Measuring what health-care websites tell advertising platforms

HealthPixel Check opens a public US health-care website in a clean browser and records which advertising, analytics, session-replay, call-tracking and chat services receive data, such as the Meta Pixel or Google Ads tags, before and after the cookie choice, and whether page addresses or titles that name a condition or treatment are sent along. Under HIPAA and FTC rules this is a compliance question; the check measures what actually leaves the page and leaves the legal judgement to you. The checker is free, and the engine behind it is open source.

• Before and after consentNo choice, after “Accept”, after “Reject”, with Global Privacy Control, and a direct visit to a service page.
• Who receives dataAdvertising, analytics, session-replay, call-tracking and chat services, including ones behind the site’s own subdomains.
• Findings go to the organizationThe public summary shows vendors and counts, not exact pages. A link to the full report, valid for 72 hours, is e-mailed only to an address at the checked site’s own domain.
