What cookies are
Cookies are small text files that a website stores in your browser. They let the site remember things between visits, your preferences, that you have already given consent, and (where you allow it) information used for analytics and advertising. Similar technologies like local storage and pixel beacons work the same way for the purposes of this policy.
