# Cluster Headache Tracker - Free Tracking by a Fellow Sufferer

URL: https://clusterheadachetracker.com/

> Free, privacy-focused cluster headache tracking built by a fellow sufferer. Log attacks quickly, spot patterns, create doctor-ready reports, and keep health data private.

## Product Summary

Cluster Headache Tracker is a free web, PWA, iOS beta, and Android beta app for people with cluster headaches.
It is built around attack-time use: a large one-tap logging flow captures the attack first, then details can be added later.
The app turns personal logs into charts, tables, CSV exports, and temporary doctor share links.

## Why It Exists

The app was built by Carmine Paolino, a cluster headache sufferer, after paper diaries, spreadsheets, and generic headache apps were too slow during attacks.
Its goal is practical tracking for treatment conversations, including documentation that can support oxygen approval discussions.

## Privacy Position

Accounts use username and password only. Email addresses are not required.
The app has no ads and does not sell user health data.
Personal headache logs and shared reports are intentionally excluded from AI-visible resources.
