Private beta · macOS · Apple Silicon
Encrypted vaults without the terminal
Create, unlock, and lock encrypted folders on your Mac. Personal is free for one password vault; Pro adds Nostr, Amber, the menu bar, open at login, and more.
Beta builds are Apple Silicon only and not notarized yet — macFUSE required. Pro licenses are available for purchase on request; free beta keys go to testers. Linux builds for Pro license holders are provided on request. Intel Macs and Windows are planned for launch.
What it does
-
Vaults in Finder
Create a new encrypted folder or add an existing one. Unlocked vaults mount like any drive — drag files in and out as usual.
-
Unlock your way
Personal unlocks with a password. Pro adds a Nostr key or Amber as a remote signer — your private key never leaves your phone.
-
Lock in one click
Unmount cleanly when you're done. Pro can optionally snapshot a backup copy each time a vault locks.
-
Always within reach
Pro adds a menu bar tray and open-at-login — open a vault in Finder, unlock, or lock all without hunting for the window.
-
Proven encryption
Built on gocryptfs: AES-256-GCM with encrypted filenames. No new crypto to trust, and no terminal to wrangle.
-
Yours, offline
Files stay on your Mac and your license is verified locally. No account, no cloud, nothing phoning home.
How it works
-
Download the app
Install CryptKeeper on your Mac (see unsigned-build steps below). Install macFUSE separately — the app shows a banner with the link if it's missing.
-
Request a Pro beta key
Pro licenses are available for purchase on request, and free beta keys go to Apple Silicon Mac testers who share feedback — reply on Stacker News or Nostr, or email support with your use case. Linux builds for Pro license holders are provided on request. Intel Macs and Windows are planned for launch.
-
Activate & use
Paste your Pro license key in Settings → License. Create vaults, mount them in Finder, lock when you're done — and send feedback.

Requirements
CryptKeeper runs locally on your Mac. Beta builds need two things:
macOS 11+ · Apple Silicon
Private beta builds run on M-series Macs (M1, M2, M3, M4, and later).
macFUSE
Free, one-time install from macfuse.github.io — not bundled with CryptKeeper. If it's missing, the app shows an in-app banner and blocks vault mount until you install it.
Intel Macs and Windows
Planned for launch — beta builds today are Apple Silicon only, so neither has a download yet. Linux builds for Pro license holders are provided on request.
