Cycle tracking that just works. No selling your data, no hidden trackers. The basics stay free. Built in Amsterdam, in 19 languages. 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 the big apps in this category have been trading user data for years. The biggest one settled with the US regulator for 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. Explanations for each phase of your cycle. AI questions that know what is in your data. Pregnancy and fertility tracking. Calmly designed, without dark patterns. PRIVACY IS THE FOUNDATION Your cycle and health data live on servers in the EU. Always encrypted. No tracking pixels, no advertising networks, no analytics from other companies. 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. Always. PERIOD. plus adds unlimited AI questions, deeper insights, and an exportable report for your doctor. 3,49 euro per month or 34,99 euro per year, with 14 days free to try. For employers there is PERIOD. at work. Your company gets activation codes for your team, employees activate anonymously, and you as the employer never see personal data. Info at myperiod.app/period-at-work. Available in 19 languages on iOS and Android. Live since March 2026, from Amsterdam. Questions or feedback? Email hi@myperiod.app. We read everything.
