Puzzle of the Day (Turkish: "Günün Bulmacası", the "App") processes only the data needed for the game to work. There is no sign-up or login; your account is created anonymously with a random identifier generated on your device.
1. Data we process
| Data | Why | Required |
|---|---|---|
| Random device identifier (only a one-way hash is stored on the server) | Anonymous account; linking your results to you | Yes |
| Nickname | Shown on leaderboards | No |
| Country (from your device's region setting) | Country leaderboard | Yes |
| Time zone offset | Starting each day's puzzles at your local midnight | Yes |
| Game results (date, mode, time, hints and moves), points, streak | Leaderboards, points, streaks and statistics | Yes |
| Constellation progress and archive results | Game progress | Yes |
| Friends list (players added with a friend code) | Showing friends' progress and the friends leaderboard | No |
| Usage events (app open, puzzle start/finish, hint, share, ad shown; session id, app version) | Aggregate measurement to improve the App | Yes |
| Technical logs (IP address, request time) | Security and abuse prevention | Yes |
| Device diagnostics (platform, model, OS version, phone/tablet classification or estimate, and a hash of a random installation-scoped code) | Diagnose device-specific issues and understand gameplay flows | Yes |
We do not collect your name, e-mail, phone number, location, contacts or photos. Your friends only see your nickname, country, today's solve status, streak, points and constellation progress.
2. Advertising
The App shows ads through Google AdMob. AdMob may process data such as your device's advertising ID to show and measure ads, according to Google's Privacy Policy (details). Rewarded ads are shown only when you choose to watch one. Users in the EEA, UK and Switzerland are asked for consent before personalized ads. You can reset your advertising ID or opt out of personalized ads in your device settings.
3. Legal basis
Performance of a contract (providing the game) and legitimate interests (security and improving the service). Where required (e.g. under the GDPR or Turkey's KVKK), consent for personalized advertising is requested.
4. Sharing
We do not sell your data or share it with third parties for marketing. Data is stored on a server rented for the App. Advertising data is processed by Google.
5. Retention
Your data is kept while your account exists. When you delete your account, all personal data is deleted immediately and disappears from database backups automatically within 14 days. Technical logs are kept briefly in size-limited rotating logs.
6. Your rights and account deletion
You can exercise your rights (access, correction, deletion, objection) by writing to cany96767@gmail.com. You can delete your account and all your data instantly in the App: Profile & settings → Delete account. See account deletion for other options.
7. Children
The App is intended for a general audience aged 13 and over and does not knowingly collect personal data from children under 13.
8. Changes
If this policy changes, the update will be published on this page and, where necessary, announced in the App.
