AppLocker – Privacy Policy

Last updated: March 2026

Overview

AppLocker ("the App") is developed by DevCodeApps. This Privacy Policy explains how we collect, use, and protect your information when you use AppLocker.

Data We Collect

• Installed app list: We query the list of installed applications on your device solely to display them in the app list so you can choose which apps to lock. This data never leaves your device.
• Camera (Intruder Selfie): If you enable the Intruder Selfie feature (Premium), the front camera captures a photo when someone enters the wrong PIN. Photos are stored locally on your device only and are never uploaded.
• Usage Stats: We use Android's UsageStatsManager to detect when a locked app is launched. This data is processed locally in real time and is never stored or transmitted.
• Biometric data: Fingerprint/biometric authentication is handled entirely by the Android OS (BiometricPrompt). We do not access or store any biometric data.
• Notifications: We send local notifications for break-in alerts. No notification data is sent to external servers.

Data We Do NOT Collect

• We do not collect personal information (name, email, phone number).
• We do not track your location.
• We do not transmit app usage data, intruder photos, or any on-device data to our servers.
• We do not sell or share your data with third parties.

Third-Party Services

• Google AdMob: The free version displays ads served by Google AdMob. AdMob may collect an advertising ID (GAID) for ad personalization. See Google's Privacy Policy.
• Google Play Billing: In-app purchases are processed by Google Play. We do not handle or store payment information directly.

Permissions Explained

• QUERY_ALL_PACKAGES: Required to list all installed apps for the app-locking interface.
• FOREGROUND_SERVICE / FOREGROUND_SERVICE_SPECIAL_USE: Keeps the app monitor running to intercept locked app launches.
• SYSTEM_ALERT_WINDOW: Required to display the lock screen over other apps.
• PACKAGE_USAGE_STATS: Detects which app is currently in the foreground.
• CAMERA: Used only for the Intruder Selfie premium feature.
• USE_BIOMETRIC: Allows fingerprint unlock (Premium feature).
• RECEIVE_BOOT_COMPLETED: Restarts the lock service automatically on device reboot.

Data Security

Your PIN is stored locally on your device in a hashed format (SHA-256). All sensitive data remains on your device. We do not operate servers that receive personal data from this app.

Children's Privacy

AppLocker is not directed at children under 13. We do not knowingly collect data from children.

Changes to This Policy

We may update this Privacy Policy. Updates will be reflected with a new "Last updated" date. Continued use of the App after changes constitutes acceptance of the revised policy.
