PERIOD. Cycle & Period Tracker

About

Your cycle, your data. No selling, no hidden trackers, no ads. Remember when women were told to delete their cycle app in 2022? That happened because some apps in this category shared user data despite promising not to. The biggest one settled with the US regulator over sharing cycle data with a large social media platform. We thought that was a mediocre outcome. So we built PERIOD. WHAT IS INSIDE Period and cycle tracking. Ovulation and fertile day predictions. Symptom logging for energy, sleep, skin, libido, pain, mood, and more. Basal temperature and ovulation test tracking. A home screen widget with your cycle at a glance. Explanations for each phase of your cycle. AI questions that know what is in your data. Calmly designed, without dark patterns. PERIOD. baby, FOR THE WHOLE JOURNEY Life does not stop at cycle tracking. PERIOD. baby is one subscription that grows with you across four life stages: your cycle, trying to conceive, pregnancy, and the time after birth. The app quietly changes to match where you are. Trying to conceive: your fertile window, ovulation tests you can compare side by side on your own photos, and a place to log a pregnancy test. Pregnant: your pregnancy week by week with a calm ring, what is happening each week, appointment reminders, a hospital bag checklist, a kick counter, and a contraction timer when the time comes. After birth: a gentle recovery view, week by week, that never rushes you. And if a pregnancy ends, the app meets you with care, and moving back to your cycle is always free. No medical claims, no diagnosis. Just a calm companion that knows where you are. PRIVACY IS THE FOUNDATION Your cycle and health data live on servers in the EU. Always encrypted. No tracking pixels, no advertising networks, no ad identifiers. You can export or delete everything whenever you want. Our AI never trains on your data. The full list of companies that ever touch any of your data is on myperiod.app/sub-processors. We earn from subscriptions, not from your data. FOR YOURSELF AND FOR WORK The basic features stay free.
