Cyclus

Privacy Policy

Last updated: September 14, 2026

Cyclus is a cycle tracking app designed to work fully offline on your device. Your intimate health data stays under your control.

Data stored on your device

Cyclus may store locally: profile name and local password, cycle dates and logs, symptoms and notes, tracking mode, theme preferences and background photo, notification settings, and optional partner PIN / export files you create. This data is stored on-device and is not uploaded to Cyclus servers.

What we do not collect

Permissions

Cyclus may request notifications and exact alarms for reminders you enable; photo/file access only when you pick a background or import/export a share file; and vibrate / wake / boot permissions to support local reminders.

Sharing

Optional partner sharing is initiated by you (PIN or exported file). Anything you send through another app is governed by that app’s policies.

Children

Cyclus is not directed at children under 13 (or the minimum age in your country).

Medical disclaimer

Cyclus is not a medical device. Predictions are estimates only. Seek professional care for medical advice.

Deletion

Clear app storage or uninstall Cyclus to remove local data on that device.
