Integrations

Apps on the same device can hand encryption over to Secret Keeper: they talk to it through a local channel, and the keys never leave the vault.

You approve every connection personally and can revoke it at any moment in Settings, under "Connected apps".

Tetatet Chat

This is a messenger by the same team. With Secret Keeper connected it encrypts your conversations end-to-end: messages are sealed and opened by your vault; the app sees them decrypted, the server never does!
