Basic operation
Our hosting and content-delivery providers may receive ordinary request metadata such as IP address, requested URL, browser information, and request time. This browser may store the selected light or dark theme locally.
Google Analytics 4
We use Google Analytics 4 with measurement ID G-ZH0X73NJ4R to understand aggregate page usage and navigation. Google Analytics may process page URLs, referrers, browser and device information, interactions, approximate location derived from network information, and first-party analytics identifiers such as the _ga cookie.
Custom events cover use-case selection, catalog filters, length-bucketed searches, exact-product views, researched-guide views, and clicks to merchant Offers. They do not include raw search terms, full merchant URLs, email addresses, or free-form user text.
Our site configuration disables Google Signals and ad-personalization signals. Google processes analytics data under its Privacy Policy.
Your choices
Browser privacy controls, content blockers, or the Google Analytics opt-out browser add-on can restrict analytics. Blocking analytics does not limit access to the catalog, recommendations, evidence, or merchant comparisons.
External links
Opening a manufacturer or merchant link takes you to that provider, whose privacy terms apply independently.
