隐私政策Privacy Policy

This policy applies to MoonNote, provided by HanMiao Studio (“we,” “us,” or “our”). MoonNote is a personal period and health-tracking tool. It does not provide diagnosis, treatment, or professional medical advice. Cycle and ovulation estimates are for reference only and must not be used as the sole basis for contraception, conception, or medical decisions.

Depending on the features you use, MoonNote processes data you choose to enter, including period dates and flow, symptoms, mood, weight, basal body temperature, sexual activity records, ovulation test results, notes, fertility planning, pregnancy records, fetal movement, and prenatal checkup records.

If you choose cloud sync, we also process the email identifier and authentication credentials you provide. Email ownership is not verified, but the identifier is still protected as email information. Firebase and Supabase may process IP addresses, device information, and necessary service logs for authentication, security, abuse prevention, and service operation.

We do not sell personal or health data and do not use it for advertising.

We use data to provide cycle and health records, estimates and statistics, reminders, fertility and pregnancy features, data export, optional backup and restoration, multi-device sync, account security, and troubleshooting.

Without an account or sync, health records remain on your device. Removing the app or clearing app data may permanently erase local records.

When you voluntarily create an account and use sync, your account identifier and the health records selected for synchronization are transmitted over an encrypted connection for backup, restoration, and use across devices. Firebase provides authentication and sync services for users outside mainland China; Supabase provides those services for users in mainland China.

Google Firebase and Supabase act as service providers for authentication, cloud storage, and synchronization. Data may be processed in countries or regions where their infrastructure operates, subject to their applicable terms and privacy practices. We do not authorize them to use your health data for advertising.

Notification permission is used for period, ovulation, check-in, pregnancy, and prenatal reminders. Network access is used for authentication and optional cloud functions. You can disable notifications in system settings.

We use reasonable safeguards, including HTTPS/TLS in transit and restricted service access. Authentication credentials are handled by the relevant authentication provider; we do not intentionally store plaintext passwords in the health-record database.

Local data remains until you delete it, clear app data, or uninstall the app. Cloud data remains until you delete cloud records or delete your account. Residual copies in disaster-recovery backups may remain for a limited backup rotation period. MoonNote does not currently offer password recovery or reset, so losing your credentials may prevent account and synced-data recovery.

You can view, correct, export, and delete records in the app; clear local data; delete cloud records; and delete your account together with associated cloud data. See our Account and Data Deletion Guide, or contact hello@hanmiao.me.

MoonNote is not directed to children under 13, and we do not knowingly collect their personal data. We may update this policy as features, providers, or legal requirements change. Questions and privacy requests can be sent to hello@hanmiao.me.
