Log period start and end dates, flow, mood, symptoms, notes, sex, contraception, and basal body temperature. Review your cycle history and patterns over time. Your data stays on your Apple device unless you choose private iCloud sync. Cycle does not predict future periods, ovulation, fertile windows, pregnancy, or medical conditions. It is a private diary of the information you record.
