Summary
CombDoku has no sign-up and never asks for your email, real name or precise location. To run leaderboards it creates an anonymous player profile on our servers. It uses Google Firebase and Google AdMob, and Apple’s iCloud, Keychain and Game Center. Uninstalling the app does not delete all of this; see Deleting your data.
| Data | Where it lives | Removed by uninstalling? |
|---|---|---|
| Level progress, power-ups, settings, an in-progress board, cached leaderboard and challenge history | On your iPhone | Yes |
| Completed levels, power-up inventory, streak | Your iCloud account (if iCloud is on) | No, it re-syncs |
| Player ID and its secret, profile (name, avatar, background), onboarding and purchase flags, first-launch date, streak reward day | Your iPhone’s Keychain | No |
| Public profile: display name, avatar, background, country (unless hidden), CombDoku+ badge | Our Firebase database | No |
| Leaderboard entries: points, levels cleared, lives saved, total time, last update | Our Firebase database | No |
| Daily Challenge results: score, attempts, time, when solved | Our Firebase database | No |
| A short-lived “active now” marker when you open today’s leaderboard | Our Firebase database | No |
| Anonymous per-level counts and time ranges (no player ID) | Our Firebase database | Not applicable |
| Usage events with a random install ID and app version | Google Firebase Analytics | No (kept per Google) |
| Advertising and device identifiers, ad interactions | Google AdMob | No (kept per Google) |
| Game Center achievements and score | Apple | No (your Apple account) |
On your iPhone
Your current level, power-up balances, settings (appearance, sound, haptics, reminders), any board in progress, and cached copies of leaderboard and challenge history are stored in the app’s local storage. Deleting the app removes these local files.
Keychain and iCloud
Keychain. CombDoku saves your player ID, a secret that proves the leaderboard profile is yours, your profile choices, whether you finished onboarding, a purchase flag, your first-launch date and your streak reward day in the iOS Keychain. Keychain items stay on the device after you delete the app, so a reinstall picks up your profile again.
iCloud. If iCloud is on for your Apple Account, CombDoku syncs completed levels, power-up inventory and your streak through iCloud key-value storage so they follow you between iPhones. This data is held by Apple in your iCloud account; we can’t read it. Remove it in iOS Settings → [your name] → iCloud → Manage Storage.
Anonymous player ID
When you first open CombDoku, the app signs in to Firebase Authentication anonymously. There is no email, password or sign-up. It creates a random player ID and a secret stored in your Keychain, and links the two on our server so only your app can update your profile and scores. Other apps and players can’t read the secret.
What other players see
Leaderboards are public to everyone who plays CombDoku. Any player can see your:
- display name (a fun default until you change it), avatar and background color;
- country flag, which is shown by default. It is set once from your App Store region, or your device region if that isn’t available. It is not GPS. Choose “Prefer not to show” in your profile to remove it from your public profile;
- CombDoku+ badge, if you subscribe;
- points, levels cleared, lives saved, total play time, and when your score last changed.
Don’t use your real name or anything personal as your display name. After a level, CombDoku may show “insights” such as how your time compares with others; these come from anonymous totals and appear only once a level has at least five clears.
Firebase services
CombDoku uses these Google Firebase services:
- Authentication (anonymous)
- Creates the anonymous sign-in described above.
- Cloud Firestore
- Stores your public profile, leaderboard entries, Daily Challenge results and anonymous per-level totals. Weekly and all-time boards are calculated from the daily entries on our server.
- Remote Config
- Downloads game settings such as level-pack locations, ad timing, sale windows and reward amounts. It doesn’t send your game data.
- Hosting
- Serves the downloadable level packs.
- Analytics (Google Analytics for Firebase)
- Records how the app is used: levels started, completed or failed; Hints and Reveals used; revive and rewarded-ad views; store and leaderboard screens opened; and which product was bought with a random install ID, the app version and build, and Firebase’s own app-instance ID. We use it to fix problems and improve the game. Events start only after you answer the tracking prompt, whichever choice you make.
Google processes this data under its own terms; see Firebase privacy and security.
Game Center
If you’re signed in to Game Center, CombDoku reports your achievements and your levels-completed score to Apple using your Game Center player ID. Apple manages that data under the Apple Privacy Policy; we don’t receive your Apple Account details.
Ads and tracking
CombDoku shows ads from Google AdMob: a banner on Home and the board, a full-screen ad sometimes between levels, and optional rewarded ads you choose to watch (Revive, or a free Hint or Reveal). AdMob may collect device and advertising identifiers and information about ad interactions. See how Google uses information in ads.
After the splash screen, iOS shows Apple’s App Tracking Transparency prompt: “CombDoku uses your data to show more relevant ads. You can play with non-personalized ads if you prefer.” If you allow tracking, AdMob may use your device’s advertising identifier (IDFA) to personalize ads across apps and websites. If you decline, ads are still shown but are not personalized using the IDFA. AdMob only starts after you answer. You can change this any time in iOS Settings → Privacy & Security → Tracking.
CombDoku+ and Remove Ads turn off banner and between-level ads. Rewarded ads stay optional for everyone.
Purchases and subscriptions
Purchases and subscriptions are handled by Apple through the App Store. We never see your payment card or billing details. The app learns which products you own so it can unlock them, and Analytics records which product was bought (not your payment details).
Notifications
Reminders (streak, Daily Challenge, daily leaderboard) are local notifications scheduled on your iPhone. CombDoku doesn’t use push notifications and doesn’t send your data to a notification service. Turn reminders off in Settings → Reminders or in iOS Settings.
Children
CombDoku is rated 13+ on the App Store and is not directed at children under 13. We don’t knowingly collect personal information from children under 13. If you believe a child under 13 has created a leaderboard profile, email us and we’ll delete it.
How long we keep data
Your profile, leaderboard entries and Daily Challenge results stay on our servers so past leaderboards and history keep working, until you ask us to delete them. Anonymous per-level totals are kept because they can’t be linked to you. Google keeps Analytics and AdMob data according to its own retention settings and policies. Data on your iPhone, in your Keychain and in iCloud stays until you remove it.
Deleting your data
There is no delete button in the app, and uninstalling does not remove server, Keychain or iCloud data. To delete your data:
- Server data: email hello@suenainteractive.com with the subject “CombDoku data deletion” and your display name. We will delete your profile, leaderboard entries and Daily Challenge results and confirm by email. We may ask for a screenshot of your profile to confirm it’s yours.
- iCloud data: iOS Settings → [your name] → iCloud → Manage Storage → CombDoku → delete data.
- On-device and Keychain data: delete the app to remove local files. Keychain items may remain on the device; we can’t remove them remotely.
- Game Center: managed by Apple in your Game Center settings.
- Advertising identifier: deny tracking or reset your identifier in iOS Settings → Privacy & Security.
Your choices and rights
- Hide your flag (“Prefer not to show”) or change your name and avatar in your profile.
- Allow or deny tracking in iOS Settings → Privacy & Security → Tracking.
- Turn off iCloud for CombDoku in iOS Settings to stop syncing.
- Turn off reminders in Settings → Reminders.
Depending on where you live, you may have the right to access, correct, delete or get a copy of your personal information, or to object to certain uses. Email us to make a request; we’ll respond within the time the law requires.
