1. Information We Collect or Process
We may collect or process the following information to the extent necessary to provide the Service.
Some settings, such as BGM, sound effects, and vibration settings, are stored on the device.
- Email address, player name, and information required for authentication
- Friend ID, friend requests, friend relationships, and other friend-feature information
- Game type, scores, wins/losses/draws, win streaks, match history, rankings, and other game data
- Temporary identifiers used for guest play
- IP address, app version, device/OS/network information, access times, error information, and diagnostic information
- Inquiry content and information needed to handle support requests
2. Purposes of Use
We use collected information for account authentication, matchmaking, game operation, friend features, rankings and records, prevention of abuse, security, troubleshooting, service improvement, customer support, and advertising delivery and measurement.
3. Information Shown to Other Users
Player names, ranking results, Friend IDs, and similar information may be shown to other users in rankings, friend requests, friend lists, match screens, and other Service features. Share your Friend ID only as needed with people from whom you want to receive friend requests.
4. Advertising Services
The Service may use Google AdMob (Google Mobile Ads SDK) to deliver advertising. For ad delivery, measurement, and fraud prevention, Google may process IP addresses, device or account-related identifiers (which may include advertising identifiers), in-app activity, diagnostic information, and other information needed for advertising.
For information about how Google handles data, please see the Google Privacy Policy.
5. Official Website Analytics
The official website aggregates information such as page views and device types. We do not store raw IP addresses in the analytics table; instead, we use a hash that changes daily to estimate unique visits.
6. External Service Providers
We may entrust processing to external service providers, or data may be transmitted to them, as necessary for operation of the Service, infrastructure, email delivery, advertising, and other functions. We may also disclose information when required or otherwise permitted by law.
7. Security
We take measures such as verification-code expiration, sending limits, server-to-server authentication, and access controls to help prevent unauthorized access, leakage, and tampering. However, no internet-based service can guarantee complete security.
8. Retention and Deletion
We retain information for a reasonable period necessary for operating the Service, maintaining security, meeting legal obligations, and other stated purposes. After account deletion is completed, we delete profile data, authentication data, records, match history, friend requests, friend relationships, and other data directly linked to the account. Records required by law or for security may be retained for the necessary period.
9. Changes to This Policy
We may revise this Policy in response to changes in the Service, external services, laws, or other circumstances. Important changes will be announced through this site, the app, or another appropriate method.
