This policy explains what information the Dongle Mart app ("the app") collects, why, and how it is handled.
1. What we do NOT collect
- Name, date of birth, gender
- Email address, phone number, postal address
- Contacts, photos, camera, microphone, files
- Precise location (GPS)
- Payment information (the app has no in-app purchases)
There is no sign-up, and the app collects nothing that the user types in. The display name shown on the leaderboard is a fixed value ("동글이") that is identical for every user.
2. What we collect
2-1. Stored on the device only, never transmitted
- Per-game high scores, cumulative revenue, store level
- Coin balance, owned costumes, equipped costume
- Daily mission progress and reward claim status
- Sound and music on/off settings
Deleting the app deletes all of the above.
2-2. Collected automatically and transmitted

3. Why we collect it
- To provide game features — weekly leaderboards
- To improve the games — to find out which games are too hard or too easy and where players stop playing, so difficulty can be tuned
- To fix crashes
- To serve ads — rewarded ads that the user chooses to watch on the result screen
4. Sharing and processors
We do not sell personal information and do not share it with third parties except the service providers below.

6. Retention and deletion
- On-device data — removed as soon as the app is deleted.
- Leaderboard entries — organised into weekly boards; previous weeks are no longer shown in rankings.
- Analytics data — retained per the default retention period of Google Analytics for Firebase.
- Crash data — deleted automatically per Crashlytics policy.
7. Your choices
-
Opt out of personalised ads
Android: Settings → Google → Ads → Delete advertising ID / opt out
iOS: Settings → Privacy & Security → Tracking → turn off "Allow Apps to Request to Track" - Delete on-device data — uninstall the app.
- Request deletion of a leaderboard entry — email us. Since entries are keyed only by an anonymous identifier, please include the device you played on and the approximate score so we can locate it.
- Access, correction, or restriction — email us.
8. Children
The app is not directed to any particular age group, and we do not knowingly collect personal information from children under 14. If we learn that we have, we will delete it promptly.
9. Security
- All network traffic is encrypted with HTTPS.
- The leaderboard database is protected by access rules; a user can only modify their own entry.
- The app has no passwords, so there are no passwords to leak.
10. Changes to this policy
If this policy changes, we will post the change and its effective date on this page. Significant changes will also be announced in the app.
