A cookie is a small text file that a website stores on your device (computer, tablet or mobile) when you visit. Cookies serve different purposes: some are essential for the website to function correctly, while others help us understand how visitors use the site so we can improve it.
Cookies set by the website you are visiting are called first-party cookies. Cookies set by other companies whose services are embedded in the website (such as analytics tools) are called third-party cookies.

We do not use cookies for advertising or to track you across other websites.
