Crumbs we keep
Short version: the jar is empty. This site works without setting cookies, and there is no banner because there is nothing to consent to.
What this site sets
Nothing. The pages are static files, the picker runs in your browser without phoning anywhere, and closing the tab ends the exchange.
No third party analytics rides along either. We count nothing about your visit.
What happens after a buy button
Following a buy button takes you to the retail partner, and their site sets cookies under their own policy from that point. Their cookie page describes that machinery.
The boundary is the click. On this side of it, your browser stays as it arrived.
