Last updated: 28th September 2022

Like many websites, (the Service) uses small files called cookies to help provide the best possible online experience for you.

Our Cookies Policy explains what cookies are, how we use cookies, how third parties we may partner with may use cookies on the Service, your choices regarding cookies and further information about cookies.

What are cookies?

Cookies are small pieces of text sent by your web browser by a website you visit. A cookie file is stored in your web browser and allows the Service or a third-party to recognize you and make your next visit easier and the Service more useful to you.

Cookies can be "persistent" or "session" cookies.

  • Persistent cookies continue to exist after you finish your website visit. They are eventually deleted, often after 6 months or longer. They are used to help the Service recognise when you return so that it can remember things like your preferences, or who you are.
  • Session cookies are deleted automatically soon after you finish your website visit, usually within 30 minutes. They are used to help the Service to remember the status of your current visit, for example, a session ID might be stored to ensure you remain logged in.

You can remove cookies from your device at any time, and your device will automatically delete expired cookies.

Types of cookies

Cookies can be set in two ways – some are set by the Service itself. Others are set by other services which may be used bring enhanced functionality.

First-party cookies These cookies are set directly by the Service. Only the Service can read them.
Third-party cookies These cookies are set by other digital services and are accessible only by those digital services. For example, if a webpage contains an embedded YouTube video, YouTube may set its own cookies to enable the video to work correctly. Some cookies are set by services used to provide a better experience for you. For example, Google Analytics is a common service used to understand how users interact with websites so the website owners can make improvements, so the website is easier to use. Some cookies are set by services for advertising purposes. For example, and advertising platform may set a cookie so that it recognises a user across different websites. It is not the Service which sets these third-party cookies.


We categorise cookies based on how they are used and help you to make broad choices about which cookies you allow us to set.
