What is a cookie?

Cookies are small text files that contain a small amount of information that is downloaded on your device (e.g. computer, smartphone, or any other electronic device that accesses the internet) when you visit a website or an application. Cookies are then sent back to the original website or application or to other websites or applications that recognize those cookies upon each subsequent visit (with some exceptions, such as for session cookies). Cookies are useful because they allow a website or application to recognize your device and to put this information in connection with other information about you (such as your preferences) and generally help to improve your online experience. Certain cookies will be sent to your device when you visit our website, subject to your consent where required. You can find more information about cookies at and

What types of cookies do we use and how long do they last?

Cookies can be either session cookies or persistent cookies:

  • Session cookies expire when you leave this website and close your internet browser. 
  • Persistent cookies stay in place in your browser even after leaving this website. For instance, a cookie that stores the information to know whether you are a new or a returning visitor is a persistent cookie.
