Cookie Policy
What is a cookie?
Cookies are small text files that are placed on your computer by websites that you visit. They are widely used in order to make websites work, or work more efficiently, as well as to provide information to the owners of the site.
How do cookies work?
A website’s cookies store information on your user device, which then gets sent back to that website each time you visit. Sometimes this information is essential to access a website’s functions – for example if you need to log in, a cookie will allow the website to recognise your log-in details.
Cookies can also be used to build a profile of your activity on a website – which pages you visit, how long you spend on each page. A website may then use this information to tailor the pages that you see when you visit the site in the future
How do we use cookies?
We use cookies for two purposes:
• To track you ‘session state’ so that when you interact with our website it is able to retrieve data that is specific to you. This allows you to login to our website, for example, where applicable.
• To create statistical data about how our visitors find and use our website. This allows us to improve the performance of the website. The information we collect is anonymous, it cannot be used to identify you personally.
A list of the cookies used by this website, and their purpose, is provided below:
| Google Analytics | Default Expiration | Description |
| __utma | 2 years from set/update | Used to distinguish users and sessions. The cookie is created when the javascript library executes and no existing __utma cookies exists. The cookie is updated every time data is sent to Google Analytics. |
| __utmt | 10 minutes | Used to throttle request rate. |
| __utmb | 30 mins from set/update | Used to determine new sessions/visits. The cookie is created when the javascript library executes and no existing __utmb cookies exists. The cookie is updated every time data is sent to Google Analytics. |
| __utmc | End of browser session | Not used in ga.js. Set for interoperability with urchin.js. Historically, this cookie operated in conjunction with the __utmb cookie to determine whether the user was in a new session/visit. |
| __utmz | 6 months from set/update | Stores the traffic source or campaign that explains how the user reached our site. The cookie is created when the javascript library executes and is updated every time data is sent to Google Analytics. |
| __utmv | 2 years from set/update | Used to store visitor-level custom variable data. This cookie is created when a developer uses the _setCustomVar method with a visitor level custom variable. This cookie was also used for the deprecated _setVar method. The cookie is updated every time data is sent to Google Analytics. |
| Google DoubleClick | Default Expiration | Description |
| 18 Months | Google DoubleClick Campaign Manager (DCM) is a third-party ad server that allows us to plan, execute and measure our display campaigns through DoubleClick by Google. It is where advertisers and agencies make ad placements, create floodlight tags and push to Google Tag Manager (GTM), and complete trafficking tasks. |
These cookies are used to store server-side, user-specific data in order to maintain a session state for the visitor, and to ‘remember’ their preferences. Our website uses this data to process user requests. Some functions of the website depend on these cookies and may not work properly, or at all, if they are disabled.
