How/why the homepage uses cookies

Cookies are necessary for the homepage to function. Cookies help us get an overview of your visit to the homepage so that we can continually optimise and adjust the homepage to your requirements and interests. For example, cookies remember what you might have added to a shopping cart, if you have previously visited the page, if you are logged in and what languages and currency you want displayed on the homepage. We also use cookies to target our ads to you on other homepages. On a very general level, cookies are used as part of our services in order to show content that is as relevant as possible to you.

How long are cookies saved?

How long cookies are saved on your device can vary. The time when they are scheduled to expire is calculated from the last date you visited the homepage. When cookies expire, they are automatically deleted. You can view a complete list of cookies below.

This is how you can reject or delete your cookies

You can always reject cookies on your computer, tablet or phone by changing your browser settings. Where these settings can be found depends on the type of browser you are using. If you do change the settings, please be aware that there will be some functions and services that you cannot use because they rely on the homepage being able to remember the choices you have made.

You can choose to not receive cookies from Google Analytics here.
