LOCK-IN is an AI calorie tracker, food tracker and intermittent fasting tracker built for sustainable weight loss.

ACCESSIBILITY SERVICE DISCLOSURE
LOCK-IN uses Android's AccessibilityService API solely to power the optional Focus Gate app blocker. If you choose to enable Focus Gate and grant the accessibility permission, the service is notified when an app is opened so LOCK-IN can redirect you away from apps you personally chose to block during a focus session. The service only checks the name of the app being opened — it does not read your screen content, keystrokes or passwords, and it never collects, stores or shares personal or sensitive data. You can disable it at any time in your device's Settings > Accessibility.
