How it works
Detects. Decides. Shields.
Three steps, entirely on your device — nothing ever leaves your machine.
Watches for a second face
Your webcam continuously checks for another face entering the frame — nothing is recorded or sent anywhere.
Decides instantly, on-device
An on-device machine learning model makes the call in real time, right on your machine. No cloud round-trip, ever.
Shields your screen
The moment a second face is detected, PrivacyGuard automatically shields your screen — near-instant, no action needed.
The core difference
Nothing ever leaves your device
Everything PrivacyGuard does runs locally. No uploads, no remote storage, no account required — the opposite of typical cloud-based monitoring tools.
