Privacy Policy

Mathematical Formulas provides mathematical reference content stored on your device. The main screen also displays advertising provided by Google AdMob, which may process information as described below.

1. Information We Collect

We do not ask you to create an account or provide your name, contact details, or precise location. The Google Mobile Ads SDK may automatically collect and share your IP address, interactions with the app and ads, diagnostic information, and device identifiers such as the Android advertising ID or app set ID. Google uses this information for advertising, measurement, and fraud prevention. Data processed can depend on your device settings and privacy choices.

2. How the App Works

The app provides mathematical reference content stored locally on your device. Its core features do not require an account or an internet connection. Loading ads and privacy messages requires a network connection and may transmit information to Google.

3. Device Permissions

The app does not request sensitive device permissions such as precise location, camera, microphone, contacts, phone, or storage access. The advertising SDK uses network access and may access the Android advertising ID when available.

4. Advertising and Analytics

The main screen uses Google AdMob to display a banner ad. We do not include a separate analytics SDK. Google may process information to provide, personalize where permitted, measure, and protect ads. Where required, the app asks for your advertising privacy choices before requesting an ad and provides a way to revisit those choices. For more information, see Google's Privacy Policy and How Google uses information.

5. Third-Party Services and App Stores

Google processes data through its advertising and consent services as described above. The app store or platform through which you download the app may independently process download, device, or diagnostic data under its own privacy policy.

6. Children's Privacy

The app contains educational content for students. We do not ask children to submit personal information. Advertising-related data processing is described above. Parents or guardians may use the developer contact information below for questions or concerns.

7. Data Security and Retention

We do not maintain a user account database. Google manages information processed by its advertising services under its own privacy and retention practices. Advertising data is encrypted in transit by the Google Mobile Ads SDK.

8. Changes to This Privacy Policy

We may update this Privacy Policy if the app's features or data practices change. Any updated version will include a revised effective date. We encourage you to review this policy when a new version of the app is released.

9. Contact Us

If you have questions, requests, or concerns about this Privacy Policy, please use the developer contact information displayed on the app's Google Play listing.
