IntruderCheck

IntruderCheck is a free and ad-free Chrome extension designed to protect your device by capturing photos of anyone who unlocks your phone without permission. Utilizing your front camera, IntruderCheck snaps a picture each time your device is unlocked, ensuring you can verify any intruders. The captured images are discreetly hidden from your regular photo gallery and can only be accessed with a secured passcode, providing an extra layer of security.

This extension maintains a history of the most recent 10 unlock events—expandable when you upgrade to PRO mode. It supports monitoring failed password attempts and runs in the background while displaying a subtle notification bar icon that you can hide. IntruderCheck requires necessary permissions to function effectively, including camera access and device administrator privileges for comprehensive monitoring.

Easily view captured intruder images with timestamps through the extension interface. IntruderCheck is perfect for users looking to enhance their phone's security by being alerted to unauthorized access attempts. The developer welcomes help for localization to make the tool accessible globally.
