This Cookie Policy explains what cookies are and how we use them. This policy is part of our Privacy Policy, which explains how we use your personal information, including personal information collected via cookies. If you would like to manage your cookie preferences, please follow the instructions in the “How can I manage cookies?” section below.

What are cookies and how do we use them?

We use the term ‘cookies’ in this policy to refer to all files that help us recognize your device when you visit one of our websites and to distinguish you from other users. These cookies can be small text files that are downloaded to the browser of an internet-enabled device – such as your computer, smartphone or tablet – or they can be web beacons/pixels that are stored locally on your device. Cookies can also be placed when you open emails from us that contain images, or you visit third-party websites that send us information.

Some cookies are strictly necessary to enable our website’s technical features. Other cookies are useful, for example, they allow us to recognize your device when you browse our websites and then store and manage your preferences. This enables us to provide you with a better website experience. They also enable us to collect statistics and user data, so that we can improve our websites and emails. This helps us to deliver targeted advertising.

We want you to be able to make an informed decision for or against the use of cookies, which are not strictly necessary for the website’s technical features, based on the options below:

  • Strictly necessary
    These cookies enable functions, which are necessary for the website’s intended operation. They typically provide you with services you request, such as logging in, setting your privacy preferences or filling in forms. User consent is not required for the use of strictly necessary cookies, and their use cannot be disabled using the functionality of this website. See the “How can I manage cookies?” section below to understand how to disable cookies in your browser.
  • Performance
    These cookies collect information about how often you visit and how you use our websites. For instance, we collect information about which pages visitors go to most, or where error messages appear. This aggregated and anonymous information is used to optimize content and improve our website. If you don’t allow these cookies we won’t know when you have visited our website and won’t be able to monitor its performance.
  • Functional
    These cookies allow our websites to remember information such as your log-in details, language preference, or geographic region. This information is used to provide a more personalized experience and to make the website easier to use. If you don’t allow these cookies, then some or all features may not function. In some cases, if you choose to interact with a feature after you have chosen to disable functional cookies, they can be reactivated.
  • Advertising
    These cookies allow us to display advertising we think is relevant to you. We build profiles based on your browsing history, which we share with our advertising partners to show you relevant advertisements on other sites. If you don’t allow these cookies you will still receive advertising, but it will be less relevant.

What are third-party cookies

Some cookies are set by websites owned by third parties, known as “third-party cookies”. For example, some of our websites allow Facebook to place its cookies on your web browser if you have given Facebook permission to do this. If you have visited one of our websites and you also use Facebook, Facebook can identify you as someone who is interested in our products and show you advertising from us when you return to Facebook.

Some of our websites include social media sharing features, such as the Facebook “Like” button or the X “Tweet” button. If you use these features, these third parties may place cookies to enable the features to function properly. We do not control how social networks collect and use your personal information and its use is subject to the social network’s own privacy policy:

Third-party cookies are also used to track the effectiveness of our advertising on other websites. For example, if you click on one of our advertisements on another company’s website, the owner of that site might use a cookie to tell us that you came from their website.

We use the remarketing function of Google Inc. ("Google") on our website. This feature is implemented with cookies and is used to show interest-based advertisements to visitors on sites of the Google Advertising Network. On these pages, visitors can be shown advertisements that refer to the interaction the visitor had previously on our website. For more information on this, and to manage your preferences, visit: For more information about Google Remarketing and the Google Privacy Policy, please visit:
