ArithmoRush: Math Speed Challenge
Last updated: March 2026
1. Introduction
Welcome to ArithmoRush: Math Speed Challenge ("the App"), developed and published by ZanshinLab. This Privacy Policy explains how the App handles information in connection with your use of it.
We are committed to protecting your privacy. Please read this policy carefully. By using the App, you agree to the practices described in this document.
Summary: ArithmoRush does not collect, transmit, or share any personally identifiable information. All game data is stored locally on your device only.
2. Data We Collect
ArithmoRush is an offline app. The core application itself does not collect any personal data from you. Specifically, the App does not collect:
- Your name, email address, or phone number
- Your location or GPS data
- Your device identifiers beyond what AdMob requires (see Section 4)
- Photos, contacts, or files from your device
- Your browsing history or usage outside the App
- Any account registration information (no accounts required)
3. Local Data Storage
The App uses your device's local storage (browser localStorage / WebView storage) to save game progress. This data is stored exclusively on your device and is never transmitted to any server. Data stored locally includes:
- Your best score and game statistics
- Your selected difficulty level
- Your daily streak count and last play date
- Your personal leaderboard (top 10 scores)
- Total correct and wrong answers (lifetime)
This data remains on your device. You can clear it at any time by clearing the App's data through your device's Settings > Apps > ArithmoRush > Clear Data.
4. Third-Party Services – AdMob (Google)
ArithmoRush is a free app supported by advertising. The App uses Google AdMob, a mobile advertising service provided by Google LLC, to display advertisements.
AdMob may collect and use certain data to serve personalized or non-personalized ads. This may include:
- Your device's Advertising ID (a resettable identifier used for ad targeting)
- General device information (operating system version, screen size)
- IP address (used for general location, e.g., country level)
- Ad interaction data (which ads were shown, clicked)
This data is collected by Google AdMob and is governed by Google's Privacy Policy. ZanshinLab does not directly access or store this advertising data.
For more information about how Google uses data, please visit:

To opt out of personalized advertising, you can reset or limit your device's Advertising ID through your device's Settings > Google > Ads.
5. Andromo Platform
This App is built using the Andromo app-building platform. Andromo may collect certain technical information for app distribution and analytics purposes. Their data practices are governed by Andromo's own Privacy Policy, available at www.andromo.com.
6. Children's Privacy
ArithmoRush is designed to be safe and enjoyable for users of all ages, including children. The App itself does not knowingly collect any personal information from children under the age of 13 (or applicable age in your jurisdiction).
Please note that the advertising served through Google AdMob may be adjusted based on the app's content rating settings. We have configured the App to request non-personalized or age-appropriate ads in compliance with the Children's Online Privacy Protection Act (COPPA) and Google Play's Families Policy where applicable.
If you are a parent or guardian and believe your child has provided personal information to us, please contact us at the address below and we will take steps to remove that information.
7. Data Security
Since ArithmoRush does not transmit personal data to any server, there is no risk of a server-side data breach affecting your personal information. All locally stored game data is protected by your device's own security mechanisms.
8. International Users
ArithmoRush is available worldwide. The App does not transfer your personal data across borders, as all game data is stored locally on your device. Advertising data collected by Google AdMob may be processed in the United States or other countries where Google operates, subject to Google's Privacy Policy.
9. Changes to This Privacy Policy
We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated "Last updated" date at the top. We encourage you to review this page periodically. Continued use of the App after changes constitutes your acceptance of the updated policy.
