To make this site work properly, we sometimes place small data files called cookies on your device. Most big websites do this too.
What are cookies?
A cookie is a small text file that a website saves on your computer or mobile device when you visit the site. It enables the website to remember your actions and preferences (such as login, language, font size and other display preferences) over a period of time, so you don’t have to keep re-entering them whenever you come back to the site or browse from one page to another.
- Your display preferences, such as contrast colour settings or font size
- Your activity on the site; this enables us to provide a better experience for all our users
The cookie-related information is not used to identify you personally and the pattern data is fully under our control. These cookies are not used for any purpose other than those described here.
Enabling these cookies is not strictly necessary for the website to work but it will provide you with a better browsing experience. Because we respect your right to privacy, you can choose to change your privacy preferences to prevent non-essential cookies being set.
How to control cookies
You can control and/or delete cookies as you wish – for details, see aboutcookies.org. You can delete all cookies that are already on your computer and you can set most browsers to prevent them from being placed. If you do this, however, you may have to manually adjust some preferences every time you visit a site and some services and functionalities may not work.
