JustPeriod.

Track your cycle — or each other's. Two cycles side by side, end-to-end encrypted partner sharing, and zero ads. Your data never leaves your hands.

Just Period. is a period tracker built around two ideas most apps ignore: your cycle is private, and the people who care about you can be part of it — on your terms.

SHARE YOUR CYCLE, OR FOLLOW THEIRS • Pair with your partner using a one-time code — no accounts, no sign-ups • Both partners can track their own cycles side by side — built for every kind of couple, including two people who both menstruate • Your partner sees exactly what you choose: period days, symptoms, predictions, cycle phase — each one is a separate switch • Send a small sign of support with one tap, and tell your partner what you'd love right now on period days — with your own custom options • Stop sharing any time; your data disappears from their phone

MADE FOR REAL BODIES • Tracking modes for PCOS, endometriosis, fibroids, and PMDD • Contraception-aware predictions (pill, IUD, implant, and more) • Irregular-cycle support that doesn't pretend your cycle is a clock • No pregnancy assumptions, no fertility pressure — unless you turn fertility tracking on, it stays out of your way

PRIVATE BY ARCHITECTURE, NOT BY PROMISE • Everything is stored on your device, protected by iOS file encryption • Optional sync and partner sharing are end-to-end encrypted — we could not read your data even if we wanted to • No account. No ads. No analytics SDKs. Your data is never sold • App lock with Face ID / Touch ID / PIN, and a privacy screen in the app switcher • Password-protected exports (PDF / CSV / JSON) and encrypted backups • Import your history from Flo, Clue, or WomanLog in minutes

AND THE ESSENTIALS, DONE PROPERLY • Calendar, predictions, and cycle statistics that respect your settings • 20+ symptoms plus your own custom ones • Home screen and lock screen widgets, Apple Watch app • Optional Apple Health connection (heart rate, HRV, temperature, sleep) • Reminders that speak plainly and never spill secrets in notifications

FAIR PRICING The core app is free — tracking, calendar, statistics, import, export, backups, and reminders, forever. Partner sharing and visual customization are unlocked with a single lifetime purchase. No subscriptions, no recurring charges. Want to try partner sharing first? A promo code gives you 30 days of full access for free.

Just Period. Know your body. On your terms.
