Privacy Policy

Effective Date: May 15, 2026

Digital Insider ("we", "us", or "our") operates the Number Ninja mobile application. This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our app.

1. Information Collection and Use

Number Ninja is a privacy-focused educational game. We do not collect, store, or transmit any personal information to external servers. Everything happens locally on your device.

• User Profiles: Your chosen Ninja name and icon are stored only on your device to personalize the game interface.

• Game Progress: Levels unlocked and high scores are saved locally so you can resume your progress.

• Performance Stats: Your solve times and badges are calculated and stored on your device to help you track your improvement.

2. Local Data Storage

The app uses SharedPreferences to save your data locally. This information never leaves your phone. If you clear the app data or uninstall the app, this progress will be permanently deleted.

3. Device Permissions

To provide a full gaming experience, the app may use:

• Vibration: For haptic feedback during gameplay (e.g., when you get an answer wrong).

• Audio: To play sound effects for correct answers.

4. Third-Party Services

Number Ninja does not use any third-party analytics, advertising IDs, or cloud sync services. We do not share any data with third parties because we don't collect any in the first place.

5. Children’s Privacy

Our app is designed for students and math lovers of all ages. We do not collect any personal data, making it a safe environment for children.

6. Security

Since all data is stored locally on your device, its security depends on your device's security settings. We do not have access to your device or the data stored by the app.

7. Changes to This Policy

If we change our privacy practices in the future, we will update this page. Since we do not collect your email or contact info, please check this page periodically for any updates.
