Privacy Policy
Sakura Memory Game ("the Service") collects and processes personal data as described below.
1. Data We Collect & Why
| Data | When collected | Purpose | Stored on |
|---|---|---|---|
| Nickname, score, completion time | When you submit a ranking | Global leaderboard display | Firebase Realtime Database |
| Profile image (uploaded or social) | When you change your profile | Display in leaderboard | Firebase Storage |
| Social account ID, nickname, profile photo URL | When you sign in | Account identity & auto-fill profile | Google SDKs |
| Email address, password | When you create or sign in to an email account | Account sign-in & password recovery | Firebase Authentication (passwords are hashed by Firebase and never readable by the Service) |
| FCM push token | First launch (with permission) | Event & notice notifications | Firebase Cloud Messaging |
| Advertising ID (AAID), IP, ad impression/click events | When ads are shown | Ad serving and measurement | Google AdMob |
| Anonymous gameplay events (screen views, game start/finish, settings changes, etc.) — no nickname, email, or other personal data | While using the Service | Product improvement & aggregate usage statistics | Firebase Analytics (Google Analytics for Firebase) |
2. Third-Party SDKs
3. Retention & Deletion
Ranking data is deleted immediately upon user request. Uninstalling the App removes local device data (language preference, slot history, etc.). Uploaded profile images are permanently deleted from Firebase Storage when you upload a new one or request removal.
4. Your Rights
You may request access to, correction of, or deletion of your personal data at any time. Ad personalization can be controlled via your device settings ("Reset Advertising ID" or "Opt out of Ads Personalization").
5. Age Rating
The Service is playable by all ages without an account. Creating an account (social or email sign-in) requires confirming you are 14 or older; we do not knowingly collect personal data from children under 14.
