Although cookies cannot carry viruses, and cannot install malware on the host computer, tracking cookies and especially third-party tracking cookies are commonly used as way to compile long-term records of individuals' browsing histories - a major privacy concern that prompted European and US law makers to take action.
Cookies we use:
Session Cookies (PHPSESSID)
We use session cookies to record an individual users preferences that the user has specified, so that each time the user returns their preferences remain. Commonly this would be language settings, shopping carts, anything where you have indicated a preference. Where forms are used on the site, we hold the information in a session cookie so that we can improve the user experience on the site. Should a user, for example, forget to fill in parts of a form when submitting a form, we can auto-fill the values for those fields that have been filled in, thereby reducing the amount of fields a user needs to amend. This information is stored only in your browser and is destroyed once your browser is closed.
