A cookie is a small file, typically of letters and numbers, downloaded on to a device when the user accesses certain websites. Cookies allow a website to recognise a user’s device and track users as they navigate different pages on a website and to identify users returning to a website. Cookies do not contain any information that personally identifies you, but personal information that we store about you may be linked, by us, to the information stored in and obtained from cookies.
Session and persistent cookies
Cookies can expire at the end of a browser session (from when a user opens the browser window to when they exit the browser) or they can be stored for longer.
- Session cookies – allow websites to link the actions of a user during a browser session. These session cookies expire after a browser session so would not be stored longer term. For this reason session cookies may be considered less privacy intrusive than persistent cookies.
- Persistent cookies – are stored on a users’ device in between browser sessions which allows the preferences or actions of the user across a site (or in some cases across different websites) to be remembered.
First and third party cookies
Whether a cookie is ‘first’ or ‘third’ party refers to the website or domain placing the cookie.
- First party cookies in basic terms are cookies set by a website visited by the user / the website displayed in the URL window.
- Third party cookies are cookies that are set by a domain other than the one being visited by the user. If a user visits a website and a separate company sets a cookie through that website this would be a third party cookie.
