What cookies are
Cookies are small text files placed on a visitor's device by a website. They allow the site to remember information between pages or across visits, such as preferences or session state.
Similar technologies — including local storage and pixels — operate in comparable ways, and they are treated under this policy alongside cookies. In each case a small piece of data is stored on your device so the site can recognise it later. None of it changes anything on your device, and none of it is read by anything other than the site that set it.
