They are either required to help us improve our service or in-part assist in delivering the service you would expect (in the case of payment processing) or are associated with your session with one of our analytics partners, which in turn helps us understand how you use our services.
An example is Google Analytics, who track your use of our website in order to provide us with analysis reports etc, which in turn help us improve our website. Cookies set by other sites and companies (ie. third parties) can be used to track you on other websites that use the same third-party service.

If you browse websites from multiple devices, you may need to update your settings on each individual device.
