Our mission
Period Tracker was built with a single goal: give everyone a free, accurate, and genuinely private way to understand their menstrual cycle. No account. No cloud. No data harvesting.
We believe that health data — especially reproductive health data — belongs to the person it describes. That's why your cycle information never leaves your device. Everything is stored in your browser's localStorage, which is private, local, and under your control.
What we offer
Our suite of free, no-login tools includes:
- Period Tracker — a full-featured cycle calendar with history, flow tracking, and PDF export
- Ovulation Calculator — predict your fertile window and ovulation date
- Due Date Calculator — calculate your estimated delivery date from your last period
- Implantation Calculator — estimate implantation dates after ovulation
- Period Calculator — predict your next several periods
We also publish a growing library of menstrual health guides written in plain language, with citations to reputable medical sources.
Privacy by design
Unlike most period apps, we do not require an account, do not sync to the cloud, and do not sell or share your health data. All data you enter stays in your browser's localStorage. We have no access to it.
The site does display third-party display advertisements to cover hosting costs. These ad networks may use cookies for ad personalisation, as described in our Privacy Policy. Your cycle data is entirely separate from any advertising systems.
Medical disclaimer
All tools on this site are for informational and educational purposes only. They are not medical devices and do not provide medical advice. For health concerns related to your menstrual cycle, please consult a qualified healthcare professional. See our full medical disclaimer for more information.
