Cycle: Private Period Tracker

iOS Universel / Forme et santé

Cycle is a period tracker that takes privacy as a hard rule, not a marketing line.

Other period apps store your cycle data on their servers. After Roe v Wade was overturned in 2022, that data became a real risk in some places. Cycle is built so that risk cannot exist: your data physically cannot leave your phone unless you turn on iCloud sync.

THE SIX TRUST PROMISES

1. Your data never leaves your phone unless you turn on iCloud sync.
2. No account. No email. No sign up.
3. No analytics. No telemetry. No third party SDKs.
4. Apple is the only company that ever touches your data, and only if you turn on iCloud.
5. Wipe everything in one tap, anytime.
6. Export everything in one tap, anytime.

If a feature breaks any of these promises, the feature loses.

• iCloud sync between your own Apple devices
• Export everything as CSV, JSON, or a one-page PDF for your doctor

PRIVACY YOU CAN VERIFY

App Store privacy nutrition label: Data Not Collected. That is the strongest privacy claim Apple lets a developer make.

No Firebase. No Mixpanel. No Sentry. No AppsFlyer. No ad SDKs. Only Apple frameworks ship in the binary. We list every framework in our privacy policy, in plain language a 14-year-old can read.

DESIGNED FOR ONE-HANDED USE

The calendar is the home screen. The "log period" button is reachable by your thumb. No feed. No social features. No paywall pop-ups while you log. No condescending copy ("Yay, your period is here").

If you cancel a subscription, premium features stay until the end of your billing period, then drop to free. Your data stays untouched.

FOR ANYONE WHO TRACKS A CYCLE

Cycle is built for women, trans men, non-binary people, and anyone who tracks a cycle without wanting an app that assumes you are trying to conceive.
