Quiet, intelligent protection

Step away. WatchCat steps in.

A Mac automatically enters protection after its owner leaves the desk 01

Protection starts automatically

WatchCat briefly activates the camera only after your chosen keyboard and mouse idle time. The camera turns off as soon as the check is complete.

WatchCat recognizes the owner returning to the Mac on-device 02

Recognizes its owner

A dedicated face identity model creates a feature vector on your Mac. WatchCat recognizes you and starts the screen saver when the person is not you.

WatchCat's simple first-run onboarding 03

Friendly first-run guidance

A clear welcome flow helps you finish setup the first time you open WatchCat, so protection can begin quietly in the background.

Pause protection with one click when lending the Mac to a colleague 04

Pause with one click

Turn off protection to pause all checks. Your face data and settings remain on the Mac, ready when you turn protection back on.

Modes switch automatically

Basic or intelligent—WatchCat knows.

Before face enrollment

Basic protection

No camera is used. After the idle time is reached, WatchCat starts the lock-screen countdown directly and reminds you about owner recognition next time.

After face enrollment

Owner recognition

After your Mac becomes idle, WatchCat checks the primary face. If it is you, the screen stays available; otherwise, the Mac locks as usual.

While on battery

Automatic power saving

Image processing runs less often and each check lasts about three seconds at most. After recognizing you, WatchCat waits at least 30 minutes before checking again.

Owner recognition turns on automatically after enrollment. Delete your face data and WatchCat returns to basic protection—no manual mode switching required.

Local privacy, built into the product

Every recognition check stays on this Mac.

Camera frames are used only for immediate face detection and identity-vector generation. WatchCat saves no original photos or videos, includes no advertising or tracking services, and never sends face features to a server.
