Bounce Star Privacy Policy
Effective date: October 18, 2026
momolab ("we") runs the mobile game Bounce Star (the "Game"). This policy explains what information the Game handles and why, in line with the EU General Data Protection Regulation (GDPR), the UK GDPR and the Korean Personal Information Protection Act.
1. Summary
- The Game has no sign-up or login. We do not ask for your name, email address, phone number or location.
- The Game has no ads, does not use the advertising identifier (IDFA) and does not track you across other companies' apps or websites.
- To improve the Game we analyse play records (where you fell, purchase results, errors and so on). These records carry a random device number, not your name.
- Payments are processed by Apple. We never receive your card or other payment details.
- Turning off "Data sharing" in the Game's settings stops analytics, deletes the records stored on your device and asks our analytics provider to delete what it holds.
2. Information we handle and why
| Category | Items | Purpose |
|---|---|---|
| Game save | Progress, coin and item balances, settings, purchase transaction IDs | Saving your game; never granting the same purchase twice |
| Play records | Level start, end, where and how you fell, play time, continues and item use, coin changes, popups and shop visits, settings changes | Tuning difficulty and the in-game economy; finding where players stop |
| Purchase records | Product, price and currency, result (success, cancelled, failed) | Checking revenue; finding purchase problems |
| Device and app information | Device model, OS version, app version, language and region settings, memory, screen size, frame rate, error messages | Fixing performance problems and crashes |
| Identifiers | Install number (random per install), device number (random, stored in the device keychain, kept across reinstalls) | Grouping records from the same device; measuring returning players |
| Received by the analytics provider | IP address, the provider's installation ID, identifier for vendor (IDFV) | Delivering analytics and country statistics (section 4) |
"Region" is the value of your device setting (Settings > General > Language & Region), not your location.
3. Retention and deletion
- The game save and the play record file stay on your device. The play record file is replaced roughly every 4 MB, so older records are removed. Deleting the app deletes both.
- The device number is kept in the device keychain and may survive deleting the app. Turning off "Data sharing" deletes it immediately.
- Records sent to our analytics provider (Unity) are kept for 13 months under Unity's policy and then deleted automatically. Turning off "Data sharing" sends a deletion request, and Unity deletes your records within 30 days of it.
4. Service provider and international transfer
We use the provider below to analyse play records, which means your information is transferred abroad.
| Item | Details |
|---|---|
| Recipient | Unity Technologies (Unity Gaming Services Analytics) |
| Contact | DPO@unity3d.com |
| Countries | The United States and other countries where Unity Technologies operates data centres |
| Items | The play records, purchase records, device and app information and identifiers in section 2, IP address, IDFV |
| When and how | Sent over the network while you play |
| Retention | As in section 3 (13 months; deleted within 30 days of a deletion request) |
Unity acts as our processor and handles the data on our instructions. See Unity's privacy policy at https://unity.com/legal/privacy-policy.
Apple processes payments under its own policies; we receive only the product, the price and a transaction ID from Apple.
5. Consent and objection
- If your device region is in the EU, the EEA, the UK or Switzerland (or cannot be determined), the Game asks for your permission on first launch and sends nothing to the analytics provider before you answer (GDPR Art. 6(1)(a), consent).
- In other regions we rely on our legitimate interest in improving the Game (GDPR Art. 6(1)(f)) or applicable law, and you can object at any time.
- In every region you can turn "Data sharing" off or on in Settings at any time. Turning it off stops recording, deletes the record file and the device number on your device, and asks the analytics provider to delete your records. The Game works the same with it off.
6. Your rights
You may ask to access, correct or delete your information, or to restrict its processing. Because the Game has no accounts, we cannot look you up by name; the quickest way is to turn off "Data sharing" in Settings. For any other request, contact us at the address below. Users in the EU or UK may also complain to their local data protection authority.
7. Children
The Game is not directed at any particular age group and does not ask for information that identifies a person directly, such as a name or contact details. Parents can turn off "Data sharing" in Settings to stop a child's play records from being sent.
8. Security
The device number is a random value and is never linked to your name or contact details. Data sent to the analytics provider travels over an encrypted connection (HTTPS). Only the operator can access the analytics data.
