  • How we use cookies on our website

    We sometimes collect anonymous information from visits to our site to help us provide a better service.

    For example, we may keep track of how people find and use our website and we may also measure visitor activity, but we do so in ways that keep the information anonymous.

    We use the information that we collect to measure the number of visitors to the different areas of our site, and to help us make our site more useful to visitors.

    This includes analysing these logs periodically to measure the traffic through our servers, the number of pages visited and the level of demand for pages and topics of interest.

    The logs may be preserved indefinitely and used at any time and in any way to prevent security breaches and to ensure the integrity of the data on our servers.

    We collect this anonymous information through the use of various technologies, one of which is called "cookies". A cookie is small snippet of text that a Web site can send to your browser, which may then be stored on your hard drive.
