This Privacy Policy explains how "밤.밤?밤!" (Bomb.Bomb?Bomb!, the "Service") collects, uses, stores, and protects your information. By using the Service you agree to this Policy. The Service is operated by 주식회사 문화와기술의만남 (the "Company").
1. Information we collect
a. Google account information — when you sign in with Google, we receive your email address, a Google account identifier (the "sub" claim), and basic profile information. We store your email, an auto-generated nickname, and the Google identifier.
b. Nickname — an editable display name (auto-generated as "Player-xxxxxxxx" on first sign-in) shown on leaderboards.
c. Gameplay data — game session data used to compute and verify scores, including a random seed, your action log, scores, and progress. This is required to prevent cheating and to operate rankings.
d. Advertising identifier — on Android, the Google Mobile Ads (AdMob) SDK initializes at app startup and may access your device's advertising identifier, even while no ads are shown. Ads are currently disabled (dormant), so no ads are displayed. There are no ads on the web version.
e. Technical data — standard server logs (e.g., IP address, timestamps) generated when your device connects to our servers.
2. How we use your information
We use your information to: authenticate you and maintain your session; operate global leaderboards; verify game results and prevent cheating; provide, maintain, and improve the Service; and comply with applicable law.
3. Storage and security
Data is stored in a PostgreSQL database hosted on Amazon Web Services (AWS) in the Seoul (South Korea) region. Access and refresh tokens (JWT) are stored in your browser's local storage on your device. Traffic is encrypted in transit (HTTPS/TLS). We apply reasonable technical and organizational safeguards.
4. Third-party services and international transfer
- Google (OAuth sign-in) — processes your Google account information for authentication.
- Google AdMob (Android, when ads are active) — processes advertising identifiers to serve ads.
These providers may process data outside South Korea. Please review Google's privacy policy for details.
5. Retention and deletion
We retain your information while your account is active. You can sign out at any time (this revokes issued refresh tokens across devices). To delete your account and associated data, see the "Account & Data Deletion" page. When you delete your account it is marked deleted and removed from public rankings at once; it is then kept for 30 days so that you can undo the deletion, and after that period the account and its game history are permanently erased (deleted, not anonymized), except where retention is required by law.
6. Children
The Service is intended for a general audience and is not directed to children under 14. We do not knowingly collect personal information from children under 14; if we learn that we have, we will delete it.
7. Your rights
You may request access to, correction of, or deletion of your personal information. Contact us at contact@mungiman.com.
8. Changes
We may update this Policy. Material changes will be announced within the Service or on this page.
