Privacy Policy

Last updated: 30 October 2026

In short: we keep only what the server needs to run. Messages in encrypted chats can't be read by us. We don't sell your data, show ads, or track you across the web.

1. Who we are

Signalix Messenger (signalix.chat) is a Matrix-based messaging service operated by the Signalix team. We are the data controller for personal data processed on the Signalix server. Contact: support@signalix.chat.

2. What data we process

Account data: your username, display name, avatar, and a hashed version of your password (we never store your password in plain text). If you add an email address, we store it too.
Messages and files: messages, images and files you send are stored on the server so they can be delivered to you and the people you talk with.
Metadata: which rooms you are in, who you talk with, and when messages are sent. The server needs this to work, even in encrypted chats.
Technical data: IP addresses, device names and access times, kept in logs for security and to prevent abuse.

3. Encryption

Direct chats and private rooms are end-to-end encrypted by default in Element X and the Signalix web app. In encrypted chats, the content of your messages and files is encrypted on your device, and we cannot read it. Public or unencrypted rooms are stored on the server in readable form, so please don't share sensitive information there.

If you lose all your devices and your recovery key, we cannot recover your encrypted messages.

4. Why we process your data

To provide the service you signed up for: creating your account and delivering your messages (performance of a contract, GDPR Art. 6(1)(b)).
To keep the service secure and prevent spam and abuse (legitimate interest, GDPR Art. 6(1)(f)).
To comply with legal obligations where they apply (GDPR Art. 6(1)(c)).

We do not use your data for advertising, profiling or selling to third parties.

5. Federation with other Matrix servers

Matrix is a federated network. If you talk with users on other servers, or join rooms hosted elsewhere, copies of your messages, display name and avatar are sent to those servers. They are run by other people and are covered by their own privacy policies, not ours. Messages already sent to other servers can't be deleted from them by us.

6. Who else handles your data

Hosting: the server runs on infrastructure rented from a third-party hosting provider, which stores the data on our behalf.
Push notifications: mobile apps may use Apple or Google push services to notify you of new messages. For encrypted chats these notifications don't contain message content.
Authorities: we only share data when legally required to do so.

7. How long we keep data

Account data and messages are kept while your account is active.
IP addresses and access logs are kept for a limited time and then deleted automatically.
When you deactivate your account, we remove your profile and stop your access. Messages you already sent may remain visible to the people you sent them to.

8. Your rights

Under the GDPR, you have the right to:

access the personal data we hold about you;
correct inaccurate data;
have your data deleted;
receive your data in a portable format;
object to or restrict certain processing.

To use any of these rights, email support@signalix.chat. You also have the right to lodge a complaint with your local data protection authority.

9. Cookies

This website doesn't use tracking or advertising cookies. The web messenger stores login and encryption data in your browser so you stay signed in.

10. Age

Signalix is not intended for children under 16.

11. Changes

If we change this policy, we will update the date at the top of this page. For significant changes, we will let users know in advance.
