Security & Privacy

Delta Chat provides end-to-end encryption for encrypted chats. Verify encryption in your client; this relay does not enforce encrypted content on every delivery path.

Policy

No tracking

No analytics, ads, counters, or third-party scripts are loaded by the public pages.

Dear users, please note that DeltaChat can be used for both secure, encrypted and insecure (traditional email) communication.

To maintain full security, make sure to follow these guidelines:

Stop using classic email: In DeltaChat settings, under Advanced, set "Classic email" to "No".
Identifying unsafe messages: Messages that appear with an envelope icon or grey icon are insecure.
Start chats only via link: Never send messages directly to an ID (email address).
Server policy limits: Configured SMTP PGP checks and IMAP APPEND validation allow specific exceptions. Inbound /mxdeliv delivers directly to storage without SMTP PGP/DKIM checks, and local admin notices are intentionally unencrypted. HTTPS protects transport, not message content from the receiving server.

Note for administrators: If you are using older versions of micromad, make sure to update your server to protect user security.

End-to-end encryption

For end-to-end encrypted chats, content is readable by recipients, not the relay. Account and routing metadata remain visible to the server.

Check encryption

Do not assume every received message is encrypted. Server-side SMTP checks do not cover inbound HTTP federation; verify encryption and contacts in Delta Chat.
