Auralune

A private period and cycle tracker for iPhone. Your data lives on your phone — and stays there.

Zero data sharing, ever. We have no server, no analytics, no advertising SDKs. We could not hand your data to anyone because we do not have it.

What's inside

Period start/end with flow, 30+ symptoms, BBT, cervical mucus, LH tests.
Predictions learn from your last six cycles and weight recent ones higher.
Apple Watch quick log, Lock-Screen widget, optional Interactive widget (iOS 17+).
App Lock with PIN + Face ID. Optional Duress PIN that opens a decoy calendar.
One-tap "Burn all data" — overwrites the local store, deletes your iCloud zone, removes every key from the Keychain.
Optional end-to-end-encrypted iCloud sync. Off by default. Apple sees ciphertext only.

Subscription

Pro — $2.99/mo or $19.99/yr (7-day trial). Pro+ — $4.99/mo or $34.99/yr (14-day trial). Free tier includes period logging, 1-month history, basic predictions and App Lock.

Not a medical device

Auralune is not a medical device and not a contraceptive. Predictions are estimates derived from your own entries. If you are concerned about your cycle, see a clinician.
