Add your period to Google Calendar

Why put your period in your calendar at all?

Because your calendar is where decisions get made. When your period and phases are visible next to your meetings, you notice the clash before you accept the invitation — the launch that lands on day 1, the big presentation that could sit in your higher-energy follicular stretch instead. And your period is only a quarter of the story: Nadi maps all four phases — menstrual, follicular, ovulatory and luteal — so the whole cycle becomes something you can plan with, not around.

How it works

1. Go to my.nadi.health and answer three questions: your last period start date, your average cycle length, and your average period length.
2. Connect Google Calendar. Nadi creates a separate, dedicated calendar in your account and writes your phase events into it.
3. Plan as usual. Your phases sit alongside your events, updating as your cycle moves. Change your inputs whenever your cycle changes.

There is no app to download and no daily logging to maintain.

Your other events stay private

Nadi asks Google for the narrowest permission available (calendar.app.created). That means Nadi can only see and edit the one calendar it creates for you — it cannot read, access or change any of your other calendars or events. Disconnect at any time and you can remove the Nadi calendar directly in Google too. The full detail is in our privacy policy.

Honest by design

Your phases are estimates, calculated from the averages you provide — we publish exactly how. Nadi is a planning tool, not an ovulation predictor or contraceptive method.
