Privacy Policy
Upcoming change — version 1.1 takes effect on 22 October 2026, covering paid items and advertising. Read the revision
This policy was written in Korean. If the two versions differ, the Korean version prevails. Read the Korean version.
majunolja ("the studio") handles your information carefully and follows the Personal Information Protection Act of the Republic of Korea. This policy applies to GEMPIRE ("the service").
The service does not ask for your real name, email address, or phone number. There is no sign-up step. An account is created from an identifier generated on your device the first time you open the app.
1. What we collect
1.1 Stored on our servers
| Area | Items |
|---|---|
| Account | Device identifier, account identifier, nickname, avatar, language, join time, last seen time, app version |
| Matches | Match results (seat, rank, points, card and noble counts), rating and its changes, match replays |
| Progress | Experience, games, wins, streaks, achievement progress, owned items |
| Safety | Reports (reporter, target, reason), block lists |
| Session | Authentication tokens and their expiry |
The device identifier is not an advertising identifier. It is the per-app identifier Android provides. We do not read advertising identifiers (AAID/IDFA).
1.2 Stored only on your device
Display, sound, accessibility and gameplay settings, and tutorial progress, stay on your device and are never sent to our servers. They are removed when you uninstall the app.
1.3 Sent but not stored
We do not store IP addresses. To limit excessive requests we count them in memory for a short window and forget them afterwards. They are never written to disk or to logs.
1.4 What we never collect
Email addresses, real names, phone numbers, postal addresses, dates of birth, location, contacts, photos, voice, advertising identifiers, and payment instrument details.
2. How we collect it
Information is generated automatically as you open the app and play. Your nickname and avatar are values you enter or choose. There are no collection forms and we receive nothing from third parties.
3. Why we use it
- Running the service — identifying accounts, matching opponents, calculating ratings and rankings, keeping progress and owned items
- Safety — handling reports, applying blocks, preventing abuse
- Quality — diagnosing errors and improving the service
We do not use it for advertising or marketing.
4. How long we keep it
| Item | Period |
|---|---|
| Account, rating, progress, owned items | Until the account is deleted |
| Match replays | 30 days (kept longer if subject to a report) |
| Reports | 1 year |
| Authentication tokens | 30 days |
| Backups | 30 days |
| Match results | Kept in anonymised form (see section 7) |
5. Sharing with third parties
We do not share personal information with third parties. We do not sell it or pass it on for advertising. We comply with lawful requests from authorities where required by law.
6. Processors
| Processor | Purpose | Location |
|---|---|---|
| Amazon Web Services | Hosting and storage | Republic of Korea (Seoul) |
Data is stored in Korea. No personal information is currently transferred abroad.
7. Deletion
When you delete your account:
- Immediately — sign-in is blocked and active sessions end.
- Immediately — your nickname is replaced with an anonymous label and the link between your device and the account is removed.
- Retained — match results remain as an anonymous participant.
- Retained — reports remain for one year.
Why match results are not erased. Removing one player's record would corrupt the history of everyone else who played that game. We strip identifying information and keep only the seat and the result.
Why reports are kept. Otherwise someone could report another player and then delete their account to erase the trace, and repeat reports could not be counted.
Deletion cannot be undone. The link between your device and the account is removed, so opening the app again on the same device creates a new account. Previous results, rating, achievements and owned items cannot be restored.
8. Your rights
You may request access, correction, deletion, or suspension of processing at any time.
- Access and correction — your nickname and avatar can be viewed and changed in the app's profile screen.
- Deletion — use the account deletion request page, or contact us below.
- Suspension of processing — contact us below.
We respond within 10 days of receiving a request. A legal representative may make a request on your behalf.
9. Security
- All traffic between the app and our servers is encrypted (TLS).
- Internal service ports are never exposed to the internet.
- Access to data is limited to operations staff.
- Backups are kept separately from the primary data.
10. Children
Where we process the information of a child under 14, we obtain consent from a legal representative. The service collects no real names or contact details.
