Peri Diary

Privacy policy

Last updated 15 October 2026.

Peri Diary keeps your symptom log, notes, HRT details and reminders on your iPhone. We do not run a server that receives them. There is no account and no sign-in.

The app does not use analytics, advertising or trackers.

Purchases are processed by Apple. The app checks your purchase with RevenueCat, using an anonymous app user ID, so Peri Diary can unlock on your iPhone and restore on a new one. Nothing else is collected or sent.

Notifications are local to your iPhone and are used only for the reminders you turn on. They are not sent through a server.

To take your data out, use the export or report option in Settings. To delete everything, use Settings, then Delete all data. Deleting removes it from your iPhone.
