Privacy Policy - English
1. Introduction
Infinity Math is a mathematics learning application that provides thousands of practice questions covering topics from basic arithmetic to advanced mathematics, including calculus, linear algebra, probability and statistics, and complex analysis.
This Privacy Policy explains how Infinity Math handles information. It is intended to comply with Google Play Developer Policy, Google Play Data Safety requirements, the General Data Protection Regulation (GDPR), and widely accepted international privacy policy standards.
2. Information We Collect
The current version of Infinity Math does not collect, transmit, sell, share, or otherwise process personal information from users.
In the current version, Infinity Math:
- does not require user registration or login;
- does not collect names, email addresses, phone numbers, account identifiers, or profile information;
- does not collect IP addresses, Android ID, Advertising ID, Device ID, precise location, or other personal identifiers;
- does not request sensitive permissions such as location, camera, microphone, contacts, SMS, or external storage access;
- does not use third-party advertising SDKs;
- does not show advertisements;
- does not include memberships, subscriptions, or in-app purchases.
3. Local Learning Data
Infinity Math may store learning-related data locally on the user's device, such as practice history, learning progress, incorrect-answer records, and similar app usage records. This information is used only to provide app functionality to the user.
Local learning data is not uploaded to Zhuosang, any server, or any third party by the current version of the app.
4. How We Use Information
Because the current version does not collect personal information, Zhuosang does not use personal information for analytics, advertising, profiling, marketing, user tracking, or account management.
Locally stored learning data is used only within the app to support features such as progress display, practice continuity, and review of incorrect answers.
5. Data Storage
All learning records in the current version are stored only on the user's local device. The app is designed to function completely offline.
6. Data Retention and Deletion
Locally stored learning records remain on the user's device unless the user clears the app data or uninstalls the app. When the app is uninstalled, local app data is automatically deleted by the Android operating system.
Because the current version does not collect or store user data on external servers, Zhuosang does not maintain a server-side user database from which personal data must be deleted.
7. Third-Party Services
The current version of Infinity Math does not integrate third-party advertising, analytics, cloud synchronization, payment, login, or leaderboard services.
Future versions may add features such as Google Sign-In, online leaderboards, cloud synchronization, Google AdMob advertising, or Google Play Billing. If any future feature involves collection, use, sharing, or other processing of personal information, this Privacy Policy will be updated before the feature is launched, and user consent will be requested where required by applicable law and platform policy.
8. Children's Privacy
Infinity Math is a general mathematics learning app. The current version does not knowingly collect personal information from children or from any other users.
If you believe that a child has provided personal information to Zhuosang through Infinity Math, please contact us at animemomoovo@gmail.com. If such information is found, reasonable steps will be taken to delete it.
9. Data Security
Since the current version stores learning records only on the user's device and does not transmit personal information to external servers, risks associated with network transmission and server-side storage are minimized.
Users are responsible for maintaining the security of their own devices, including device lock settings, operating system updates, and app installation choices.
10. Your Rights
Depending on your location, including if you are in the European Economic Area or another jurisdiction with privacy laws, you may have rights such as the right to access, correct, delete, restrict, or object to the processing of personal data.
In the current version, Infinity Math does not collect or store personal information on Zhuosang-controlled servers. You can delete locally stored app data by clearing the app data in Android system settings or uninstalling the app.
For privacy-related questions or requests, contact animemomoovo@gmail.com.
11. International Users
Infinity Math is currently designed for offline use and does not transfer personal information internationally. If future online features are introduced, any related data transfers will be described in an updated version of this Privacy Policy.
12. Changes to This Privacy Policy
Zhuosang may update this Privacy Policy from time to time to reflect changes in the app, legal requirements, or platform policies. Any updated version will be posted on this page with a new effective date.
If future features involving personal information are introduced, this Privacy Policy will be updated before those features become available, and consent will be obtained where required.
