My Luna
A calm way to follow your cycle — mapped to the phases of the moon.
Beta
Not on the App Store or Google Play yet. iOS testing runs through Apple's TestFlight app; Android opens later.
It stays on your phone
- No account needed. Open the app and start — there is nothing to sign up for.
- Nothing leaves the device on its own. Periods, symptoms, notes and intimacy logs are written to a database on your phone. Two switches can send some of it further — cross-device sync and sharing with a supporter — and both are off until you turn them on.
- Intimacy logs never leave. Not through sync, not through sharing, under any setting.
- No analytics, no crash reports, no ad identifiers. Not reduced tracking — none.
- Export or erase everything — on the phone and on the server — in a couple of taps.
The privacy policy spells out exactly what each switch sends, and what we can see.
What it does
The cycle ring
One dot per day of your cycle, so where you are today is a glance rather than a calculation.
Log what matters
Flow, symptoms, mood, notes — and your own custom fields for anything Luna didn't think of.
Forecasts from your own history
Your next period is estimated from the cycles you have actually logged, not a fixed 28 days.
Phases, explained
Each phase gets a moon, a colour and a plain-language guide to what is typical during it.
Gentle reminders
A nudge before a period is due, or to log the day. Scheduled on your phone, never on a server.
Share with a supporter
Invite a partner or friend into a read-only view of exactly what you pick — and disconnect any time.
My Luna is not a medical device and not a contraceptive. It describes patterns in what you log; it does not diagnose anything, and it is not a substitute for advice from a clinician.
