It stays on your Mac.

Deft collects nothing, has no accounts, no ads, and no tracking. It asks only for the macOS permissions it needs — and the code is open, so you can verify exactly what it does.

  • Accessibility — move and resize windows, translate shortcuts.
  • Screen Recording — draw live previews. Nothing is ever recorded or sent.
  • Input Monitoring — tell a Windows keyboard from a Mac one.
  • The only network use is checking for updates on GitHub.
