How do I log a period day?
Open the Calendar tab, tap on the date, and choose "Log Period." You can also add notes about your physical condition and activity for that day.
Can I edit multiple days at once?
Yes — in the Calendar tab, tap the edit icon to enter Editing Mode, then tap each date you want to mark or unmark, and hit Save.
How is my cycle length calculated?
You can set your average cycle and period length manually in Settings. Moonarie uses these values to predict your next period and fertile window.
Is my data private?
Yes. Your cycle data stays on your device and is never sold or shared. See our Privacy Policy for full details.
How do I turn on reminders?
Go to Settings → Notifications, and enable Period, Delay, or Ovulation reminders individually. Nothing is turned on by default.
