Privacy Policy

Version 1.1 · Takes effect 22 October 2026

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").

1. What we collect

1.1 Stored on our servers

Linking an account does not store your email. The provider sends one, but all we need to join the accounts is the opaque identifier, so we receive the rest and discard it.

We never receive payment instrument details. Card numbers and the like are handled by the store; we receive only the transaction identifier and the product.

1.2 Processed for advertising

While ads are shown in the service, an advertising identifier is passed to the ad provider. The studio does not store it.

There are two ways to turn ads off.

• Personalised ads only — you can delete your advertising ID or opt out of personalised ads in your device settings. Ads still appear, but are no longer chosen by interest.
• All ads — buying Remove ads in the in-app shop stops ads appearing, and no advertising identifier is passed on any more.

1.3 Stored only on your device

Display, sound, accessibility and gameplay settings, tutorial progress, and the values used to pace how often ads appear stay on your device and are never sent to our servers. They are removed when you uninstall the app.

1.4 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.

1.5 What we never collect

Email addresses, real names, phone numbers, postal addresses, dates of birth, location, contacts, photos, voice, 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. Linking an account and making a purchase happen only when you start them yourself.

3. Why we use it

• Running the service — identifying accounts, matching opponents, calculating ratings and rankings, keeping progress and owned items
• Purchases — verifying payment, preventing duplicate grants, restoring purchases, handling refunds
• Advertising — showing ads and pacing how often they appear
• Safety — handling reports, applying blocks, preventing abuse
• Quality — diagnosing errors and improving the service

We do not use it for marketing and we do not sell personal information.

4. How long we keep it

Purchase records survive account deletion. We cannot erase them while the law requires them to be kept. In that case they are held separately from the account and used only for the purpose the law prescribes.

5. Sharing with third parties

We do not sell personal information. Information is passed on in the following cases.

We comply with lawful requests from authorities where required by law.

6. Processors

Service data is stored in Korea. Payment and advertising are processed outside Korea through Google's infrastructure.

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 links to your device and any external account are removed.
• Immediately — owned items are lost.
• Retained — match results remain as an anonymous participant.
• Retained — reports remain for one year.
• Retained — purchase records remain, separately from the account, for the period the law prescribes (section 4).

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 Settings → Account → Delete account in the app, or the account deletion request page.
• Opting out of personalised ads — delete your advertising ID or opt out in your device settings.
• 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.
• Payments are verified by our server against the store. A receipt sent by the app alone grants nothing.

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.

A purchase requires the consent of a legal representative. A payment made by a minor without that consent may be cancelled.

Ads are restricted to the general audience content rating.

12. Where to get help

In Korea you may contact the Personal Information Dispute Mediation Committee (1833-6972, kopico.go.kr) or the Privacy Infringement Report Centre (118, privacy.kisa.or.kr).

13. Changes to this policy

We announce changes on this page 7 days before they take effect, and 30 days before if the change is unfavourable to users. Earlier versions remain available.
