Effective date: 28 September 2026

This policy explains what BrainKarate does with information when you use the app. BrainKarate is a free memory-game app for Android. It is supported by advertising. There are no in-app purchases and no paid subscription.

The app is published under the package name com.brainkarate.app by the developer of github.com/codingtodecoding/brainkarate.

3. How information is used

We do not sell personal information.

4. Advertising

Ads are provided by Google AdMob. Google and its partners may use an advertising identifier, device information such as device model and language, IP address, and approximate location to deliver, measure, and limit ads. Their practices are described in Google’s privacy policy and Google’s advertising technologies policy.

You can reset or delete your advertising ID in your Android settings. You can also limit ad personalization in your Google account settings.

5. Google Sign-In

If you use Continue with Google, authentication is handled by Google. BrainKarate receives your Google account name and email address and saves them on the device. Google’s processing is covered by Google’s privacy policy. You can use Continue as guest instead.

6. Storage, retention, and deletion

Sign-in details and game progress are kept in local storage on the phone until you remove them. You can delete them by logging out, using Reset progress in the app, or uninstalling BrainKarate. Because this data is not stored on a BrainKarate server, there is no online account for us to delete.

7. Sharing

BrainKarate does not share your email, phone number, or game progress with other companies. The share button sends a score message only when you choose to share it, using the share sheet on your device.

Ad data is processed by Google as described above. If you use Google Sign-In, Google already holds the account information you use to sign in.

8. Children

BrainKarate is not directed at children under 13, and we do not knowingly collect personal information from children under 13. Do not enter a child’s email address or phone number.

9. Security

Information saved by the app stays on your device. No method of storage is perfectly secure. Protect your phone with a screen lock.

10. Changes to this policy

If this policy changes, the updated version will be posted at this page with a new effective date. Continued use of the app after the update means you accept the revised policy.
