Your cycle is nobody’s business but yours.

Circle was designed so that the most private data you have never has to leave your phone. This page explains exactly what that means.

No accounts, no sign-up

Circle does not ask you to create an account, provide an email address, or identify yourself in any way. You download the app and start using it.

Your data stays on your device

Everything you log — cycle dates, insertion and removal events, check-ins, symptoms, and settings — is stored locally on your iPhone. Circle has no server that receives your cycle data, and the app works fully offline. Your data is never sold, shared, or used for advertising.

Notifications are local

Reminders are scheduled directly on your device using Apple’s local notification system. No reminder ever passes through an external service.

Purchases

Circle Pro subscriptions are processed by Apple and managed through RevenueCat, which receives an anonymous app identifier and purchase history to validate your subscription. This data is not linked to your identity and contains none of your health or cycle information.

No tracking, no ads

Circle contains no advertising, no third-party trackers, and no analytics that profile you.

Deleting your data

Because your data lives only on your device, deleting the app deletes your data. There is nothing to request and no one to ask.
