4. Third-party services
Our apps may use the following third-party services, which may collect information as described in their own policies. Which services apply to a given app is disclosed on that app’s Google Play Data safety section.
- Google Play Services, Google Play Games Services and Google Play Billing — policies.google.com/privacy
- Google AdMob (advertising) — policies.google.com/technologies/ads
- Firebase (analytics and crash reporting) — firebase.google.com/support/privacy
5. Advertising
Some of our free games display ads. Ad partners may use the Android Advertising ID to show ads and measure results. You can reset your advertising ID or opt out of ads personalization in your Android settings (Settings → Privacy → Ads). Where required by law, we request your consent before showing personalized ads.
6. How we share information
We do not sell your personal information. We share it only:
- With service providers acting on our behalf (hosting, analytics, advertising and payments, as listed above)
- To comply with law, legal process or governmental requests
- To protect the rights, safety and security of our users, the public or BT Computing
- In connection with a merger, acquisition or sale of assets, with notice to affected users
7. International transfers
We are based in the Republic of Korea. Our service providers may process data in other countries, including the United States. Where required, we rely on appropriate safeguards for such transfers.
8. Data retention
We keep information only as long as needed for the purposes above. Account and game data are retained while your account is active and deleted upon your request (see Account & Data Deletion). Purchase records are retained for the period required by Korean tax and e-commerce laws (generally 5 years). Support emails are retained for up to 3 years.
9. Security
We use reasonable technical and organizational measures, including encrypted transmission (HTTPS/TLS) and access controls. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.
10. Your rights and choices
Subject to applicable law (including Korea’s Personal Information Protection Act, and where applicable the GDPR and CCPA/CPRA), you may request access to, correction, deletion or restriction of your personal information, object to processing, withdraw consent, or request a copy of your data. To exercise these rights, email bert.shim@gmail.com or follow the steps in Account & Data Deletion. You may also lodge a complaint with your local data protection authority, such as the Personal Information Protection Commission of Korea.
11. Children’s privacy
Our Services are not directed to children under 13 (or under 16 where local law sets a higher age) and we do not knowingly collect personal information from them. In Korea, we do not knowingly collect personal information from children under 14 without a legal guardian’s consent. If you believe a child has provided us personal information, contact us and we will delete it promptly.
12. California and EEA/UK residents
We do not sell or “share” personal information as defined by the CCPA/CPRA for cross-context behavioral advertising except through the advertising identifiers described in Section 5, which you can control as described there. Where GDPR applies, our legal bases are performance of a contract (providing the Services), legitimate interests (security, analytics, improvement), consent (personalized ads) and legal obligation.
13. Changes to this policy
We may update this policy from time to time. The “Last updated” date above shows the latest revision. Material changes will be announced on this page or in the app.
