# Get started with Locke

Locke is a desktop app that masks sensitive data on your device before it reaches the AI. The Locke Extension covers AI websites. A proxy on your own machine covers what your terminal, scripts and SDKs send to AI APIs. Early Access builds target x64 Windows and Linux, and macOS is coming soon.
