ZiStep 字步 is a Chinese character writing practice app. The current version is designed to work without an account or a backend service.
In the current version, we do not collect, sell, rent, or share personal information with our servers. The app does not include an account system, advertising SDK, analytics SDK, or cross-app tracking.
Character lists, practice progress, settings, and other app content are stored locally on your device so that you can continue practice later. This information is not uploaded to us by the current version.
ZiStep offers optional in-app purchases handled entirely by Apple's App Store. Payment details are processed by Apple and are never sent to or seen by us. We receive only the entitlement status needed to unlock paid features on your device.
When you use pronunciation support, the app invokes the operating system's speech service. The app does not record or store your voice. Any processing performed by the operating system or its provider is subject to that provider's terms and privacy policy.
When you print or share a worksheet, iOS presents the system print or share sheet. The selected content is sent to the printer or app you choose. ZiStep does not control or receive content from the destination service.
The app reads the device language and locale to select the appropriate interface language. These settings are used locally and are not sent to our servers in the current version.
The app is intended for family learning and Chinese language practice. We do not knowingly collect personal information from children. Parents or guardians should supervise use of third-party print, share, and speech services.
The app includes Chinese character data from third-party open resources. Their license notices are included with the app. The app does not send practice content to those providers.
We may update this policy when the app's data practices change. Questions can be sent to zqqj2004@126.com.
