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 |
| Google Play Games link | Google Play Games player ID (used only to link your game account) | Automatically if you are signed in to Google Play Games on the device, or Settings > Google Play Games > Link |
| Game data | Stars per stage, in-game currency (prisms) and hint tickets, owned characters and blocks, daily check-in record, hint usage, coupons used, items given by us | 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 |
| Error reports | Crash and error logs, device model, OS and app version, an installation ID (a random ID created for each installation) | Sent automatically when the Game crashes or an error occurs |
| Support | Your email address, your message and, if you provide it, your player ID | When you email us |
| Playground (user maps) | Maps you make and publish (layout and map name) and when they were published, your maker number (a 4-digit number made from your player ID), plays, clears and likes per map, the maps you played, cleared, liked or reported and the report reasons, makers you blocked, whether you agreed to the publishing rules | When you publish a map, or play, like, report or block someone else's map |
Payment details (such as card numbers) are handled by Google Play; we never receive them. The Game does not use or store your Google Play Games nickname or profile picture.
What other players can see: maps you publish in the Playground, their names, your maker number and each map's likes, plays and clears. Your player ID and other information are not shown. Please don't put personal details such as a name, phone number or address in a map name. Maps you make but don't publish stay on your device and are not sent to our server.
2. Why we process it
- Saving your progress and items and keeping them available (with Google Play Games linked, also after reinstalling or on a new phone)
- Verifying in-app purchases, preventing duplicate or fraudulent purchases, handling refunds
- Giving daily check-in, stage and coupon rewards, and compensation after support requests
- Showing rewarded ads you choose to watch, measuring ads and preventing ad fraud
- Finding the causes of crashes and errors and improving stability
- Answering your questions
- Running the Playground: publishing and sharing maps, popular and new map lists, clear and like rewards, preventing abuse (repeated likes, joke reports), handling reports and hiding or removing inappropriate maps and names
3. How long we keep it
- Game data and your game account (including the Google Play Games link): until you delete it in the Game, 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.
- Error reports: kept for Unity's service retention period, then deleted.
- Playground: published maps are kept until you delete them or use "Delete my data"; then the map and its name are deleted right away (only the share code is kept so it is never given to another map). Records of maps we removed for breaking the rules are kept for 1 year to prevent repeat abuse and handle appeals. Report alert emails are kept for 1 year after they are handled.
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, Google Play Games player ID (if linked), game data, purchase records | Storing your game account and data, server processing |
| Unity Technologies (Unity Diagnostics) | United States and other countries where Unity's cloud servers are located | Error reports (section 1) | Analyzing crashes and errors |
| Google LLC (Google Play billing) | United States | Purchase information | Processing in-app purchases |
| Google LLC (Google Play Games) | United States | Google Play Games sign-in information | Sign-in and linking your game account |
| Google LLC (Google AdMob) | United States | Advertising ID, app set ID, IP address, device information, ad interactions | Serving and measuring ads, fraud prevention |
| Google LLC (Google Apps Script, Gmail) | United States | For a map with 5 reports: share code, map name, maker number, first 8 characters of the player ID, report counts by reason | Sending us a report alert email |
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.
- Delete in the Game: tap Settings > Data > Delete my data. Your game data on our server, your game account (including the Google Play Games link), your published maps and the data on your device (including the maps you made) are deleted right away. This can't be undone, including purchased items.
- Delete a published map only: in Playground > My Maps, tap the map's × button. It is deleted from our server and its code and link stop working.
- Request by email: open Settings > Support > Player ID > Copy and email it to
hyuniqlab@gmail.comwith the subject "Data deletion request". We delete your data without delay (within 10 days at the latest) and let you know. - Either way, purchase records that the law requires us to keep are stored separately for the period in section 3 and then deleted.
- Uninstalling the Game does not delete your game data on our server. Use "Delete my data" or keep your player ID before uninstalling. If you linked Google Play Games, reinstalling connects you to the same data, so you can delete it then.
- Information in your Google Play Games profile itself is managed in your Google Account's Play Games settings.
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. Only operator accounts registered on the server can give items, and every grant is logged. 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.
