Cookies are technologies used to store and read information from devices such as computers and mobile devices. Cookies are typically used in order to make websites function, or function more eﬃciently. Without Cookies, every website is simply losing its memory every time you visit a new page and open up the website again. Websites wouldn’t remember who you are and what you did or what your preferences are. This can be fairly complicated as much of the user experience you are used to enjoying on the internet when browsing would cease to exist. Without this memory we, for example, couldn't log you in as we’d forget who you are. Or we couldn’t show you the right language settings because we wouldn’t know where you are coming from. All these useful functionalities which make websites so enjoyable wouldn’t be available.
