What cookies are
Cookies are small text files a website stores in your browser. Some are essential for a site to function — keeping you signed in, remembering a basket — while others measure how a site is used.
What we do not use
We set no advertising cookies, no social media pixels and no cross-site tracking of any kind. We do not sell or share browsing data with advertisers.
Managing cookies
Every major browser lets you block or delete cookies from its privacy settings. Blocking functional cookies will still let you browse, but your basket, theme and currency choices will reset on each visit.
Changes to this policy
If we add or remove a cookie we will update the table above and the date below. Material changes are also announced in The Margin Note newsletter.
