- a) Our cookies
|_utma||Our Site uses Google Analytics, a web service provided by Google. Google Analytics sets 4 cookies in order to evaluate your use of the Site.
Google stores the information collected by the cookies on servers located in the United States. Google may also transfer this information to third parties where required to do so by law, or where such third parties process the information on Google’s behalf. Google will not associate your IP address with any other data held by Google.

The _utma cookie keeps track of the number of times a visitor has been to the site pertaining to the cookie, when their first visit was, and when their last visit occurred.
|The _utmb and _utmc cookies are brothers, working together to calculate how long a visit takes. _utmb takes a timestamp of the exact moment in time when a visitor enters a site, while _utmc takes a timestamp of the exact moment in time when a visitor leaves a site. _utmb expires at the end of the session. _utmc waits 30 minutes and then expires. You see, _utmb has no way of knowing when a user closes their browser or leaves a website, so it waits 30 minutes for another page view to happen, and if it doesn’t, it expires.|
|_utmz||_utmz keeps track of where the visitor came from, what search engine you used, what link you clicked on, what keyword you used, and where they were in the world when you accessed a website. It expires in 6 months. This cookie is how Google Analytics knows to whom and to what source/medium/keyword to assign the credit for a Goal Conversion or a Ecommerce Transaction. _utmz also lets you edit its length with a simple customisation to the Google Analytics Tracking code.|
