Our website at worldfirst.com, owned and maintained by WorldFirst (“this Website”) uses cookies and similar technologies (such as pixels, beacons and tags, together as “cookies”) to distinguish you from other users of this Website. This helps us to provide you with a good experience when you browse this Website and also allows us to improve our Website.
While WorldFirst tries to keep the information in this Cookies Policy up-to-date, please note that the information in the Cookies Policy represents a snapshot in time, last updated and accurate as at the date stated above. Due the constant innovation of our Website, the non-static character of the Internet and the third parties involved in the use of cookies, it is possible that not all cookies and information are set out in this Cookies Policy.
To the extent that we collect personal data with the help of cookies, we will process it in accordance with our Website Privacy Policy.
What are cookies?
Cookies are small data files that a website automatically downloads to a user’s device when they visit a website. They are primarily used in helping the website recognise a user that has visited the website previously (such as remembering a user’s login, preferred language, font size and other display preferences). They can also store account and password information so a user doesn’t have to keep re-entering the information when they revisit the website or browse from one page to another.
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 on a user’s device.
Cookies used on this Website
We use four categories of cookies on our Website:
- Strictly necessary cookies. These are cookies that are required for the operation of this Website. They include, for example, cookies that enable you to log into secure areas of our Website.
- Analytics or performance cookies. These allow us to recognise and count the number of visitors and to see how visitors interact with this Website when they are using it. This helps us to improve the way this Website works, for example, by ensuring that users are finding what they are looking for easily.
- Functionality cookies. These cookies recognise your device when you return to this Website. They enable us to personalise our content for you and remember your preferences for example greetings, choice of language, region and login details.
- Marketing cookies. These cookies record your visit to this Website, the pages you have visited and the links you have followed. We will use this information to make our Website and the advertising displayed on it more relevant to your interests. We may also share this information with third parties for this purpose.
Depending on how long the cookies remain in your browser, they may also be divided into two different groups:
- Session cookies. These are temporary cookies that remain in the cookie file of your browser until you leave this Website.
- Persistent cookies. These remain in the cookie file of your browser even after you close the browser. They have expiration dates and can be used to store information that can be accessed across multiple browsing sessions.
