Managing your cookies
You have a few different options on ways to manage the cookies on your computer or device. You can change your browser settings to prevent cookies from being accepted, or, depending on which browser you are using, you might be able to receive an alert when a website is trying to place one on your browser. With most browsers you can allow first party cookies to be set but refuse third party cookies.
If you decide to change your cookie preferences, you will still be able to browse around the site but please note that some functions will not be available.
The ‘help’ menu on your browser should tell you how to block cookies or change your cookie settings. How you adjust your browsers settings will depend on the browser you are using.
You can delete cookies stored in your browser by using a function in your browser. Whilst this does not mean you won’t collect cookies in the future, it allows you to delete your cookies after you have been online. This operation is known as ‘clearing cookies’.
Clearing your cookies on one browser of one device does not automatically clear them on another. You will need to clear all browsers on all channels independently.
