PLAIN LANGUAGE

Privacy at a glance

Four plain-language commitments that describe the current app and this website.

No account required We do not ask you to create a Tsumo Dragon account.
No ads or tracking The app and website do not use advertising SDKs or behavioral analytics.
Game data stays local Progress, settings, records, and achievements are stored on your device.
Apple handles purchases Full Game purchases are processed and verified through Apple StoreKit.

1. Data we handle

Tsumo Dragon does not operate an account system or game server. The app does not collect your name, email address, contacts, precise location, photos, health data, or advertising identifier. It does not include third-party advertising or analytics SDKs.

2. Data stored on your device

The app stores the information needed to provide its features locally on your iPhone. This includes settings, language choice, audio preferences, active-game save data, game summaries, records, achievements, yaku collection progress, and the free-game trial ledger. The trial ledger uses Apple Keychain to reduce accidental resets and duplicate counting.

Deleting the app or erasing the device may remove local game data. A non-consumable purchase can be restored with the Apple ID that originally purchased it.

3. In-app purchases

The optional Full Game purchase is processed by Apple using StoreKit. We receive verified entitlement status and transaction information required to unlock the purchase, but we do not receive or store your payment card number. Apple handles payment details under Apple’s privacy policy and App Store terms.

4. This website

This support website is hosted on GitHub Pages. It does not use advertising, analytics, tracking pixels, or cookies. If you choose a language, your browser may store that preference locally. GitHub may process basic server logs as the hosting provider under GitHub’s own privacy statement.

5. Children’s privacy

Tsumo Dragon does not knowingly collect personal information from children. Because the app has no account, chat, advertising, or user-generated content, it does not request age or profile information.

6. Your choices

You can change music, sound, haptics, language, and difficulty in Settings. You can remove locally stored app data by deleting the app. Purchase history and payment data are controlled through your Apple ID and Apple’s account tools.

7. Changes to this policy

If the app’s data practices change, this page will be updated before or when the relevant app version is released. The effective date at the top will show the latest revision.

8. Contact

For privacy questions or requests, contact us by email. Do not send payment card details, Apple ID passwords, or other sensitive credentials.
