本隐私政策说明「格物实验」（以下简称“本应用”，应用包名 com.zhangfeiyang.gewu）如何处理用户与设备数据。本应用由独立开发者 zhangfeiyang 开发与维护。使用本应用即表示您接受本政策所述的做法。
本应用是一款完全离线的互动科学仿真实验室。我们不收集、不存储、不传输任何可识别您个人身份的信息。
具体而言，本应用不会：
为提供正常功能，本应用会在您的设备本地保存以下偏好设置（使用系统提供的本地存储，仅存储在本设备，不会上传）：
这些数据始终保留在您的设备上，您随时可在应用的「关于与设置」页面清除，或通过卸载本应用将其全部删除。卸载后这些数据将无法恢复。
本应用仅申请以下一项权限，且不涉及任何敏感数据访问：
本应用不申请相机、麦克风、位置、存储、通讯录、电话等敏感权限。
由于我们不收集任何个人数据，因此我们不会与任何第三方共享、出售或出租您的个人信息。本应用不存在任何第三方数据接收方。
本应用面向科学学习与教学场景，适合所有年龄段用户，包括儿童。由于本应用不收集任何个人信息，因此对 13 岁以下儿童的使用同样符合 COPPA 等儿童隐私保护要求。
应用内的「关于」页面可能包含指向 PhET 交互式仿真项目（phet.colorado.edu）的参考链接，仅用于说明教学理念的来源。点击该链接将通过您设备上的浏览器打开外部网站，届时适用目标网站自身的隐私政策，本应用不再对外部网站的数据处理行为负责。
由于本应用不在设备之外处理或传输任何用户数据，因此不存在数据在传输或服务器存储过程中的泄露风险。本地存储的数据受您设备自身的安全机制保护。

This Privacy Policy explains how "Gewu Lab" (the "App", package name com.zhangfeiyang.gewu) handles user and device data. The App is developed and maintained by the independent developer zhangfeiyang. By using the App, you accept the practices described in this policy.
This App is a fully offline interactive science simulation laboratory. We do not collect, store, or transmit any information that could personally identify you.
Specifically, the App does NOT:
To provide its normal functionality, the App stores the following preferences locally on your device (using the local storage provided by the system, kept only on this device and never uploaded):
This data always remains on your device. You may clear it at any time from the "About & Settings" page within the App, or remove it entirely by uninstalling the App. After uninstallation, this data cannot be recovered.
The App requests only the following permission, which does not involve any sensitive data access:
The App does not request camera, microphone, location, storage, contacts, phone, or other sensitive permissions.
Because we do not collect any personal data, we do not share, sell, or rent your personal information with any third party. The App has no third-party data recipients.
The App is intended for science learning and teaching scenarios and is suitable for users of all ages, including children. Since the App collects no personal information, its use by children under 13 also complies with children's privacy requirements such as COPPA.
The "About" page within the App may contain a reference link to the PhET Interactive Simulations project (phet.colorado.edu), included only to acknowledge the source of the teaching philosophy. Clicking this link opens the external site in your device's browser, at which point the target website's own privacy policy applies; the App is not responsible for the data practices of external websites.
Because the App does not process or transmit any user data outside the device, there is no risk of data leakage during transmission or server storage. Locally stored data is protected by your device's own security mechanisms.
We may update this Privacy Policy from time to time. Updated policies will be posted on this page, with the "Last updated" date at the top reflecting the change. We recommend you review this page periodically for any updates.
If you have any questions about this Privacy Policy, you may contact the developer via GitHub: github.com/zhangfeiyang.
