Cookies

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

For example, we keep track of the domains from which people visit and we may also measure visitor activity on the Pythagoras website, 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, to look at pages that users appear to be finding useful (and those they may not), and to monitor what devices our website is being viewed on in order for us to ensure that our site is usable on as many devices as people are using to view it.

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 areas 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 a small text file that a website can send to your browser, which may then be stored on your hard drive.

The Pythagoras websites use 7 cookies to facilitate user experience and anonymous visitor metrics:

5 third party cookies are set by Google Analytics (GA) – We use GA to gather anonymous information about website visitors to help us make our website experience better. We also use GA in conjunction with site search data to identify how often content is searched for and accessed. Allowing us to improve existing content and identify where new content is required.

We do not use this information to target advertisements or pass any data to third parties. The site will function without GA cookies. To disable the GA cookies in your browser please follow this link.
