What are cookies?
Cookies are small files saved on your computer by your web browser (such as Internet Explorer, Firefox, Chrome or Opera) at the request of a website you visit. They let the website remember things about you, such as preferences and history, or keep you signed in so you do not have to enter your login and password on your next visit.
Cookies may remain on your computer briefly, for example while the browser is open, or for longer periods, even years. Cookies set by other websites are not accessible to us.

Advertising cookies, possibly from third parties: if the website displays advertisements, advertisers may set cookies to determine who viewed an advertisement and when, or similar information. Third parties may set these cookies, and this website cannot read or write them itself.
