Cookie Policy
Kaizen Detailers — what this website stores in your browser and why.
Last updated 28 October 2026
Cookies are small files a website saves in your browser. Similar technologies — localStorage and sessionStorage — work the same way. We group them by purpose.
Necessary ones are always on: without them the cart, language and sign-in do not work. Analytics and advertising are used only as described below: in the European Economic Area, the UK and Switzerland — only after you agree; elsewhere — until you switch them off. You can change your choice at any time.
