Questions

Is Lunalia free?

Yes. Lunalia is free to download and use.

Where is my data stored?

Only on your iPhone. Lunalia has no servers and no account, so your data is never sent anywhere.

How accurate are the predictions?

Lunalia learns from your last six cycles. The more you log, the more accurate it gets. Predictions are estimates, not medical advice.

Can I use Lunalia as contraception?

No. Lunalia is not a medical device and must not be used as a method of contraception.
