One Stick: Math Challenge

Last updated: August 19, 2026

This privacy policy describes how One Stick ("the app", "we") handles information when you use the app.

Summary

• The app is a single-player math puzzle game. No account is required.
• Game progress and scores are stored only on your device and are never sent to us.
• The app uses Apple Game Center, Apple's own service, if you choose to sign in, to share your score and achievements with your Game Center friends.
• The app displays advertising served by Google AdMob. Ads are served in a non-personalized mode: the app does not collect or transmit a device identifier for advertising purposes, and ads are not targeted using your personal data.

Information we collect

Information stored on your device

The app stores your puzzle progress, scores, streaks, and preferences (such as your sound setting) locally on your device. This information never leaves your device.

Game Center

If you sign in to Game Center, your score and achievement progress are submitted to Apple's Game Center service. This data is handled by Apple in accordance with Apple's privacy policy, and you control it through your Game Center settings.

Advertising

The app uses Google AdMob to display banner and interstitial advertising. Ad requests are made with personalized advertising disabled. Google may collect limited, non-personalized information (such as general device type and coarse location) in accordance with its own privacy policy: https://policies.google.com/privacy

The app does not:

• collect your name, email address, or other contact details;
• access your location, contacts, camera, or microphone;
• track you across other apps or websites;
• sell your data.

How information is used

• Device-local data is used solely to run the game (for example, showing your progress and streaks).
• Game Center data is used to display leaderboards and achievements.
• Advertising is used to keep the app free to play.

Sharing

We do not sell or rent personal data. The only third parties that receive data in connection with your use of the app are:

• Apple (Game Center, when you sign in); and
• Google (AdMob advertising, in non-personalized mode).

Data retention and deletion

• Device-local game data remains on your device until you delete the app. Deleting the app removes it.
• Game Center data is managed by Apple. You can hide or remove your Game Center data through your Apple ID / Game Center settings.
• You can withdraw consent to advertising data processing at any time by purchasing the Remove Ads option inside the app, which disables advertising entirely.

Children

The app is a general-audience puzzle game. It does not knowingly collect personal information from children. Advertisements are served in non-personalized mode and are not targeted based on a child's data.
