The app allows users to select the matrix.org homeserver, or register/log-in to any other available homeserver.
Before choosing the matrix.org homeserver, please review their [privacy policy](https://matrix.org/legal/privacy-notice) and [code of condcuct](https://matrix.org/legal/code-of-conduct).
If you choose a different homeserver, please review their respective privacy policy and applicable terms before use.
The homeserver the user is using may provide a range of integrations in the form of Widgets (web applications accessed as part of the Matrix Client webapp) and Bots (automated participants in rooms).
Bots and Widgets have access to the messages and files in rooms inwhich they participate.
The app contains [Firebase Cloud Messaging](https://firebase.google.com/support/privacy/) services that comunicate with the server maintained by [The Matrix.org Foundation](https://matrix.org/legal/privacy-notice) and [Element](https://element.io/privacy) in order to provide efficient push notifications.
The app developer has no control over the data stored on your homeserver.
You may wish to request your homeserver operator to forget your data if you deactivate your account.
Each user in a Matrix conversation receives their own copy of all messages and files in that conversation (similar to email), so the homeserver operator might ensure data is forgotten by ensuring that your datais not shared further and is not visible to future users – please refer to the privacy policy of your homeserver for details.
In case you use the matrix.org homeserver, you can find their privacy policy [here](https://matrix.org/legal/privacy-notice).
Redactions only remove message content, your display name and avatar – your username will still be visible. Federated homeservers and some matrix clients may not honour the redaction request.
We never knowingly collect or maintain information in the app, through any of the Services provided, from those we know are under 16, and no part of the app is structured to attract anyone under 16.
If you are under 16, please do not use the Service.
