OVERLIT Privacy Policy
HyuniQ ("we") provides the mobile game OVERLIT (the "Game") and processes personal information as described below.
1. Information we process
The Game has no sign-up and does not ask for your name, phone number or email address. While you play, the following is processed:
| Category | Items | How |
|---|---|---|
| Game account | Anonymous player ID (a random identifier created by the Game) | Created automatically on first launch |
| Game data | Stars per stage, in-game currency (prisms) and hint tickets, owned characters and blocks, daily check-in record, hint usage | Saved automatically while you play |
| Purchase records | Product ID, purchase time, purchase verification data (a hashed purchase token), store | When you make an in-app purchase |
| Advertising | Advertising ID, app set ID, IP address, device information, ad views and clicks | Collected by the ad SDK (Google AdMob) when an ad is shown |
| Support | Your email address, your message and, if you provide it, your player ID | When you email us |
Payment details (such as card numbers) are handled by Google Play; we never receive them.
2. Why we process it
- Saving your progress and items and keeping them available
- Verifying in-app purchases, preventing duplicate or fraudulent purchases, handling refunds
- Giving daily check-in and stage rewards
- Showing rewarded ads you choose to watch, measuring ads and preventing ad fraud
- Answering your questions
3. How long we keep it
- Game data: until you ask us to delete it or the service ends.
- Purchase records: 5 years, as required by Korean e-commerce law, then deleted.
- Support emails: 1 year after the request is resolved.
- Advertising data: kept and processed by Google under Google's policies.
4. Service providers and international transfers
| Recipient | Country | Data | Purpose |
|---|---|---|---|
| Unity Technologies (Unity Gaming Services) | United States and other countries where Unity's cloud servers are located | Anonymous player ID, game data, purchase records | Storing your game account and data, server processing |
| Google LLC (Google Play billing) | United States | Purchase information | Processing in-app purchases |

Data is sent over the network while you use the Game. If you do not want this, stop using the Game and request deletion (section 7).
5. Ads and your advertising ID
- When you choose to unlock hints with an ad, the Game shows a rewarded ad provided by Google AdMob.
- Where consent is required (such as the EEA, the UK and Switzerland), a consent screen appears on first launch, and you can change your choice at any time under Settings > Ad privacy settings.
- You can reset or delete your advertising ID and turn off personalized ads in your device settings (Google > Ads).
- How Google uses data: https://policies.google.com/technologies/partner-sites
6. Sharing
We do not share your personal information with third parties other than the service providers in section 4, unless required by law.
7. Your rights and data deletion
- You can ask to access, correct or delete your information, or to stop its processing.
- To delete your data: copy your player ID from the Game's Settings screen and email it to
hyuniqlab@gmail.comwith the subject "Data deletion request". We delete your game data without delay (within 10 days at the latest) and let you know. Purchase records that the law requires us to keep are stored separately for the period in section 3 and then deleted. - Uninstalling the Game removes data on your device, but your game data on our server remains until you request deletion.
8. Security
All communication is encrypted (TLS). Currency and purchase records can only be changed by our server, and purchases are credited only after the store's signature is verified. Access is limited to the business owner, and admin accounts use 2-step verification.
9. Children
The Game is intended for users aged 13 and over. We do not knowingly collect personal information from children under 14 (the age of consent in Korea). If we learn that we have, we delete it without delay. Parents or guardians can request deletion as described in section 7.
