Fominykh Maksim built the Equation Challenger app. This service is provided by Fominykh Maksim at no cost and is intended for use as is.
This page informs users about the (non-)collection, use, and disclosure of personal information in connection with the Equation Challenger app.
Information Collection and Use
Equation Challenger does not collect, store, or transmit any personal information. The app runs entirely on your device, does not require network access, and does not contain analytics, advertising, or third-party tracking SDKs.
Any data you enter in the app (for example, your answers to math problems) stays on your device and is not sent anywhere.
Third-Party Services
The app does not integrate with any third-party services that collect user information.
Advertising
The app does not contain advertising.
Cookies
The app does not use cookies.
Permissions
The app does not request any Android permissions that would give access to personal data. It does not request internet access, location, contacts, storage, camera, or microphone.
Log Data
The app does not collect or transmit log data. Crash information handled by the Android operating system itself (outside this app) is governed by your device manufacturer's and Google Play's own privacy policies.
Children's Privacy
Equation Challenger is suitable for all ages, including children under 13. Because the app does not collect personal information from any user, it does not collect personal information from children. The app complies with the U.S. Children's Online Privacy Protection Act (COPPA) and the EU General Data Protection Regulation for children (GDPR-K) by design: there is no data collection to consent to.
Security
Because no personal information is collected or transmitted, there is no user data held by Fominykh Maksim to protect.
Links to Other Sites
The app does not contain links to external sites.
Changes to This Privacy Policy
This Privacy Policy may be updated from time to time. Changes are effective immediately once posted on this page. Users are encouraged to review this page periodically.
