What are cookies?
Cookies are small text files that the web sites you visit place on your computer to store information about your visit. Cookies are 'passive' in that they contain information your browser can retrieve, but do not contain programmes, viruses or malicious software. Cookies normally expire after a certain length of time, although that time can be anywhere from a few minutes to more than a year.
Cookies can be divided into two categories: 'session' and 'persistent'. Session cookies are temporary and are deleted when you close your browser or after a period of inactivity. Persistent cookies remain on your computer until the expiration date/time set by the cookie creator.
What do cookies do?
Cookies can contain many types of information about your visit to a particular web site, but most commonly are used to store the preferences you've selected, such as language, shopping cart contents, privacy settings and login state. Cookies do not contain personal or private data about you, but can compile information about your browsing habits. For the most part, cookies enhance your browsing experience by keeping you from having to select the same options each time you visit a site.
However, cookies can also be used by web sites to serve you advertising targeted to your particular interests based on the preferences you've selected or the content of the pages you have visited. For this reason, some web users choose to delete or reject cookies of certain types or from certain sites.
Can I delete cookies?
Yes, you can both view the cookies stored on your computer and delete some or all of them. However, each browser has a slightly different procedure for doing so.
Note that in some cases, deleting cookies will impact your experience in revisiting a site.
Can I set my browser to block cookies?
Yes, most browsers allow you to specify which types of cookies you will accept or to reject all cookies. Each browser is different. You will therefore need to check with your browser provider to find out how to disable or enable cookies.
As above, you may see an alert message when visiting sites that recommend you accept cookies for an optimal browsing experience.

Which cookies does this site use?
Most cookies you will encounter when browsing this website are considered 'third party' cookies. This means this site has used a feature supplied by an external provider, such as Google Maps which sets the cookie. Third party cookies are not inherently more or less risky than first party cookies. The only thing to bear in mind is that the external provider, not UCL IOE, determines what type of information is stored and how it is used.
This website uses first party cookies set by Google Analytics, which provides anonymous statistical data to us to show usage trends.
