3. Advertising and Advertising Identifiers

The Service shows Google AdMob ads to remain free. AdMob may process advertising identifiers (IDFA/AAID etc.) and device information for ad serving, measurement, and fraud prevention. On iOS, tracking occurs only with your consent under App Tracking Transparency (ATT); without consent, non-personalized ads are shown. See the Google advertising policy for details. Purchasing the pass (ad removal) removes ads.

4. Third-Party Services

The Service uses the third-party services below; their handling of personal information follows each provider's own policy.

Google AdMob — advertising (policy)
Apple App Store / Google Play — in-app purchase processing and receipt verification

Game data is stored on servers operated directly by the operator.

5. Retention and Deletion

Raw usage/event logs (sessions, ad events, etc.): kept for at most 180 days from collection, then deleted or anonymized
Game records (solo/battle results) and account data: kept while the account exists; deleted without delay upon request
Aggregated/statistical data: kept in a form that cannot identify individuals

6. Your Rights

You may request access to or deletion of your information. As the Service has no sign-up, requests are handled using verification data such as your device identifier. Contact us at the address below and we will respond in accordance with applicable law.

7. Children's Privacy

The Service is not primarily directed at children under 14 and does not knowingly collect personal information from children. If we become aware that a child's information has been collected, we delete it without delay.

8. Processing by Third Parties and International Transfer

Related information may be passed to the third-party services above (Google, Apple) for advertising and in-app purchase processing, and may be processed on servers outside your country in that process.
