This privacy policy applies to the Chinese Hanzi Puzzle mobile application (the "Application"), operated by 北京远景智业信息技术有限公司 ("we", "us", or the "Service Provider").
Chinese Hanzi Puzzle is designed to work primarily offline. We do not require an account, we do not collect personal information, and we do not use third-party analytics or advertising trackers.
The Application collects very little data. Specifically:
The Application does not embed any third-party analytics, advertising, or crash-reporting SDKs. The only third parties that may receive any data from your device are the platform billing systems you choose to interact with:
We do not sell, rent, lease, or otherwise commercially share any personal information. We do not share data with advertising networks, data brokers, or social-media platforms.
The Application is suitable for general audiences, including children. We do not knowingly collect personal information from children under 13 (or such higher age as required by applicable local law, such as under 14 under China's PIPL or under 16 under the EU GDPR). Because the Application does not collect personal information at all, no special handling is required. If you believe a child has provided us with personal information, please contact us so we can address it.
Because we do not maintain accounts or store personal data on our servers, there is no personal data for us to provide, correct, or delete. You can remove all locally stored data at any time by uninstalling the Application. Uninstallation also revokes any entitlements held through Google Play / Apple App Store (subject to the platform's own restore rules).
Depending on where you live (for example, the European Economic Area, the United Kingdom, California, or mainland China), you may have additional statutory rights with respect to personal information. Since we do not collect personal information, most of these rights are not applicable, but if you have a question, please contact us.
We use commercially reasonable safeguards to protect the limited data we do handle. Payment processing is delegated entirely to Google Play and Apple App Store, which use industry-standard encryption in transit and at rest. Because the Application does not transmit personal data to our servers, the attack surface is minimal.
We do not transfer your data internationally because we do not collect it on our servers. Any cross-border transfer of payment metadata is governed by the privacy policies of Google Play and Apple App Store, which operate the applicable data centers.
We may update this policy from time to time. When we do, we will revise the "Last updated" date at the top of this page. If the changes are material, we will make a reasonable effort to notify users through the Application. The most current version of this policy is always available at the URL provided on the Google Play listing for the Application.
