How do I manage Apple Health permissions?

Migraine Navigator can integrate with Apple Health to read sleep patterns, resting heart rate, heart rate variability, and physical activity. It can also write logged headache episodes to your Apple Health record if enabled.

To change or re-authorize permissions at any time, open your iPhone Settings → Privacy & Security → Health → Migraine Navigator and adjust the desired categories.

How does weather information work?

The application queries Apple WeatherKit for local atmospheric conditions, including barometric pressure trends. Location coordinates are transmitted directly to Apple's WeatherKit service during active forecast checks to retrieve current atmospheric readings. Location coordinates are saved locally with your logs to provide environmental context. The app does not perform continuous background route tracking and location is never stored by or transmitted to the developer or commercial third parties.

How is data synchronized across devices?

If iCloud is active on your Apple account, your local database synchronizes across your iOS devices using Apple CloudKit. Synchronization takes place within your personal private iCloud container. The developer has no access to your iCloud credentials or data.

How do I export my logged data?

You can export your complete episode history at any time. Open the app, go to Settings → Data Management → Export Historical Data (CSV).

The exported file (MigraineNavigator_Export.csv) includes dates, times, pain levels, sleep scores, physical activity, triggers, medications, personal notes, and approximate location. You can share the file via AirDrop, Mail, Files, or Messages.

Can I import historical data from a previous export?

Yes. Go to Settings → Data Management → Import Historical Data and select your compatible CSV export file. The app will import your historical logs while skipping duplicates.

How do I erase my data or reset calibrations?

To permanently erase all logged episodes, custom medication catalogs, and baseline registries from your device, go to Settings → Data Management → Delete All My Data.

To restore factory trigger sensitivity sliders and model weights without deleting your logged episode history, go to Settings → Reset → Reset All Settings & Weights.

What is the Research & Algorithm Accuracy setting?

This optional setting allows you to contribute anonymous, non-identifiable mathematical accuracy and performance statistics to help validate and improve forecasting reliability over time.

It never includes your health records, symptoms, medications, or personal logs. You can turn this setting on or off at any time in Settings → Research & Algorithm Accuracy.

What is the Diagnostic Report?

If you encounter a technical issue (such as weather data failing to refresh), go to Settings → Diagnostics & Support → Export Diagnostic Report.

This exports a sanitized technical file (MigraineNavigator_Diagnostics.json) containing rotating subsystem status codes and recent error traces. It strictly excludes personal health records and GPS coordinates. You can attach this file when contacting developer support.
