Havi privacy policy

Last updated: 28 October 2026

Havi is a period tracker that keeps everything on your phone.

What Havi collects

Nothing. Havi has no account, no server, no analytics, no advertising and no third-party tracking. The developer never receives any of your data.

What Havi stores on your device

The days, flow, symptoms, moods and notes you log, and your settings (reminder and lock preferences). This data is stored only in the app’s local storage on your device.

• Device backups. Your phone’s own backup (iCloud or Google) may include the app’s data, under that service’s terms. Havi does not control this.
• Backup files. If you choose “Back up to file”, Havi creates a file and opens the system share sheet. Where that file goes is up to you.
• Reminders. If you turn on the reminder, Havi schedules a notification on your device. Nothing is sent to a server.
• App lock. If you turn on the lock, your device’s Face ID, fingerprint or passcode check is used. Havi never sees or stores your biometric data.

Deleting your data

Use Settings → Delete all data in the app, or uninstall the app. Either removes everything Havi has stored on the device.

Children

Havi is not directed at children under 13 and collects no data from anyone.

Medical disclaimer

Havi is not a medical device and does not replace medical advice. Predictions are based on averages and can be inaccurate. It must not be used as contraception or to prevent pregnancy.

Changes

If this policy changes, the new version will be published at this address with a new date.
