Version 2026-10-09
Last updated: 9 October 2026
Our website, horse trading platform ("Platform"), and newsletters and other email and social media marketing campaigns use cookies and other technologies to distinguish you from other users of our website and Platform. This helps us to provide you with a good experience when you browse our website and Platform and also allows us to improve our site and Platform.
Cookies and tracking technologies
A cookie is a small file of letters and numbers that we store on your browser or the hard drive of your computer where this is necessary to operate or our website or Platform, or if you agree. Cookies contain information that is transferred to your computer's hard drive.
Where you subscribe to our newsletters or marketing communications, we may use email tracking technologies to understand how recipients interact with our emails. These may include tracking pixels, which are small invisible image files that load when an email is opened, and tracked links, which record when a recipient clicks a link in an email. We use this information to measure engagement, improve our communications and tailor future marketing. You can unsubscribe from marketing emails at any time using the unsubscribe link in the email or by changing your preferences in your account.
Why we use cookies and other technologies
Like most organisations with online presence, we use cookies and similar technologies to:
- provide our services including our website and Platform which is not possible without certain essential cookies;
- remember your settings and preferences to improve your experience, speed up your searches and recognise you when you return to our service;
- understand our online traffic through analytics tools;
- personalise Platform accounts and provide saved preferences and listing data for product functionality purposes;
- personalise our marketing and advertising by creating an advertising profile; and
- connect you with our social media features.
To accomplish this, we will, in certain cases, also link information from cookies and similar technologies with personal data held about you.
The cookies we use
We use the following cookies and other technologies:
- Essential. These are cookies that are required for the operation of our website and Platform. These essential cookies are always enabled because our website and Platform won’t work properly without them. They include, for example, cookies that enable you to log into secure areas of our website and Platform or complete transactions via our Platform. You can switch off these cookies in your browser settings but you may then not be able to access all or parts of our website.
- Analytical cookies. These allow us to recognise and count the number of visitors and to see how visitors move around our website and Platform when they are using it. This helps us to improve the way our website works, for example, by ensuring that users are finding what they are looking for easily.
- Targeting cookies. These cookies record your visit to our website and Platform, the pages you have visited and the links you have followed. We will use this information to make our website and Platform and the advertising displayed on it more relevant to your interests. We may also share this information with third parties for this purpose so that they can serve you with relevant advertising on their websites. Targeting cookies load only when you allow the marketing category
We will deploy cookies and similar technologies ourselves (first party cookies). However, our services may also include cookies and similar technologies deployed by third parties (third party cookies). These named third parties may include, for example, advertising networks and providers of external services like web traffic analysis services. These third party cookies are likely to be analytical cookies or performance cookies or targeting cookies.
Our cookies and similar technologies are listed in the table below.
