What do cookies do?

Cookies are small (text) files placed on your computer or other electronic device by a webpage server when you visit a webpage. By placing a cookie on your device, the webpage server can recognise your device. A cookie cannot start programmes or spread viruses.

Cookies have a certain time limit from the moment they are placed on your device. After that time limit, the cookie is deleted by your browser. Some cookies remain valid for the duration of the browser session, but there are also cookies that remain valid for a longer period of time so that they can also be read during a subsequent visit to the website.

Both functional (i.e. necessary) cookies and analytical cookies are placed by this website. The use of tracking cookies requires your prior consent.

We use a cookie opt-out; a button to accept cookies. These cookies are stored on our server without the possibility to use them to gather information.

These are used to store status data during a particular session. These cookies are stored in cache memory for as long as a user visits the web server issuing the session cookie, and are deleted from the cache when the session is closed.

Permanent cookies

YouTube’s privacy statement (which may change regularly) tells you what they do with your personal data that they may process using these cookies.
