Privacy Policy for Voice Screen Lock
Effective Date: January 1, 2026

1. Introduction
Voice Screen Lock ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how your personal information is collected, used, and disclosed by Voice Screen Lock.

2. Information We Collect
We prioritize data minimization. The Application collects the following types of information:

Audio Data: Your voice input is processed in real-time to authenticate your identity. This processing occurs locally on your device. We do not upload, store, or transmit your voice recordings to any server.
Usage Data: For the App Lock feature, we access information about which applications are being opened on your device. This data is used solely to determine whether an app should be locked and is never uploaded or stored outside your device.
Biometric Data: If enabled, the app uses your device's built-in biometric sensors (e.g., fingerprint). We do not have access to your actual biometric data; we only receive a confirmation of successful authentication from the system.
Device Data: We may collect non-identifiable information about your device, such as model, operating system version, and screen size, to ensure app compatibility and stability.
3. How We Use Your Information
Authentication: To operate the core functionality of unlocking your device or specific apps using your voice or biometrics.
App Protection: To provide secure locking mechanisms for your installed applications via the App Lock feature.
App Improvement: To analyze app performance and improve user experience based on aggregated, anonymous data.
4. Permissions
To function correctly, the Application requires the following permissions:

Record Audio: Essential for capturing voice commands for unlocking.
System Alert Window (Overlay): Required to display the lock screen over other apps.
Usage Stats: Required for the App Lock feature to detect when a locked app is being launched.
Biometric/Fingerprint: To allow optional biometric unlocking.
Post Notifications: To show the status of the lock service in your notification tray.
Read Phone State: Necessary to detect incoming calls and pause the lock screen, ensuring you can answer calls without obstruction.
5. Advertising and Third-Party Services
We use Google AdMob to display advertisements in the Application. These third-party services may collect non-personal device identifiers and usage data for the purpose of serving relevant ads. You can review Google's Privacy Policy here.

6. Data Storage and Security
All sensitive data, including voice models, backup PINs/Patterns, and local app lock settings, is stored locally on your device using industry-standard encryption standards. We do not have access to this data, and it is never shared with third parties.

7. Service Providers
We do not share your personal data with third-party service providers for marketing or tracking purposes. Any third-party SDKs used (e.g., for ads or crash reporting) operate under strict data privacy agreements and collect only anonymous data.

8. Children's Privacy
Our Service does not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13. If we discover that a child under 13 has provided us with personal information, we immediately delete this from our records.

9. Changes to This Privacy Policy
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Effective Date" at the top.
