'Session cookies' allow us to track your actions during a single browsing session, but they do not remain on your device afterwards.
'Persistent cookies' remain on your device between sessions. We use them to authenticate you and to remember your preferences. We can also use them to balance the load on our servers and improve your experience on our site.
Session and persistent cookies can be either first or third party cookies. A first-party cookie is set by the website being visited; a third-party cookie is set by a different website. Both types of cookie may be used by us or our business partners.
