Categories of cookies.
Based on what function cookies have and the purpose for which cookies are used, there are four categories of cookie: strictly necessary cookies, performance cookies, functional cookies and marketing cookies.
Strictly necessary cookies
Are essential in order to enable you to move around the website and use its features. Without these cookies, some services cannot be provided – for example, remembering previous actions (e.g. entered text and vehicle configurations) when navigating back to a page in the same session.
Gather information about how a website is used – for example, which pages a visitor opens most often, and whether the user receives error messages from some pages. These cookies do not save information that would allow the user to be identified. The collected information is aggregated, and therefore anonymous. These cookies are used exclusively to improve the performance of the website, and with it the user experience.
Enable a website to save information which has already been entered (such as user names, languages choices, and your location), so that it can offer you improved and more personalised functions. For example, a website can offer your local, price-relevant tax information if it uses a cookie to remember the region in which you are currently located. Functional cookies are also used to enable features you request such as playing videos. These cookies collect anonymous information and cannot track your movements on other websites.
Are used to deliver adverts and other communications more relevant to you and your interests. They are also used to limit the number of times you see an advertisement and to help measure the effectiveness of advertising campaigns. They remember whether you have visited a website or not, and this information can be shared with other organisations such as advertisers (this includes advertising technologies on websites such as Facebook, LinkedIn and Twitter). Cookies for improving group targeting and advertising will often be linked to site functionality provided by other organisations.
