Privacy Policy
Last updated: October 15, 2026
Hyeji Choi (the “Operator”) processes information needed for Bubble Bubble sign-in, rankings, advertising and support as described below.
1. Information and purposes
- Account information: Account identifiers, email addresses (including Apple private relay addresses) and available display names received through Apple or Google sign-in are used for authentication and account management. The app does not receive or store your social account password.
- Profile and rankings: Your chosen player name, country, best score and achievement time are shown on the global leaderboard. Other users, including guests, can view rankings. Email addresses are not shown in rankings. You can change or clear your country selection.
- Game verification: For signed-in players, game identifiers, start times, board dimensions and gameplay data such as bubble drop positions and timing are used on the server to verify scores and prevent abuse.
- On-device storage: Recent play records and your best score are stored on your device. Information stored only on your device may not be recoverable if app data is cleared.
- Play balance and rewards: The server processes remaining plays, refill times, game starts and ad reward records linked to your signed-in account or an anonymous guest identifier. An opaque reward reference is shared with the ad provider; your email and player name are not. Reward records are deleted after 30 days or when the associated account is deleted.
- Advertising and technical information: Google AdMob and Firebase may process IP addresses, device and app identifiers, ad impressions, viewing and interaction information, and error and performance information to provide their features and maintain security. An approximate region may be inferred from your IP address. The app does not request GPS location permission.
- Support: Your contact email address and the information you send are used to resolve your inquiry. Please do not send passwords, verification codes or payment card information.
2. External services and international processing
Apple and Google provide social sign-in; Google Firebase provides authentication, databases and server functions; and Google AdMob provides optional rewarded ads and privacy consent screens. The Operator and service providers process information as needed for these features. Server verification uses Google Cloud's US Central region. External services may process information in the United States or other countries outside your country of residence.
See the Apple Privacy Policy, Google Privacy Policy and Firebase privacy information for details of their processing.
3. Advertising and choices
The free app shows a banner ad below the game board and hides it on sign-in, account, ranking and result screens. Viewing or tapping a banner does not add plays.
A rewarded ad is requested when you choose “Watch Ad · +1 Play”. Finishing the ad adds 1 play, up to the maximum you can hold. You can also play using hourly refills without watching ads. Depending on your region, Google's consent screen may appear. Where changes are required, you can update your choices through “Information → Ad Privacy Settings” in the sign-in/account dialog. The app requests non-personalized ads, but information may still be processed to deliver ads, manage frequency and prevent abuse.
4. Retention and deletion
Accounts, profiles, rankings and game verification records are retained to provide the service and are removed from the production server when you delete your account. Once deletion starts, the server continues processing even if you close the app. Temporary account identifiers and processing status used to prevent old sign-in tokens from recreating records become eligible for automatic deletion 24 hours after account deletion completes. Actual removal may take additional system processing time.
Materials managed by service providers, such as Firebase authentication logs and backups, follow separate retention schedules. Firebase states that authentication information may take up to 180 days after a deletion request to be removed from live and backup systems. Support inquiries are retained as needed after resolution; you may request their deletion.
5. Your choices and rights
You can play as a guest without social sign-in. Starting a new game and checking plays or ad rewards require an internet connection. Signing in lets you join the global leaderboard. In My Account, you can edit your player name and country or delete your account.
To delete your account: Open Account at the top right of the game screen → Delete Account → confirm your identity. Deleted records cannot be recovered. If you are told that disconnecting Apple failed, also remove Bubble Bubble in your Apple Account's “Sign in with Apple” settings. To remove local records on other devices, clear the app data on those devices.
For access, correction, deletion or other questions about personal information processing, use the contact details below. We may ask you to confirm your identity to process your request.
6. Protection and policy changes
Authentication and access rules are applied, and public rankings do not show account contact information such as email addresses. Changes to this policy will be reflected in this page's content and revision date.
