To make this site work properly, we sometimes place small data files called cookies on your device. Most large websites also do this.
What are cookies?
A cookie is a small text file that a website stores on your computer or mobile device when you visit it. It allows the web server to remember your actions and preferences (such as login, language, font size and other display preferences) for a period of time so you don’t have to re-enter them whenever you return to the site or navigate from one page to another.
How do we use cookies?
Some of our sites use cookies to remember you:
- your display preferences, such as contrast colour settings or font size
- if you have already responded to a contextual survey window that asks you whether or not the content was helpful (so no one asks you anymore)
- if you have agreed (or disagreed) to our use of cookies on this website
Some videos embedded on our site also use a cookie to anonymously collect statistics about how you got there and what videos you have visited.
Allowing these cookies is not strictly necessary for the website to work, but will give you a better browsing experience. You can delete or block these cookies, but if you do, some features of this website may not work as intended.
The information associated with cookies is not used to personally identify you and the pattern data is completely under our control. These cookies are not used for any purpose other than as described herein.
Do we use other cookies?
Some of our sites or sub-sites may use additional or different cookies than those described above. If this is the case, details of these will be provided on their specific cookie notice page. You may be asked to consent to the storage of these cookies.
How to control cookies
You can control and/or delete cookies at your own discretion – see aboutcookies.org for details. You can delete any cookies that are already on your computer, and you can set most browsers to not allow them. However, if you do this, you may have to manually adjust some preferences each time you visit the site and some services and features may not work.
