2. What we store
- Without an account: nothing leaves your iPhone except anonymous requests for the daily puzzle and picture packs.
- With a nickname: your nickname, a random login token (stored hashed), language, coins, solved puzzles, times, duel results, ranking positions and the time of your last activity.
- Push notifications (only if you allow them): your device push token, used to notify you about duels and rankings via Apple Push Notification service (Apple Inc.).
- Server logs: IP address and time of requests, for security and abuse prevention; they are deleted automatically on a regular basis.
- Reports: if you report a player, we store who reported whom.
Your own photos used as puzzles stay on your device and are never uploaded.
3. Purpose and legal basis
We process this data only to run the game (rankings, duels, rewards) – Art. 6(1)(b) GDPR – and to keep the service secure – Art. 6(1)(f) GDPR. Push notifications are based on your consent (Art. 6(1)(a) GDPR), which you can withdraw in the iOS settings at any time.
4. No tracking, no ads networks
Puzzle Duels uses no analytics, no advertising SDKs and no tracking. Your data is not sold or shared, except with our hosting provider (data processing agreement) and Apple for push delivery. The in-app link to listcheck24.de only opens the website in Safari; the privacy policy of that site applies there.
5. Your nickname is public
Other players can see your nickname, ranking and duel results.
6. Storage period and deletion
Data is kept as long as your account exists. In the app under ⚙️ → “Delete account” you can delete your account at any time; all related data is removed immediately.
7. Your rights
You have the right to access, rectification, erasure, restriction, data portability and objection, and the right to lodge a complaint with a supervisory authority (e.g. the Hessian Commissioner for Data Protection). Contact: batanasov257@gmail.com
8. Children
Puzzle Duels is not directed at children under 13.
