This page explains the cookies and local-storage entries we use, why we use them, and how to manage your preferences. Our wider Privacy Policy covers the rest of how we handle your data.
Two categories
- Essential. Needed for the site to work — sign-in, basket, and remembering your cookie choice. These are not subject to consent because the service can’t run without them.
- Analytics (optional). Help us understand how the site is used so we can improve it. Only set if you click “Accept all” on the cookie banner. We do not use advertising, marketing, or third-party tracking cookies.
