What we collect
This site is a static website. It does not create user accounts, host comments, or accept uploads. It collects the minimum information needed to keep the site online and to understand traffic:
- IP address, request headers, and browser user agent, processed by Cloudflare as our CDN and DDoS protection provider.
- Aggregate, cookie-free traffic analytics from Cloudflare Web Analytics (page views, referrers, country).
- Aggregate, cookie-free usage analytics from Google Analytics and PostHog (page views, referrers, approximate country, which links are clicked). Both run in a mode that stores no identifier on your device, so we cannot recognise you across visits. Google Consent Mode is set to deny all storage for visitors in the EEA, UK and Switzerland. PostHog session recording is disabled and PostHog data is processed in the EU.
- Email address and message contents you voluntarily send to the addresses listed on this site.
