What we collect
Rhythma does not create an account and does not upload your cycle data to a server.
Period days, settings, and related cycle data are stored on this iPhone only.
Calendar
If you turn on Calendar sync and grant permission, Rhythma reads calendar events on the device so they can be shown next to your cycle. That data stays on the iPhone. Rhythma does not send it to a server.
Why Full Access? iOS calls this “Full Access” because it does not provide a read-only Calendar permission. Rhythma only reads events to show them in the app. It does not create, edit, or delete your calendar events.
Purchases and subscriptions
Rhythma Plus is an optional auto-renewable subscription (monthly or yearly) purchased through Apple.
- Payment is charged to your Apple ID via the App Store. Rhythma does not collect, store, or process your payment card details.
- Apple may share limited purchase status with the app so Plus features can unlock. That status stays on-device; Rhythma does not run its own billing server.
- Manage or cancel in iPhone Settings → Apple ID → Subscriptions.
- Use Restore purchase in Rhythma Settings if you reinstall or switch devices while subscribed.
Terms of Use (EULA): Apple Standard Licensed Application End User License Agreement
Analytics and ads
Rhythma does not use advertising SDKs and does not sell personal data.
Deleting data
Delete the app to remove locally stored cycle data. There is no Rhythma cloud backup to request or erase. Cancelling a subscription does not delete on-device cycle data; deleting the app does.
