Privacy Policy

Effective Date: February 22, 2026

This Privacy Policy describes how App Lock ("we", "us", or "our") collects, uses, and protects your information when you use our mobile application. We are committed to safeguarding your privacy and ensuring the security of your personal data.

1. Information We Collect

1.1 Information You Provide

• Lock Credentials: PIN codes, pattern lock data, and fingerprint authentication preferences you set up within the app. These are stored locally on your device and are never transmitted to our servers.
• App Lock Preferences: Your selection of which applications to lock and your configuration settings.

1.2 Information Collected Automatically

• Usage Statistics Access: The app requires access to Usage Statistics (PACKAGE_USAGE_STATS) to detect which application is currently in the foreground. This data is processed locally on your device and is not collected or stored by us.
• Installed Applications: The app reads your list of installed applications to display them for locking. This information remains on your device.
• Camera Access: If enabled, the app may capture a photo when an incorrect unlock attempt is made (intruder selfie feature). These photos are stored locally on your device only.
• Device Information: Basic device information may be collected for analytics and crash reporting purposes, including device model, operating system version, and app version.
• Location Data: The app may request access to location data for Bluetooth connectivity features. Location data is not stored or transmitted to external servers.

2. How We Use Your Information

We use the information described above solely for the following purposes:

• To provide the core app-locking functionality and protect your selected applications.
• To detect the foreground application and display the lock screen when necessary.
• To authenticate you via PIN, pattern, or fingerprint.
• To display advertisements in the free version of the app.
• To improve app performance, stability, and user experience.
• To send push notifications related to app functionality.

3. Third-Party Services

The free version of App Lock uses the following third-party services that may collect information:

• Google AdMob: Used to serve advertisements. AdMob may collect device identifiers, IP address, and usage data. Please refer to Google's Privacy Policy for more details.
• Google Firebase: Used for analytics, crash reporting, and push notifications (Firebase Cloud Messaging). Please refer to Firebase Privacy Policy for more details.
• Google Play Billing: Used for in-app purchases in the pro version. Governed by Google's Privacy Policy.

4. Permissions

App Lock requests the following permissions to provide its core functionality:

• Usage Access (PACKAGE_USAGE_STATS): To detect the currently active app and trigger the lock screen.
• Display Over Other Apps (SYSTEM_ALERT_WINDOW): To show the lock screen overlay on top of protected apps.
• Biometric/Fingerprint: To enable fingerprint-based unlocking.
• Camera: For the intruder selfie feature when wrong credentials are entered.
• Internet & Network State: For serving ads (free version), analytics, and push notifications.
• Boot Completed: To restart the lock service after device reboot.
• Foreground Service: To keep the lock service running reliably.
• Notifications: To display the persistent service notification and alerts.
• Location & Bluetooth: For Bluetooth-related features (e.g., auto-unlock when connected to trusted devices).
• Vibrate: For haptic feedback during lock screen interactions.
• Wake Lock: To ensure the lock service operates correctly during screen events.
• Alarms: To schedule service restart tasks for reliability.

5. Data Storage and Security

All sensitive data, including your lock credentials, locked app selections, and intruder photos, is stored locally on your device. We do not operate external servers that store your personal data. We implement reasonable security measures to protect data stored on your device through the app, including encrypted storage for lock credentials.

6. Data Sharing

We do not sell, trade, or otherwise transfer your personal information to third parties. Information may be shared only in the following circumstances:

• With third-party service providers (Google AdMob, Firebase) as described in Section 3, solely for the purposes of ad serving, analytics, and crash reporting.
• If required by law, regulation, or legal process.

7. Children's Privacy

App Lock is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such information, please contact us so we can promptly delete it.

8. Data Retention

Your data is retained locally on your device for as long as the app is installed. Uninstalling the app will remove all locally stored data, including your lock settings, preferences, and any intruder photos. Third-party services may retain data according to their own privacy policies.

9. Your Rights

You have the right to:

• Uninstall the app at any time, which removes all locally stored data.
• Revoke any permissions granted to the app through your device settings.
• Opt out of personalized advertising through your device's ad settings.
• Request information about data collected by third-party services.

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be reflected by updating the "Effective Date" at the top of this page. We encourage you to review this Privacy Policy periodically for any changes. Continued use of the app after changes constitutes acceptance of the updated policy.
