Privacy
Last updated 11 November 2026.
This page describes how the app works today, in plain language. The formal privacy policy, including the name and contact details of the data controller, will be published here before the app is offered for sale.
What you put in
The symptoms, sleep, mood, period and notes you log; the optional first name, year of birth and period status you give at set-up; and the concerns and questions you write for your doctor report. This is health information and we treat it as such.
Where it is kept
On your device, and in a private backup in Google Firebase (Cloud Firestore) that only your account can read or write. You can start without an email address: the backup is then tied to an anonymous account on your device. If you add an email and password, you can restore your log on another device.
What we do not do
- We do not sell your data or share it with advertisers or data brokers.
- We do not show adverts.
- Your patterns are worked out on your device. Your log is not sent to an AI service.
Who processes data for us
- Google Firebase: sign-in, the private backup of your log, and hosting of this website.
- Apple, Google and RevenueCat: if you subscribe in the mobile apps, they handle the purchase. They receive an account identifier and purchase details, never your health log.
Deleting your data
In the app, open More and choose Delete my account and all data. This permanently removes your log, your report notes and your account from your device and from the backup. Deleting your data does not cancel a subscription; cancel that in your App Store or Google Play account.
Not medical advice
TrackPeri is not a medical device and does not provide medical advice or a diagnosis. It summarises what you log. Always talk to a healthcare professional about your symptoms.
