Privacy Policy
Summary
Migraine Days does not collect, sell, share, or track your personal data. The app has no user account, advertising SDK, analytics SDK, or developer-operated server.
Information you enter
Entries such as the days affected by migraine, medication notes, and report preferences are stored locally on your device. The developer cannot access them.
Apple Watch and widgets
If you use the Apple Watch app, the record you create is transferred only between your paired Apple Watch and iPhone through Apple’s Watch Connectivity system. Widgets read a local snapshot shared by the app on your device. This information is not sent to the developer or to a third party.
Reports and sharing
Personal summary PDFs are generated on your device. A summary leaves your device only if you choose to share it using the iOS share sheet. The recipient and sharing method are chosen by you and are governed by their own privacy practices.
Data collection and tracking
Migraine Days does not collect contact information, health or fitness data, location, identifiers, usage data, diagnostics, or purchase history. It does not use tracking, advertising, analytics, cookies, or third-party data brokers.
Data retention and deletion
Your entries remain on your device until you delete them in the app or delete the app. Deleting the app removes its locally stored data as managed by iOS. The developer has no copy to retain or delete.
Children
Migraine Days is not directed to children under 13. We do not knowingly collect personal information from children.
Changes to this policy
If the app’s data practices change, this policy and the App Store privacy information will be updated before the change takes effect.
