🔐 Privacy Policy – FormulaSphere

This Privacy Policy explains how FormulaSphere handles user information.

FormulaSphere is designed as an offline formula reference and calculation application. We respect your privacy and aim to keep the app simple and privacy-friendly.

1. Information We Collect

FormulaSphere does not require users to create an account and does not intentionally collect personally identifiable information.

The app does not require you to provide:

• Name

• Email address

• Phone number

• Password

• Home address

• Payment information

• Account credentials

2. Internet Connection

FormulaSphere is designed to provide its core functionality offline.

The formula library, calculators, search, favorites, recently viewed formulas, and other core features do not require an internet connection.

3. Local Data Storage

Some app preferences and user-created data may be stored locally on your device using local storage.

This may include:

• Favorite formulas

• Recently viewed formulas

• Theme preferences

• App settings

This information remains on your device and is not intentionally transmitted to our servers.

4. Personal Information

FormulaSphere does not intentionally collect or sell personal information.

The app does not require registration or login to use its core features.

5. Third-Party Services

FormulaSphere does not intentionally use third-party analytics, advertising SDKs, tracking services, or external APIs for its core functionality.

6. Children's Privacy

FormulaSphere is an educational/reference application and does not knowingly collect personal information from children.

Because the app does not require an account or personal information for its core functionality, users can use the application without submitting personal details.

7. Data Security

Because user preferences and certain app data are stored locally, users should understand that the security of locally stored information also depends on the security of their device.

We recommend keeping your Android device protected with an appropriate screen lock and current security updates.

8. Data Deletion

Since FormulaSphere does not require an online account, there is no online user account to delete.

Locally stored app information such as favorites, history, and preferences can generally be removed by clearing the app's data or uninstalling the application from the device.

9. Changes to This Privacy Policy

We may update this Privacy Policy if the app's functionality or privacy practices change.

Any updated version will include a revised "Last Updated" date.

10. Contact

If you have questions, feedback, or concerns regarding this Privacy Policy or FormulaSphere, please contact the developer through the contact information provided on the application's official Google Play listing.
