No account. No cloud. No exceptions. Cycle prediction, symptom logging and HealthKit — all on your device.
A rotating visual calendar shows period days, fertile window, and luteal phase at a glance.
Forecasts show a ±2 day range — not a false single date. Accuracy improves as you log.
Enter your last period date. Luna Local starts predicting immediately — no questionnaire.
No account, no cloud sync unless you opt in. Logs live in your device's encrypted storage.
Switch to a neutral icon and generic notification text. Nothing reveals the app's purpose.
Optionally sync cycle data to Apple Health. Permission required; revocable any time.
App Store Privacy Label
Luna Local does not collect, transmit, or share any data. Your cycle logs stay on your device — or in your private, end-to-end encrypted iCloud account if you choose. We never see them.
Questions or feedback? Email dark2torch@gmail.com — usually replied to within a day or two.
Yes. Luna Local has no backend server. Your data lives in Apple's on-device CoreData database. If you enable iCloud sync, it travels through your own private iCloud account (Apple's CloudKit with end-to-end encryption). We never receive a copy. See our Privacy Policy for full technical detail.
Yes, completely. Luna Local is fully functional with no network connection. All computation runs on-device.
No. Luna Local provides general cycle awareness estimates only. It is not a contraceptive tool and should not be used as one. Consult a healthcare provider for contraception guidance.
Yes. Discreet mode only changes the home screen icon and notification text. All your logs and settings are untouched.
