Aggregate page analytics
Cloudflare Web Analytics records aggregate page views, visits, referrers, countries, browsers and page performance. It does not use cookies, local storage or cross-site tracking for this site.
Comparison and product pages
Product filters and comparison choices are handled as page requests. We do not ask for names, email addresses or account registration to use the catalogue, comparisons or evidence API.
Commercial measurement
Retailer redirects increment daily aggregate counters for the product, category, retailer, page context, affiliate state and a small allowlist of referral channels. The counters do not store an IP address, visitor identifier, cookie, search query or raw referrer URL.
Human page views, known buying-agent requests and crawler fetches are reported separately. Calls to the direct agent tools increment a daily counter for the tool name without storing the query, product ID or response. The resulting event-rate report is available as aggregate traffic JSON. Commercial performance is operationally separate from evidence collection, purchase eligibility, scoring and ranking.
Known automation is classified from request headers. A separate browser-navigation counter records document requests and activated retailer links. These signals are estimates of activity, not verified people or sales. Calculator inputs stay in your browser and are not sent to our traffic counters.
