Minesweeper Privacy Policy
Sungha Shin ("we") handles personal information in the Minesweeper app (the "app") as described below.
1. Information we collect and why
| Information | Purpose | How |
|---|---|---|
| Nickname | Identifying your account, showing it in the game | Entered when you sign up |
| Install ID (a random value the app creates) | Identifying your account, preventing duplicate sign-ups | Generated automatically |
| Country code (from device settings) | Statistics by country | Collected automatically |
| Operating system (iOS or Android) | Player statistics by operating system | Collected automatically |
| App version | Checking at launch whether an update is required (not stored) | Sent automatically |
| Game records (Daily Challenge records, Free Play statistics) | Keeping your records, Daily Challenge rankings | Created automatically as you play |
| Server access logs (IP address, request time) | Running the service, handling outages and abuse | Collected automatically |
| Support emails (your email address, your message, and the app version, bundle, device and OS version, nickname and user ID filled in beforehand) | Reading and answering your inquiry | When you use Settings > Contact us or write to us directly |
We do not collect your name, phone number, precise location, contacts or photos. We receive an email address only when you send us a support email. You can edit or delete the information filled in beforehand before sending.
2. Advertising
The app shows rewarded ads from Google AdMob, only when you choose to watch one: to retry a Daily Challenge, or to replay the same board in Free Play. Google may collect the following directly to serve ads, measure their performance and prevent fraud:
- Device identifiers such as the advertising ID
- IP address and the approximate location estimated from it
- Ad views and app usage
- Diagnostics
We do not give Google your nickname or game records. For details, see how Google uses information in advertising.
Your choices
- Where consent is required, such as the European Economic Area, the United Kingdom and Switzerland, the app asks for your consent to the use of ad data. You can change it at any time in Settings > Ad privacy settings.
- On iOS, the app asks whether to allow tracking. Declining makes no difference to the game, and you can change it in iOS Settings.
- On Android, you can reset or delete your advertising ID in the device settings.
3. Retention and deletion
- We keep account information and game records until you delete your account, except that Daily Challenge records remain anonymously as described below.
- We keep server access logs for 90 days and then delete them.
- We keep support emails for one year after we finish answering them and then delete them.
- You can delete your account yourself in the app: Account screen (the nickname button at the bottom of the main screen) > Delete account. Your account on the server, sign-in information, Free Play statistics and the app's data on your device are deleted immediately, and this cannot be undone. See Deleting your account for details.
- Daily Challenge records are kept in a form that no longer identifies you. Daily Challenge rankings are public to all players, so leaving should not change other players' ranks. Your nickname, install ID and country code are erased. What remains for each round is only the date, number of attempts, number of clears, best time and its medal grade, the ranked record (time, which attempt it was, score with penalty, time the server received it, final rank), a flag for suspicious records, and the sequence number and update time of the last result applied. In rankings it appears as "Deleted user".
- If you cannot use the app, contact us at the address below. Once the app is deleted we cannot easily confirm who you are, so please include your nickname.
4. Sharing and processors
| Recipient | What | Location |
|---|---|---|
| Google LLC (AdMob) | The advertising information in section 2 | United States and other countries |
| Amazon Web Services (servers, database) | Storage of the information in section 1 | Republic of Korea (Seoul, ap-northeast-2) |
| Google LLC (Google Workspace email) | Storage of the support emails in section 1 | United States and other countries |
5. Children
The app is not directed at children, and people under 14 may not use it. If we learn that we have collected information from someone under 14, we delete it.
6. Your rights
You may ask to access, correct or delete your information, or to stop its processing. Depending on where you live, you may have additional rights under local law.
7. Security
Data is encrypted in transit. Sign-in tokens are stored on the server only as hashes, and on your device in the Keychain or Keystore.
