The difference
What you get with Kalena.
Most period apps are built around extracting value from you. Kalena isn't.
A period and fertility tracker that works fully offline. No account. No data sharing.
Get it on Google PlayAll your data saved locally on your device. We have no servers or databases.
Free to use core features. One-time premium unlock for further insights and BBT tracking.
Is your cycle 21 days, 45 days, or doesn't follow a textbook pattern at all? Kalena adapts to you.
Features
A clean, considered interface designed to fade into the background — so you can log a day in seconds and get on with yours.

The difference
Most period apps are built around extracting value from you. Kalena isn't.
Privacy by design
Most period apps say they protect your privacy. We're built differently — we physically cannot see your data because it never reaches us.
