Works with your other apps

Local apps can pair with Secret Keeper over IPC (unix socket / named pipe) and delegate encryption to it - keys never leave the vault. That is how the Tetatet Chat messenger integration works.

How to connect

Our apps

Input Fixer

Typed «Ghbdtn» instead of «Привет»? It notices and retypes it for you. Everything runs locally.

Snip Marker

Snip, mark, send. The easiest way to dress up a screenshot and share it

Tetatet Chat

A messenger that doesn't know you: no phone number, no ads, no tracking.

Installing the extension

The easiest way is to install it from the Chrome Web Store:

Download on Chrome Web Store

Prefer the archive from the site? It installs unpacked:

  1. Download the .zip and unpack it into a folder you keep.
  2. Open chrome://extensions and enable “Developer mode” (top right).
  3. Press “Load unpacked” and choose the unpacked folder.
  4. Pin Secret Keeper to the toolbar - the popup works like the app: create or import a profile with 12 words.
