1. Overview
This policy explains what information the Blast Bloom team ("we") processes when providing the mobile game Blast Bloom (the "App"), why, for how long, and your rights. We comply with applicable laws including the Korean Personal Information Protection Act and the EU GDPR.
2. Information we do not collect
- Account details such as name, email or phone number — the App has no login.
- Precise location, contacts, photos or microphone — the App does not request these permissions.
- Payment card details — purchases are handled by Google Play; the App cannot access them.
3. Information we process
| Data | Purpose | Processor |
|---|---|---|
| Anonymous installation identifier (a random value generated and stored on your device) and a linked anonymous user number | Leaderboard entry, preventing duplicate rewards, verifying campaign progress | Our server |
| Leaderboard display name (generated automatically, you can change it) | Shown publicly on weekly and endless leaderboards | Our server |
| Game records (score, waves reached, survival time, kills, cleared stages, whether a revive was used) | Ranking, reward calculation, cheat checks | Our server |
| Purchase records (product ID, purchase receipt token) | Verifying and restoring Remove Ads and chapter pass purchases | Google Play Billing + our server |
| Advertising ID, device information (model, OS version, language), IP address (may be used to estimate approximate region), ad interaction records | Serving and measuring ads, confirming rewarded ad views | Google AdMob |
Game progress (training ranks, battle records, settings) is stored on your device by default.
4. Ads and consent
The App shows Google AdMob ads (banner, interstitial and optional rewarded ads) to stay free. In the EEA, UK and similar regions, personalised-ad consent is collected through Google's User Messaging Platform, and you can change it any time in Settings > Privacy. See How Google uses information from sites or apps that use its services.
5. Retention
- Weekly leaderboard entries are deleted up to 8 weeks after the season ends.
- Anonymous identifiers, game records and purchase confirmations are kept while the service is provided and deleted promptly on request, except transaction records we must keep by law.
6. Sharing and international transfer
We do not sell your information. The data listed above may be sent to Google LLC (USA) to serve ads, and our server may run on cloud infrastructure outside your country.
7. Your rights and deletion requests
You may request access, correction or deletion of your information. Email developerdoga@gmail.com with your leaderboard display name and we will process the request. Uninstalling the App removes the data stored on your device.
8. Children
The App is not directed to children under 13 and we do not knowingly collect their personal information.
9. Changes
Changes to this policy will be posted on this page with a new effective date.
