Analytics
We use Cloudflare Web Analytics, which does not use cookies, does not fingerprint visitors and does not track you across sites. It records aggregate data such as page views, referrer, country and browser type.
Hosting
The site is served by Cloudflare Pages. Cloudflare may process IP addresses in server logs for security and delivery; see Cloudflare's privacy policy.
If you email us, we use your message and address only to reply and delete correspondence when it is no longer needed. Please do not send personal health information.
No accounts, no advertising cookies
We do not offer accounts and currently show no ads. If that changes, this policy will be updated before any cookies are set.
