Privacy Policy for MoonVite (邀月)

Effective Date: September 27, 2026 | Last Updated: September 27, 2026

This Privacy Policy applies to MoonVite (邀月), published on Google Play under the Developer Name: 朕乃万岁-道法自然，顺其自然 and developed by Zhang Huiwu (张辉武).

We respect your privacy. MoonVite is designed as a standalone/offline application for recording and managing menstrual cycles and related personal information. During normal use, information entered into the app is stored locally on your device and is not uploaded to a developer-operated server. The app does not require a user account or login to a developer server.

1. Developer and Privacy Contact

App Name: MoonVite (邀月)

Google Play Developer Name: 朕乃万岁

Developer/Author: Zhang Huiwu (张辉武)

Privacy Contact Email: 280880560@qq.com

For questions about this Privacy Policy, privacy practices, or personal data handling, please contact the developer using the email address above.

2. Data We Handle

MoonVite is designed to operate locally on your device. Based on the current version, the app does not actively upload the following information to the developer:

• Menstrual start dates, end dates, and cycle records;
• Period or ovulation information recorded or calculated locally by the app;
• Notes, weight, body-management records, where such features are available;
• Desire/libido or cycle-related records, where such features are available;
• Local profiles created for yourself, your daughter, or another person;
• Statistics, predictions, or results generated from the above local information.

3. Data Sharing and Third Parties

The core functionality of MoonVite is offline. Based on the current version, your personal records are not uploaded to a developer-operated server and are not sold or shared with third parties for advertising, analytics, marketing, or other commercial purposes.

The app does not require users to register an account or log in to a developer server.

Third-party SDKs: This Privacy Policy is based on the current version not including any third-party SDK that collects, uploads, or shares users' personal or health-related data. If a future version adds advertising, analytics, crash reporting, cloud synchronization, or another third-party service, this Privacy Policy and the Google Play Data Safety disclosure will be updated accordingly.

4. Data Storage

Information that you enter into the app is primarily stored locally on your device and is used to provide cycle tracking, statistics, and related features. The developer cannot directly view these locally stored records through the app.

If you use Android's system backup, restore, or device-transfer features, whether and how app data is backed up may depend on Android, your device manufacturer, and your system settings. Such system-level backup is not an upload initiated by the developer.

5. Data Retention and Deletion

Because the app does not create user accounts or store user records on developer-operated servers, the developer does not retain user records on its servers.

You may delete local records using any deletion function provided by the current version of the app. If the current version does not provide a separate deletion function, you may clear the app's data through Android system settings or uninstall the app. Clearing app data or uninstalling the app may delete records stored locally on the device.

If a future version introduces accounts, cloud synchronization, or server-side storage, this Privacy Policy will be updated and an appropriate deletion mechanism will be provided.

6. Data Security

We use safeguards appropriate to the app's offline design to protect locally stored data. Because data is primarily stored on your device, your device passcode, system security settings, backup settings, and device-management practices also affect data security. We recommend using a secure device lock and protecting access to your device.

7. Permissions

The app requests Android permissions only when they are necessary for a particular feature. If a future version requests access to photos, notifications, calendars, health data, device storage, or other system resources, the relevant purpose will be explained and the feature will be handled in accordance with applicable Android and Google Play policies.

8. Health and Medical Disclaimer

MoonVite is a menstrual tracking and cycle management tool. Cycle calculations, predictions, statistics, and other information provided by the app are for personal tracking and general informational purposes only and do not constitute medical diagnosis, treatment, or professional medical advice.

If you have a medical concern, unusual bleeding, severe pain, significant menstrual irregularities, or any condition requiring medical judgment, please consult a qualified healthcare professional.

9. Children's Privacy

The app is not specifically designed as a child-directed service. We do not intentionally create child user accounts or collect children's personal information through the app. If you create a local record for your daughter or another family member, that record is handled as local data on the device in accordance with this Privacy Policy.

10. Changes to This Privacy Policy

We may update this Privacy Policy when the app's features, data practices, applicable laws, or platform policies change. The updated policy will be published on this page, together with an updated "Last Updated" date.
