BlushDay Period Tracker

BlushDay is a private, local-first period and cycle tracker for adults. Record period dates, flow, pain, mood, energy, symptoms, medications and notes without creating an account.

Built for private everyday use:
- Your cycle and wellbeing entries stay on your device
- See cycle estimates, a clear calendar and useful summaries
- Set optional local reminders
- Protect the app with device authentication and hide content in Recents
- Export CSV files and delete all app data whenever you choose
- Use the interface in nine languages

BlushDay Pro is an optional one-time purchase, not a subscription. It removes the free-version banner and unlocks custom symptoms, detailed insights, password-encrypted backup and restore, doctor PDF reports and additional themes.

BlushDay is a wellbeing record, not medical advice, diagnosis, treatment, emergency support or contraception. Cycle estimates may be inaccurate. Contact a qualified healthcare professional about health concerns.
