Frequently Asked Questions
Everything you need to know about tracking your cycle with CycleHub.
Is my data secure?
Yes. We built CycleHub with a strict privacy-first architecture. Your data is stored locally on your device using your browser's local storage. We do not have servers, databases, or accounts. Your information never leaves your device.
How do I track my period?
Navigate to the Tracker page and tap the date on the calendar when your period started. The app will automatically calculate your cycle length based on the distance between your logged dates.
How is my next period predicted?
We look at your past logged periods to determine your average cycle length (excluding extreme outliers). We then add this average to your most recent period's start date to predict when your next one will begin.
Can I use this for birth control?
No. CycleHub is designed for educational and tracking purposes only.
The fertile window estimations are based on standard calendar calculations, which are not reliable enough to prevent pregnancy. Please consult with a healthcare professional for reliable contraception methods.
