This cookie name is associated with Google Universal Analytics - which is a significant update to Google's more commonly used analytics service. This cookie is used to distinguish unique users by assigning a randomly generated number as a client identifier. It is included in each page request in a site and used to calculate visitor, session and campaign data for the sites analytics reports. By default, it is set to expire after 2 years, although this is customisable by website owners.
We use Google Analytics to collect information about how people use this site. For example, what you click on, how long you spend on the site and how you got here. We do this to make sure the site is meeting its users’ needs and to understand how we can improve it. This information cannot be used to identify who you are. We do not allow Google to use or share our analytics data.
