Privacy Policy

Migra is built on a simple principle: your migraine data belongs to you, and only you. This page explains what that means in practice.

Data we collect

None of your migraine data is collected, stored, or transmitted by us. Specifically:

• Attack logs, triggers, medications, intensity levels: stored locally on your device using SwiftData. Never uploaded.
• Location: used only to fetch local barometric pressure forecasts via Apple WeatherKit. Coordinates never leave your device.
• Apple Health data: read on-device to correlate sleep, steps, and heart rate with attacks. Never uploaded.
• AI insights: processed entirely on your device using Apple Foundation Models. No cloud inference.

Subscription and analytics

For subscription management we use RevenueCat (purchase confirmation, restore purchases). RevenueCat receives only the App Store transaction ID \u2014 never your migraine data.

For aggregated, anonymous usage analytics (e.g., "how many users tapped the paywall this week") we use TelemetryDeck. TelemetryDeck does not collect personal data and stores only hourly counters in privacy-preserving aggregates. No migraine data, no health data, no precise location.

For crash reports we use Sentry. Crash reports contain stack traces but no personal or health data.

Account and identifiers

Migra does not require an account. We do not collect your name, email, or phone number.

Apple Search Ads attribution

If you arrive via an Apple Search Ads campaign, an attribution token may be exchanged with RevenueCat to attribute the install. This is anonymous and does not require ATT consent.

Data deletion

Delete the app from your iPhone to delete all your migraine data. Because nothing leaves your device, nothing remains anywhere else.
