Cookies are small text files that can be used by web sites to make a user's experience more efficient.

The law states that we can store cookies on your machine if they are essential to the operation of this site but that for all others we need your permission to do so.
We use essential cookies (called session cookies) designed to guarantee a friendly and rich user experience. This type of cookies does not store any personal information about the user.

Our website does use some non-essential cookies. We do not do this to track individual users or to identify them, but to gain useful knowledge about how the site is used so that we can keep improving it for our users. Without the knowledge we gain from the systems that use these cookies we would not be able to provide the service we do.

We use Google Analytics, a popular web analytics service provided by Google, Inc. Google Analytics uses cookies to help us to analyse how users use the site. It counts the number of visitors and tells us things about their behaviour overall – such as the typical length of stay on the site or the average number of pages a user views.

The information generated by the cookie about your use of our website (including your IP address) will be transmitted to and stored by Google on servers in the United States. Google will use this information for the purpose of evaluating your use of our website, compiling reports on website activity and providing other services relating to website activity and internet usage.

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 undertakes not to associate your IP address with any other data held by Google.

If you have Adobe Flash installed on your computer (most computers do) and you use audio or video players within our website, Google Analytics will try to store some additional data on your computer. This data is known as a Local Shared Object or Flash cookie. This helps us to analyse the popularity of our media files. We can count the total number of times each file is played, how many people watch videos right to the end and how many people give up half way through. Adobe's website offers tools to control Flash cookies on your computer.

If you want to delete any cookies that are already on your computer, please refer to the instructions for your file management software to locate the file or directory that stores cookies. You can access them through some types of browser.
