If you Sign in with Apple, we receive an opaque Apple user identifier and (optionally) an Apple-relay email. When you purchase Migraine Map Pro, Apple shares an anonymous StoreKit transaction so we can confirm your subscription is active — no card or address information ever reaches us.
Attack logs, daily signals, medications, sleep, weather, menstrual-cycle phase and trigger data are stored in SwiftData on your device. If you Sign in with Apple or buy Pro, we process only the account and transaction identifiers needed to provide that service.
If you grant Migraine Map permission, we read sleep duration, heart-rate variability, resting heart rate, blood-oxygen, menstrual cycle phase, and headache-symptom samples to feed your on-device trigger correlator. We write headache attack logs back to Apple Health so your other apps can see them. None of this Health data is transmitted off-device under our control. We do not use the Clinical Health Records API.
We query the Apple WeatherKit service for barometric pressure, humidity, UV, and temperature forecasts using only your approximate locality. Location is not recorded with your attack logs. Your precise location is never stored.
We use Apple for authentication, StoreKit subscriptions, WeatherKit, and HealthKit permission prompts. We use Cloudflare for support pages, subscription verification, and optional authenticated APIs. We use no third-party advertising, tracking, or analytics SDKs inside the app.
Optional pattern-explanation features may send a short de-identified summary of correlator output to a backend large-language-model provider for plain-English explanation. No raw attack logs, no Apple Health samples, no identifiers are sent. Responses are returned and not retained on our side.
You can delete your local migraine history at any time from Settings > Delete My Data. If you used Sign in with Apple or purchased Pro and want server-side identifiers removed where legally permitted, email mitsi@uptrail.ai.
Migraine Map is intended for adults. We do not knowingly collect data from anyone under 13. If a minor under 13 uses Migraine Map, a parent should email us to request deletion.
