PERIOD. — the honest cycle app from the Netherlands. Privacy is not a feature. It is the foundation. We do not sell your data. We do not share it with advertisers, "partners" or third parties. No trackers. No advertising. No data brokers. Your cycle, your data — never for sale. We just help you understand your body. WHAT YOU GET • Period tracker and cycle calendar with reminders • Ovulation and fertile day predictions that learn from your cycle • Symptom logging — energy, mood, sleep, skin, libido, pain, cramps and more • PMS, PCOS, endometriosis and irregular cycles: see your patterns and share them with your doctor • Doctor report: export your cycle history as a PDF • Cycle phase explanations: follicular, ovulation, luteal, menstrual • AI questions about your cycle, personalised to you • Trying to conceive: BBT chart and fertile window (PERIOD. baby) • Pregnancy week by week and postpartum tracking (PERIOD. baby) • Calm, considered design — no dark patterns WHY WE ARE DIFFERENT Most cycle apps are built by men, for women, with your data as the business model. Cycle trackers have been at the centre of multiple privacy scandals — most notably the 2021 FTC settlement where one large app shared your data with Facebook. We built PERIOD. because we wanted something different. We are a small, Dutch, women-led team. Founder Lisa uses the app herself every day. Every design choice starts with: would I want this for myself? PRIVACY, BY DESIGN • Cycle and health data on EU servers (Frankfurt), encrypted in transit and at rest • No tracking pixels, no behavioural ads, no third-party SDKs • Export or delete everything, at any time • GDPR-compliant from day one • Full sub-processors list at myperiod.app/verwerkers Basic features stay free. We are a young app — not everything is done yet. But we build in the open, listen to the women who use it, and try to be the cycle app you would recommend to your friend. If that sounds like what you were waiting for — welcome. — Lisa & the PERIOD. team Amsterdam myperiod.app IMPORTANT PERIOD. is not a medical device and does not replace medical advice. Predictions are estimates. Always consult a doctor, midwife or other healthcare professional for medical advice, diagnosis or treatment, and do not use PERIOD. as a method of contraception.
