What you can be reminded about
The four reminder types are independent, so you can keep only the ones you want. They share one delivery time chosen in Settings.
Expected period, fertile-window start, and estimated ovulation support 0–3 days of lead time. Fertile-window end is currently delivered on the estimated end date. Turning a reminder off does not remove the corresponding calendar highlight.
Setting reminders up for the first time
Open Settings inside MiniCycle and find Notifications. The first time you enable a reminder, iOS asks for permission. Without system permission, MiniCycle cannot display the scheduled alerts.
Choose the lead time for the supported reminder types and select a delivery time you are likely to notice. The current fertile-window end scheduler uses the estimated end date itself; changing its visible lead option does not change the scheduled date in this app version.
Choosing a lead time
A reminder on the estimated date is a same-day prompt. One day earlier leaves time to prepare, while two or three days can be useful when planning around travel or work. There is no medically correct lead time because every reminder is based on an estimate.
If you only want advance notice of the next expected period, enable just that reminder. More alerts do not make the underlying prediction more accurate.
Where the dates come from
Reminders are scheduled from MiniCycle's current calendar estimates. Recording a new period start or changing a relevant setting recalculates the dates and rebuilds the pending local notifications.
They are planning prompts, not measurements of menstruation or ovulation. If the actual event differs from the reminder, record what happened so later estimates can use the updated date.
Reminders are scheduled on your phone
MiniCycle reminders are local notifications. Apple's notification framework lets an app generate notifications locally on the device instead of pushing them from a server, and that is the mechanism MiniCycle uses. There is no MiniCycle account, and your reminder schedule is not uploaded to a MiniCycle server.
This matches how the rest of the app handles data. Period records stay on the device by default, and turning reminders on does not change that.
If a reminder does not arrive
Check three things in order. First, that the reminder is enabled inside MiniCycle and the app has notification permission in iOS Settings. Second, that a Focus mode or scheduled notification summary is not holding the alert back. Third, that there is a predicted date for the reminder to attach to. With no saved period records, there is nothing to schedule.
Apple's support page on iPhone notifications covers the system-side settings, including alert styles, Focus, and per-app notification options.
