Step away, and your
screen blurs itself.

microShield watches for your face and covers the screen with frosted glass the moment you leave your desk — so passers-by never see your work. Come back, and it clears instantly. No password needed.

Screen protected while you're away Unblurs automatically when you return
Unlock with your face or Touch ID

Clicks and typing pass straight through the blur — your work never stops.

Features

Everything peeking prevention needs. Nothing else.

Automatic on / off by face

Step away and it blurs after a grace period (10 s by default, adjustable from 5 s to 1 min). Come back and it clears instantly.

A blur, not a lock

No password to get back in. Clicks and keystrokes pass through the blur to your apps, so nothing interrupts your work.

Privacy first

Video is processed only on this Mac — never stored, never sent. Only an irreversible feature vector is saved; no photos of your face.

Light on power

5 fps capture with adaptive sampling: about 5% of one efficiency core. Pauses automatically during display sleep and clamshell mode.

Enroll in ~2 seconds

One click while watching the camera preview. Manual unlock with Touch ID or your password is always available.

No false blurs in a crowd

Up to three faces are matched at once — if you're there, the screen stays clear even when someone stands in front of you.

FAQ

Frequently asked questions

Is the video sent anywhere?

No. Camera frames are processed entirely on this Mac and are never stored or transmitted. Nothing goes over the network.

Are photos of my face saved?

No. Only an irreversible feature vector is stored — the original face can't be reconstructed from it, and no images are kept.

Will it drain my battery?

Barely. 5 fps capture plus adaptive sampling measures around 5% of one efficiency core, and monitoring pauses automatically during display sleep and clamshell mode.

Is it safe without a password?

The blur is a shoulder-surfing shield, not a lock — its job is hiding your screen the moment you step away. For strong protection, combine it with the macOS lock screen.
