Privacy Policy
MintC Inc. ("we", "us") operates the mobile game Court Stratagem (Korean title: 왕관의 수; the "Game"). This policy explains what information we handle when you play.
1. Summary
- You start playing without signing up. We do not ask for your name, email address, phone number or date of birth.
- On first launch our server creates an anonymous account. Your game progress, purchase records, ad reward records and ranking records are tied to it.
- The only ads in the Game are rewarded ads you choose to watch. They are served by Google AdMob, whose SDK collects some information, such as the advertising identifier, directly from your device.
- You can delete your account and data at any time in the Game (Settings → Account → Delete account) or on the web: https://courtstratagem.mintcinc.com/delete-account/
- The Game is not directed to children under 13 (under 14 in Korea; under 16 where local law sets that age for consent).
2. Information we collect and why
All of it is generated automatically as you play.
| Information | Why we use it | How long we keep it |
|---|---|---|
| Anonymous account ID and a random install ID created on your device | To recognise you without a login screen and keep your progress, purchases and rewards on one account | Until you delete your account |
| Your Game Center or Play Games player ID, only if you connect it | To recover your account after reinstalling or changing devices | Until you delete your account or the link is moved |
| Game progress (stages cleared, level, stats, outfits owned, gold, items, quest and attendance records) | To provide the Game and restore your progress | Until you delete your account |
| A ledger of gems earned and spent | To keep your balance correct and handle refunds and disputes | Until you delete your account |
| Purchase records (store, transaction ID, product ID, time, granted or refunded) | To verify payments, prevent double grants, restore purchases and process refunds | 5 years from the purchase, as transaction records required by law; if you delete your account they are kept without a link to it |
| Ad reward verification records (a one-time value, the time the view was confirmed, the reward) | To confirm a completed rewarded ad, grant the reward and apply daily limits | Until you delete your account |
| Ranking records (Daily Formation time and wrong moves, weekly league points) and a display name generated by our server | To run the leaderboard and the weekly league | Until you delete your account |
| Usage events (first open, sessions, stage results, outcome of purchase and ad attempts, network timing) | To tune difficulty and service quality (our own analytics) | 180 days |
| Time zone, country (two-letter code), app version, operating system | Rewards and limits by your local day, league grouping, unsupported-version notices | Until you delete your account (request logs: 14 days) |
| If you email us: your email address, your message and your player number | To answer you and process deletion requests | 1 year after the request is closed |
- Other players see only the server-generated name and your records on the leaderboard. There is nowhere in the Game to type a name or a message.
- IP addresses are processed in transit but are not stored in our database.
- Payment card details and your Apple ID or Google account are handled by Apple and Google and are never sent to us.
We do not collect: your name, email address (unless you email us), phone number, date of birth, postal address, contacts, photos, camera or microphone, precise location, health data, or user-generated text or chat.
3. Advertising and collection by third parties
Ads are served by Google LLC and its affiliates ("Google") through AdMob. The ads SDK does not run until the first time you tap an ad button. It collects the following directly from your device, under Google's own privacy policy:
| Collected by Google | Purpose |
|---|---|
| Device identifiers (such as the advertising ID) | Serving ads, frequency capping, measurement, fraud prevention |
| Advertising data (ads viewed and tapped) and in-app interactions | Serving and measuring ads |
| Approximate location derived from IP address | Regionally relevant ads, fraud prevention |
| Diagnostics (crashes, performance) | SDK stability |
- iOS: the advertising identifier is used for personalised ads only if you allow it in the App Tracking Transparency prompt. If you decline, the Game and its ad rewards work the same and you see non-personalised ads. You can change this in Settings → Privacy & Security → Tracking.
- Android: you can reset or delete your advertising ID in Settings → Google → Ads.
- EEA, UK and Switzerland: a consent message appears before your first ad. You can reopen it at any time from Settings → "Ad privacy settings" in the Game.
- To verify ad rewards we pass Google your anonymous account ID and a one-time value, and Google notifies our server when the ad has been watched.
- How Google uses information: https://policies.google.com/technologies/partner-sites · Google Privacy Policy: https://policies.google.com/privacy
Apart from the above we do not share or sell your personal information, except where the law requires disclosure. In the terms of some US state laws, the use of advertising identifiers for personalised ads may be a "sale" or "sharing"; you can opt out with the controls above.
4. Service providers and international transfer
| Recipient | What they do | Information | Where |
|---|---|---|---|
| Cloudflare, Inc. | Hosting of the game server and database, network security | Everything in section 2 except emails | United States and other countries where Cloudflare operates data centres |
| Google LLC (Google Workspace email) | Receiving and storing support email | Emails you send us | United States |
MintC Inc. is based in the Republic of Korea. Your information is therefore processed outside your country, including in the United States and Korea, and is protected in transit by encryption (HTTPS).
5. Legal bases (EEA and UK)
- Performance of a contract — account, progress, gems ledger, purchases, ad rewards, leaderboard: needed to provide the Game you asked for.
- Legal obligation — purchase records kept for 5 years.
- Legitimate interests — usage events and fraud prevention, to keep the Game working and fair.
- Consent — personalised advertising, through the consent message and the App Tracking Transparency prompt. You can withdraw it at any time.
6. Deletion and retention
- When a retention period ends or you delete your account we erase the information so that it cannot be recovered.
- Deleting your account removes the link to your account ID, your progress, gems ledger, ad reward records, ranking records and display name, usage events and platform link. Purchase records are kept for the period in section 2 without a link to your account.
- Usage events are deleted automatically after 180 days.
- Information Google collected for advertising is held by Google; use the controls in section 3.
7. Your rights
Depending on where you live you may have the right to access, correct, delete, restrict or object to the processing of your information, to receive a copy of it, and to complain to your data protection authority.
- Delete: Settings → Account → Delete account in the Game, or https://courtstratagem.mintcinc.com/delete-account/
- Anything else: email support@mintcinc.com with the player number shown in Settings → Account. We do not hold your name or email address, so the player number is how we find your account. We answer within 30 days.
- We do not discriminate against you for exercising these rights.
8. Children
The Game is not directed to children under 13 (under 14 in Korea), and we do not knowingly collect personal information from them. If we learn that we have, we delete it. Parents and guardians can contact support@mintcinc.com.
9. Security
All traffic is encrypted (HTTPS). Access to server data is limited to the people who need it. Accounts are recognised only by tokens signed by our server, and an account can be moved to another device only with a proof signed by Apple or Google. Payments are made only through Apple's and Google's systems; we never receive payment details.
10. Cookies
The Game does not use web cookies. An identifier for your anonymous account and your settings are stored on your device and are removed when you uninstall the app. The website that hosts this policy uses no cookies or analytics.
