1. Information Collection and Use

The Application collects information when you download and use it. This information may include usage data, device information, and interactions with the Application.

2. App Permissions and Functionality

To provide its core functionality, ZenBlack requires specific permissions. By using the app, you grant permission for:

• Overlay Permission (SYSTEM_ALERT_WINDOW): This is required to draw the black screen overlay on top of other apps (such as video players) to simulate a "screen off" mode while allowing audio to continue.
• Foreground Service (FOREGROUND_SERVICE_SPECIAL_USE): The app runs a foreground service to ensure the black screen overlay remains active and accessible via the floating button while you interact with other content. This service is essential for the app's battery-saving utility.

3. Data Safety and Security

The Service Provider values your trust in providing us your Personal Information, thus we are striving to use commercially acceptable means of protecting it. But remember that no method of transmission over the internet, or method of electronic storage is 100% secure and reliable, and we cannot guarantee its absolute security.

4. Children’s Privacy

These Services do not address anyone under the age of 13. The Service Provider does not knowingly collect personally identifiable information from children under 13. If it is discovered that a child under 13 has provided personal information, the Service Provider will immediately delete this from their servers. If you are a parent or guardian and you are aware that your child has provided us with personal information, please contact the Service Provider so that they will be able to take necessary actions.

5. Changes to This Privacy Policy

The Service Provider may update our Privacy Policy from time to time. Thus, you are advised to review this page periodically for any changes.
