Track your cycle with total privacy. Period tracker, ovulation calendar, mood logger & PMS reminders. No account, no sharing, 100% on-device.
Period : Cycle Tracker
The period tracker that never leaves your phone.
Your body is yours. So is your data.
Period : Cycle Tracker is a beautiful, intuitive period tracker built around one radical idea: your most personal information belongs to you — not to advertisers, not to data brokers, not to us. Track your cycle, understand your patterns, and learn your body's language. Completely privately.
YOUR DATA STAYS ON YOUR DEVICE. FULL STOP.
No Account, Ever: Start tracking the moment you download. No email, no sign-up, no footprint.
On-Device Only: Everything you log lives on your phone — never uploaded, never stored on our servers.
Zero Data Selling: Not now, not ever, not under any circumstances. That's not our business model.
UNDERSTAND YOUR BODY, CYCLE BY CYCLE
Periods & Forecasting: Log your flow and let Your Rhythm predict what's coming — weeks in advance.
Fertile Window & Ovulation: Know your most fertile days, whether you're planning for or avoiding pregnancy.
Symptoms & Moods: Connect the dots between your cycle phase and how you actually feel — energy, cramps, headaches, mood shifts, and more.
Irregular Cycles: Fully flexible tracking that adapts to your unique rhythm, not the other way around.
Intimate Life: Optionally log sexual activity to understand how desire and energy shift through your cycle.
QUIETLY SMART, NEVER INTRUSIVE
Gentle reminders for your period, PMS window, ovulation, and fertile days — only when you want them.
FOR EVERY BODY, AT EVERY STAGE
Just Starting Out: Build body awareness from day one. No experience needed, no judgment.
Irregular Cycles: Your pattern is valid. Your Rhythm works with it, not against it.
Family Planning: Use accurate ovulation predictions to plan — or prevent — on your own terms.
