Period Private
iOS Universel / Forme et santé
Period Private is the period tracker for people who don't want a tech company knowing their cycle.
There's no account to create. There's no cloud to sync to. There are no ads, no analytics SDKs, no third-party trackers, and no AI features that send your data anywhere. Every byte you log lives in a single encrypted database on your iPhone, protected by iOS Data Protection and — if you choose — by Face ID, Touch ID, or a PIN.
**Complete daily logging**
Mark period days with flow level, log up to 14 symptoms (cramps, headaches, bloating, fatigue, and more), capture nine mood states, jot free-form notes, optionally track basal body temperature, and record sexual activity if you want to.
**Smart on-device predictions**
Period Private learns from your last six cycles to estimate your next period, your ovulation day, and your fertile window. All math runs locally — no server round-trips, no "AI insights" pulled from a black box.
**A calendar built for cycles**
A clean month view shows period days, predicted periods, the fertile window, and ovulation at a glance. Tap any day to log or edit it.
**Insights that respect your time**
See your average cycle length, average period length, total cycles tracked, a history chart, and your most-frequent symptoms — without anyone analyzing you in the background.
**Privacy you can verify**
The app declares zero data collection in its Apple Privacy Manifest. App Transport Security is fully enabled, and the app makes no network requests. You can read the full privacy policy in the app or on our website.
**Your data, your call**
Export your full history as a JSON file you control, import it on a new device, or wipe everything instantly from Settings. There is no "deactivate account" page because there is no account.
Designed in the U.S. Built for everyone who wants a tracker that works on a plane, in a bunker, or just in peace.
