1.The short version
This site stores only what it needs to work: your sign-in, your cart and a few display settings. We don’t use advertising cookies, cross-site tracking, or third-party analytics. Google’s reCAPTCHA sets its own cookies to protect the site from bots.

3.Necessary, security and preference storage
Necessary and security storage makes sign-in, the cart and checkout work and keeps the site safe, so it can’t be switched off on the site. Preference storage only remembers choices you made. None of it is used to build a profile of you or follow you to other sites.
4.Your controls
You can clear or block cookies and site data in your browser’s settings. If you do, you’ll be signed out, your cart will empty and your display settings will reset. Signing out also ends your session on this browser. More about how we handle information is in our Privacy Policy.
