Welcome to Hanzi Puzzle (the “App,” “we,” or “us”), an offline puzzle game independently developed and operated around decomposing Chinese characters into strokes.
We value your privacy and handle information generated through the App in accordance with applicable privacy laws and the rules of the app store through which you obtained the App.
This Policy explains what information the App processes, why it is processed, which third-party services are used, your rights, and how information is protected. Please read it carefully before using the App. By downloading, installing, launching, or continuing to use the App, you acknowledge this Policy.
No account is required, and the App does not upload the following information to any server operated by us:
The following data remains only on your device or in the iCloud associated with your Apple ID and is not readable by us:
| Data | Purpose | Storage |
|---|---|---|
| Level progress, stars, and best times | Restore progress and display it on the level screen | Device Keychain; Application Support backup |
| Coin balance | Display and deduct coins for hints or skips | Device Keychain; synced between your devices through iCloud Key-Value Store |
| Music and sound preferences | Remember your settings | Device UserDefaults |
| Purchase status | Confirm coin-pack purchases and credit coins | Processed by Apple StoreKit; only the transaction result is temporarily returned to the App |
The current version does not request sensitive system permissions.
| Permission | Status | Reason |
|---|---|---|
| Precise or approximate location | Not requested | Not needed |
| Camera | Not requested | Not needed |
| Microphone | Not requested | Not needed |
| Photos | Not requested | Not needed |
| Contacts | Not requested | Not needed |
| Notifications | Not requested | Not needed |
| App Tracking Transparency / IDFA | Not requested | The App does not invoke IDFA tracking |
| Name | Provider | Purpose | Status |
|---|---|---|---|
| Apple StoreKit | Apple Inc. | Coin-pack in-app purchases | Enabled |
| Apple iCloud Key-Value Store | Apple Inc. | Sync coin balance through your Apple ID | Enabled |
| Apple Keychain | Apple Inc. | Secure local storage of balance and progress | Enabled |
| Google Mobile Ads SDK (AdMob) | Google LLC | Reserved for possible rewarded or interstitial ads in a future international release | Not enabled |
StoreKit, iCloud, and Keychain are iOS system services. Apple may process information associated with your Apple ID while providing them. Apple controls that processing, and the App developer cannot access it. See the Apple Privacy Policy.
AdMob is reserved in the App's dependency list but is not initialized or called in the current version, so it does not currently collect or transmit data. If enabled later, it may process IDFA only after ATT consent, device model, system version, approximate region, and ad interactions. We will update this Policy before enabling it. See the Google Privacy Policy and Google Mobile Ads SDK disclosure.
The data described in Section 2.2 is stored on your device or in your Apple ID's iCloud. We operate no user-data server. Device data remains until you delete the App, clear the relevant iCloud data, or erase your device. Some Keychain data may remain after uninstalling due to iOS behavior.
We do not actively share, sell, or transfer your personal information. Disclosure would occur only with your explicit consent, when required by law or binding governmental or judicial process, or when necessary to protect the lawful rights of the App, users, or the public.
No system is absolutely secure. If a personal-data incident occurs, we will comply with applicable notification and reporting requirements.
You can view your coin balance, level progress, and preferences inside the App. The App maintains no additional hidden user profile.
You may stop using the App and delete its data to withdraw consent. Withdrawal does not affect prior lawful processing. For privacy questions or complaints, contact us using Section 10.
The App is an all-ages puzzle game suitable for children. It does not collect information that identifies children and contains no social, chat, or user-generated-content features. Because it offers coin-pack purchases, parents should consider enabling iOS Screen Time → Content & Privacy Restrictions → Purchases. A guardian who identifies an unauthorized use or purchase may contact us for assistance.
We may update this Policy from time to time. The revised version will be posted in the same location with a new version and effective date. We will provide a prominent in-app notice for material changes, such as broader data collection, a new purpose, or a newly enabled third-party SDK.
For questions, feedback, or complaints about this Policy or the App's information practices, contact:
We will respond within 15 business days after receiving your request.
