We make use of analytical cookies through Google Analytics. These cookies help us compile anonymous statistics that allow us to understand how visitors are using our web site, which pages are being visited, and help us improve it and its content. These cookies do not identify visitors personally.
Our use of Google Analytics will set the following cookies on your device (information taken from http://code.google.com/apis/analytics/docs/concepts/gaConceptsCookies.html)
__utma: This cookie is typically written to the browser upon the first visit to your site from that web browser, and is used to determine unique visitors to a site and is updated with each page view
__utmb: This cookie is used to establish and continue a user session with your site. When viewing a page, the Google Analytics code attempts to update this cookie. If it does not find the cookie, a new one is written and a new session is established. Each time a user visits a different page on your site, this cookie is updated to expire in 30 minutes, thus continuing a single session for as long as user activity continues within 30-minute intervals.
__utmc: Historically, this cookie operated in conjunction with the __utmb cookie to determine whether or not to establish a new session for the user.
__utmz: This cookie stores the type of referral used by the visitor to reach your site, whether via a direct method, a referring link, a website search, or a campaign such as an ad or an email link. It is used to calculate search engine traffic, ad campaigns and page navigation and is updated with each page view.
Google offers an opt-out tool available at https://tools.google.com/dlpage/gaoptout which allows you to opt out of all their Analytics tracking for all web sites as an add-on to most popular browsers
