FAQ
Questions about Niyora and Apple Health
Which period trackers work with Apple Health?
Apple’s own Cycle Tracking keeps your periods in the Health app. Clue and Natural Cycles write periods to Health once you turn on their sync. Flo and Bearable don’t write periods to Health. Niyora reads period days from Health and uses them for your calendar and your PMS window.
Does Niyora write to Apple Health?
Niyora never writes to Apple Health. It only reads your period days, so your Health data stays as you left it. You can turn off Niyora’s access at any time in the Health app: tap your picture, then Apps under Privacy, then Niyora.
How far back does Niyora read my Apple Health history?
All of it. The first time you connect, Niyora reads your whole period history in Apple Health, so your past cycles are there from day one. After that, it reads what is new each time you open it.
Does Niyora read my symptoms and moods from Apple Health?
No. Niyora reads only your period days from Health, not the symptoms you log in Cycle Tracking or your moods. Your period days stay on your phone. The one thing sent is a yes or no on whether today is one of the days before your period, with what you ask Moon.
Can I keep logging my period in Apple Health?
Yes. Keep logging your period in Apple Health, or in a tracker that writes to Health. Each time you open Niyora, it reads the periods that are new in Health and updates its calendar and your PMS window. You can also log a period in Niyora itself.
