Analytics
We use Vercel Web Analytics and Speed Insights to count visits and measure page speed. They set no cookies and keep no profile of you, and we strip anything after the page address before a visit is counted. We do not use Google Analytics or session recordings.
Your privacy choices
There is one optional tool: anonymous click heatmaps on eight non-health pages (home, mission, get involved, impact, roadmap, press, partners and the blog index). They record where on those pages people click, with all text hidden. No recordings, no cookies, no form entries, and nothing on CADASIL, caregiving, grants, quiet rooms or any tool or form. They stay off until you turn them on, and a Global Privacy Control or Do Not Track signal keeps them off. The provider is PostHog. Requests pass through our own domain, and PostHog is set to discard IP addresses.
