Privacy Policy

Effective October 29, 2026. Number Grid : Math Puzzles does not require an account and keeps your puzzles on your device. It shows rewarded video ads through Google AdMob, which collects some information as described below.

Information stored on your device

Your settings, solved puzzles and progress remain locally on your device. We cannot access this information, and it is removed according to your device and app-uninstallation settings.

Advertising and data collection

Our app uses Google AdMob to display rewarded video advertisements. AdMob may collect certain information, including device identifiers, advertising data, IP address, approximate location, ad views, clicks, and diagnostic or performance information, to serve ads, measure ad performance, prevent fraud, and improve advertising services. Depending on your device settings, consent choices, and applicable laws, ads may be personalized or non-personalized. Google may process this information in accordance with its own privacy policy. For more information, please review Google’s Privacy Policy and How Google uses information from sites or apps that use its services.

Your advertising choices

You can reset your device’s advertising ID or turn off personalized ads at any time in your device’s privacy or ads settings. Where the law requires it, the app asks for your consent before personalized ads are shown.

No other data collection

Apart from the advertising described above, Number Grid does not collect, store, transmit or share personal information or analytics. We do not receive the information AdMob collects, and we do not sell your data.

Children

Number Grid is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.

Support emails

If you choose to email us for support, we receive the email address and information you voluntarily include in that message. It is used only to answer you and is not collected through the app.

Changes to this policy

If Number Grid’s data practices change, we will update this policy and its effective date before those changes take effect.
