There are a number of types of cookies: session cookies, persistent cookies, first-party cookies and third-party cookies.
Session cookies: These cookies link your actions on this website to our data system and are used for a number of reasons, such as remembering which pages you visited while browsing this website. The session cookies expire as soon as the browser is closed, so no information is stored permanently.
Persistent cookies: These cookies remember your preferences or actions across this website and help us to provide you with information that is relevant to you in the future. The information collected can be used to track actions across multiple browser sessions.
First-party cookies: These cookies are set and handled directly by us. They cannot be accessed or read by any other website.
Third-party cookies: These are cookies for which we have given a separate website permission to use on this website. They allow the separate website to record certain actions you take on this website. Google collect cookies, as specified below.
Categories of Cookies.
The cookies used on this website can be categorized as follows:
Strictly necessary. Strictly necessary cookies let you move around a website and use its features. Without these cookies, services you have asked for (such as navigating between pages or submitting online forms) cannot be provided. These cookies are essential for the website to function properly.
Performance. Performance cookies collect information about how you use our website, such as which pages you visit and if you experience any errors. These cookies allow us to provide a high-quality experience by customising our offering and quickly identifying and fixing any issues that may arise.
Third Party Cookies. See section below on Interaction with External Social Networks and Platforms.
A web beacon (also known as a tag, clear gif or 1×1 pixel) is a small graphic image place in the code of a web page. These small images embedded in web content and HTML-formatted email messages are ordinarily not visible to users. Like cookies, this technology enables us to track traffic patterns of visitors as they navigate the site or to determine whether content was viewed. Web beacons also allow us to determine whether emails have been opened or links accessed, and identify aggregate trends, individual usage, and generate statistics about how our Site is used.
If you would prefer not to have web beacons in the emails that you receive, you should configure your email software to disable HTML images or refuse HTML email (selecting the option for text only viewing). Setting your browser to decline cookies or to prompt you for an opt-in response before cookies are set will also reduce web beacons’ functionality.
