Cookies are files containing small amounts of information which are downloaded to the device you use when you visit a website. Cookies are then sent back to the originating website on each subsequent visit, or to another website that recognises that cookie. Cookies do lots of different and useful jobs, such as remembering your preferences, and generally improving your online experience.
There are different types of cookies. They all work in the same way, but have minor differences:
Session cookies last only for the duration of your visit and are deleted when you close your browser. These facilitate various tasks such as allowing a website to identify that a user of a particular device is navigating from page to page, supporting website security or basic functionality.
Persistent cookies last after you have closed your browser, and allow a website to remember your actions and preferences. Sometimes persistent cookies are used by websites to provide targeted advertising based upon the browsing history of the device.
First and third party cookies
Whether a cookie is a first or third party cookie depends on which website the cookie comes from. First party cookies are those set by or on behalf of the website visited. All other cookies are third party cookies.
Strictly necessary cookies

Without these cookies, services you have asked for, such as adding items to the shopping cart, or logging into your account cannot be provided. These cookies don’t gather information about you for the purposes of marketing.
These cookies collect information about how visitors use a web site, for instance which pages visitors go to most often, and if they get error messages from web pages. These cookies don't collect information that identifies a visitor although they may collect the IP address of the device used to access the site.
