When optional analytics are enabled, Google Analytics is loaded only after you choose “Accept analytics”. If you choose “Only necessary”, no analytics tag is loaded and the site works normally.
Analytics measures page visits and a small set of product events: matcher started, matcher completed, recommended product identifiers, shortlist copied, review opened and vendor-domain click. It does not collect your name, email, free text or individual matcher answers. Advertising storage, signals and personalization are disabled.
Your choice is stored in local storage on the device and can be changed through “Privacy choices” in the footer.
