Privacy Policy

This policy explains what data KEEPYBOO ("the app"), operated by Bit K.K., handles and why. The app is a puzzle game; playing itself works offline, and we handle only the minimum data described below.

1. Data Stored on Your Device

Game records (scores, clear times, crowns), settings, and purchase entitlements are stored on your device. Uninstalling the app deletes this local data.

2. Cloud Backup of Game Data

To protect your progress against device loss or replacement, the app automatically backs up your game data (game records, settings, and purchase entitlements — no personal profile data) to Google Firebase (Authentication / Cloud Firestore) servers operated by Google. This backup is tied to a hashed string derived from a per-device identifier (on Android, the OS-provided app-scoped device ID; on iOS, a random value stored in the Keychain). The string stays the same after you delete and reinstall the app, so your progress can be restored. We store only the hashed string; the original device identifier is never transmitted, and we cannot connect it to you personally.

3. Account Linking (Optional)

If you choose to link a Google or Apple account in Settings > Backup & Transfer, we receive the account identifier and email address provided by Google/Apple. These are used solely to identify your backup so it can be restored on a new device, and to display which account is linked. We do not use them for advertising, do not send you emails, and do not share them with third parties.

4. Usage Statistics & Crash Reports

To improve the game, the app may send anonymous usage statistics (such as which rounds are played and cleared) and crash reports via Google Firebase (Analytics / Crashlytics). This data contains no personally identifiable information such as your name or email address. It may include the device advertising identifier, which is also used for the ads described in section 8. You can turn statistics off at any time in Settings > "Share anonymous usage stats", and you can reset or delete the advertising identifier in your device settings.

5. Third Parties & Data Location

The services above are provided by Google Firebase, which processes data on our behalf and may store it on servers outside your country of residence. We do not sell your data, and we do not share it with any third party except these processors. Google's privacy policy: https://policies.google.com/privacy

6. Permissions

The app does not request access to your camera, microphone, location, contacts, or any other personal data on your device. Network access is used only for the purposes described above.

7. Data Retention & Deletion

Local data is deleted when you uninstall the app. Cloud backup data is retained until you delete it in the app or request deletion, so your progress can be restored; if you delete and reinstall the app on the same device, the identifier above lets us reach your previous backup again (this does not apply after a factory reset or on a different device). You can delete your cloud backup and linked account data yourself at any time from Settings > Backup & Transfer > Delete your data in the app (this removes your records, settings, cloud backup and linked account, returning the app to its initial state). You may also request deletion via the contact below, and we will complete the deletion within 30 days.

8. Advertising & Purchases

The app shows full-screen video ads provided by Google AdMob at natural breaks (Retry or Next during play, Retry or Next round after clearing a round, and Retry after a game over). In addition, a video ad is shown for a hint only when you choose to watch one; you can decline. To deliver these ads, Google may process technical data such as IP address, device and app information, and general location. Ads may be personalized using the device advertising identifier. You can reset or delete that identifier in your device settings at any time; ads then become non-personalized. Where required (EEA/UK), a consent form is shown before any ad request is made and your choice there is respected. You can change your choice at any time from "Ad privacy settings" in the app settings. The app is intended for a general audience (13+) and is not directed to children. Purchasing the "remove ads" option stops all ads. Google's advertising policies: https://policies.google.com/technologies/ads

Paid content shown in the app is processed by the app store (Google Play / App Store); we do not receive your payment details.

9. Children

The app is intended for a general audience and does not knowingly collect personal data from children beyond the minimal data described above, which applies equally to all users.

10. Changes & Contact

Material changes to this policy will be announced in the app. For questions or data deletion requests, contact: contact@keepyboo.com
