CycleSync

CycleSync projects your menstrual cycle across four phases — Menstrual, Follicular, Ovulatory, Luteal — about a year ahead as all-day events in a dedicated 🌸 Cycle Tracker calendar in your own Google account. Pick a new start date whenever your period arrives and it recalculates the year.

CycleSync only uses Google Calendar access to create and manage its own cycle-phase events. It never reads your other calendars, and it stores no data on any server.
