Cookie Policy

In order to ensure the best possible experience for users it is necessary to collect some anonymous information on usage behaviour. Google analytics makes use of a number of cookies to identify unique users and records information such as screen size, time spent on a page and geographical location. All this information allows the site to adapt, improve content and localise to its visitors.

Our implementation of Google Analytics makes use of the following 4 cookies which are described by Google as follows:

Determining Visitor Session (__utmb and __utmc)

The Google Analytics tracking for ga.js uses two cookies to establish a session. If either of these two cookies are absent, further activity by the user initiates the start of a new session.

Identifying Unique Visitors (__utma)

Each unique browser that visits a page on your site is provided with a unique ID via the __utma cookie. In this way, subsequent visits to your website via the same browser are recorded as belonging to the same (unique) visitor. Thus, if a person interacted with your website using both Firefox and Internet Explorer, the Analytics reports would track this activity under two unique visitors. Similarly if the same browser were used by two different visitors, but with a separate computer account for each, the activity would be recorded under two unique visitor IDs. On the other hand, if the browser happens to be used by two different people sharing the same computer account, one unique visitor ID is recorded, even though two unique individuals accessed the site.

Tracking Traffic Sources & Navigation (__utmz)

When visitors reach your site via a search engine result, a direct link, or an ad that links to your page, Google Analytics stores the type of referral information in a cookie. The parameters in the cookie value string are parsed and sent in the GIF Request (in the utmcc variable). The expiration date for the cookie is set as 6 months into the future. This cookie gets updated with each subsequent page view to your site; thus it is used to determine visitor navigation within your site.

By continuing to use this site you accept our use of these cookies on your system.
