Privacy Policy

Last updated November 10, 2026

My Migraines is a migraine diary. It is built so that what you write about your health stays with you.

Your diary stays on your iPhone

Everything you log (migraines, times, intensity, medicines, symptoms, notes) is stored on your device. There is no account and no sign-in. We have no server that holds your diary, so we cannot see it, sell it or hand it over.

Your diary is included in your iPhone's own backup (iCloud Backup or a computer backup), which Apple handles under its own privacy policy.

Apple Health

If you turn on Save to Apple Health, each migraine is written to Health as a Headache, with its times and intensity. The app only writes; it never reads anything from Health. You can turn this off at any time in the app or in the Health app's settings.

Anonymous usage counts

To learn which parts of the app are used, the App Store version sends anonymous usage events to PostHog (servers in the United States). An event is a name such as "report opened", with a few plain details: which button, the app version and the app's language, and a random number created on your phone so events from one install can be counted together.

These events never include anything from your diary: no times, medicines, symptoms, notes or health information. They contain no name, email, Apple ID or advertising identifier, and they are not used for advertising or shared to track you across other apps.

Purchases

Purchases of My Migraines Plus are made through Apple. We use RevenueCat to check whether Plus is active; it receives an anonymous app user ID and the purchase details Apple provides. It receives nothing from your diary.

Exporting and deleting

You can export everything as a spreadsheet file (CSV) from the You tab, and share the doctor's report as a PDF. Both are created on your phone and go only where you send them.

You can delete your whole diary from the You tab (Delete All Data), which also removes the entries the app wrote to Apple Health. Deleting the app removes the diary from your phone.

Children

My Migraines is not directed at children under 13.
