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.
Measuring our visitors
We measure visitors to our website using Google Analytics. This records what pages you view within our site, how you arrived at our site and some basic information about your computer. All of that information is anonymous – so we don’t know who you are; just that somebody visited our site.
The information we collect from analytics helps us understand what parts of our sites are doing well, how people arrive at our site and so on. Like most websites, we use this information to make our website better.
You can learn more about Google Analytics or opt-out if you wish.
Facebook, and other social networks
These services provide social buttons and similar features that we use on our website – such as the “Like” and “Tweet” buttons.
To do so we embed code that they provide and we do not control ourselves. To function their buttons generally know if you’re logged in; for example, Facebook uses this to say “x of your friends like this”. We do not have any access to that information, nor can we control how those networks use it.
Social networks, therefore, could know that you’re viewing this website if you use their services (that isn’t to say they do, but their policies may change). As our website is remarkably inoffensive we imagine this is not a concern.
your display preferences, such as contrast colour settings or font size
if you have already replied to a survey pop-up that asks you if the content was helpful or not (so you won't be asked again)
Also, some videos embedded in our pages use a cookie to anonymously gather statistics on how you got there and what videos you visited.
Enabling these cookies is not strictly necessary for the website to work but it will provide you with a better browsing experience. You can delete or block these cookies, but if you do that some features of this site may not work as intended.
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.
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.
