Optional support

If Lunarosa is useful to you, you can chip in from inside the app. It helps keep the project running — there is no pressure, and nothing is taken away if you don't. Supporting the app does not change the encryption: your data stays unreadable to us either way.

Why is it free?

Because the usual way to make a period app free is to sell what it learns about you. Lunarosa can't do that — your data is encrypted with a key it doesn't have. So there are no ads, no investors, and no data sales. The app is kept running by the people who find it useful.
