Offline-first menstrual cycle tracker with local-only data

Cycle Whisper is an offline-first menstrual cycle tracker for Android designed around local-first storage. Cycle data is sensitive, and many users want a calm tracker without accounts, cloud sync, or complicated onboarding. Cycle Whisper keeps the flow simple: log period days, optionally add symptoms and notes, and review your calendar and history.

The app is built to work without a developer-controlled backend for cycle content. Your entries are stored on your device and remain under your control. When you need to move data, you can export or back up your information using user-initiated tools. Some versions may provide optional protections like app lock or encryption features to reduce casual access on a shared device.

If you’re looking for a privacy-first period tracker that stays lightweight and offline-first, Cycle Whisper is built for that goal. Read the Privacy Policy for details about optional features such as ads or purchases that may be enabled in some configurations.
