Umbra is a free, open-source privacy screen for Windows. It uses your webcam to notice when you look away and instantly covers your screen; look back and it's gone in 0.15 s. On-device face tracking (MediaPipe) reads head direction and eye gaze, and a one-minute calibration fits it to your desk. Cover with a blur, your own image, a GIF/video or a solid colour. Press F8 to toggle, or pause from the tray. Nothing is recorded or uploaded.
