PeriodPrivate is a period and cycle tracker built on one premise: this data should never leave your phone. There is no account to create, no server to sync to, and no analytics SDK in the binary.
You get cycle and symptom logging, predictions calculated on-device from your own history, and a calendar view. Nothing is uploaded, so nothing can be subpoenaed, breached, or sold from a server, because there is no server.

FAQ
Is there a subscription?
No. Where an app has a paid tier it is a one-time in-app purchase that unlocks the app permanently, with Family Sharing enabled.
I paid and the app still shows the paywall.
Open the app's settings and tap Restore Purchases. If that does not unlock it, email support with the Apple ID email you purchased with.
How do I move my data to a new phone?
App data is stored on-device and is included in an encrypted iPhone or iCloud device backup. Restoring that backup onto the new phone brings it across.
How do I request a refund?
Refunds are handled by Apple, not by the studio. Go to reportaproblem.apple.com, sign in with your Apple ID, and choose the purchase.
