Cookie Policy

Last updated: March 2025

You can manage your cookie preferences at any time

A cookie is a small file of letters and numbers downloaded onto a device when the user accesses certain websites. A cookie will allow a website to recognise a user's device.

A cookie will contain the name of internet location (the domain) from which the cookie has come and the lifetime of the cookie (a cookie will usually expire after a certain period of time).

Cookies cannot be used to carry viruses, or install malware.

What types of cookie are there and which ones does WorldFirst use?

Two types of cookies are used on this website:

Session cookies, which are temporary cookies that remain in the cookie file of your browser until you leave the site and;
Persistent cookies, which remain in the cookie file of your browser for much longer (though how long will depend on the lifetime of the specific cookie).

We use four categories of cookie on our website:

Strictly necessary cookies

These cookies are essential in order to use a website and its features. They ensure security and privacy when accessing secure sites. They do not gather information about you that could be used for marketing or tracking where you have been on the internet.

If you choose to block these cookies you may experience reduced functionality and not be able to access all or parts of our website.

Analytics or performance cookies

These cookies collect data on how visitors interact with the website, including, but not limited to the number of visitors, pages or links accessed and length of time spent on the website or specific page. This statistical data is then used to improve the user experience.

Functionality and profile cookies

These cookies recognise your device when you return to a website. They enable personalised greetings, content and preferences as well as being able to remember login details.

Marketing cookies

These cookies gather information about your browsing habits by remembering your device has visited a website and sharing that information with other organisations such as advertisers or platforms on which a company advertises. They do this to provide you with online advertisements that are targeted to your browsing history and therefore more relevant to you and your interests.
