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!

WebMoney Keeper
A secret mode in WebMoney wallet chats. The lock in the chat header turns on encryption through the Secret Keeper extension: outgoing messages are sealed right in the browser, incoming ones are opened by the extension. Keys never leave the extension; the server only sees ciphertext.

Works in Chromium browsers (Chrome, Edge, Opera, Yandex Browser); secret mode is text-only.
