## FAQ

### What are cluster headaches?

Cluster headaches are severe one-sided headache attacks that often occur in cycles and can repeat at similar times of day.

### How do users share reports with a doctor?

Users generate a secure, temporary share link that shows charts, tables, medication notes, and logged attacks without requiring the doctor to create an account.

### Can users export their data?

Yes. Users can export their headache logs as CSV.

### Is personal headache data exposed to AI crawlers?

No. AI-visible resources describe only public product pages and public product facts, not private headache logs or shared reports.
