QuietGlass is a free, open-source Mac app for screen privacy. Look away with compatible AirPods and your screen blurs. Your camera can spot another face in view and warn you or blur the screen, even while you're still looking. Protect a window or selected area, blur sensitive text, or keep your active window clear with Focus mode. Optional owner recognition checks it's you before clearing camera protection. Native Swift, notch controls, and processing on your Mac. macOS 14+.
