Leukaemia UK, like most websites, uses cookies to ensure your experience of using our website is the best it can be. Please note that if you decide to delete or refuse to accept cookies, this may affect the functionality of some aspects of the website.

What are cookies?

Cookies are text files containing small amounts of information that are downloaded to your computer or mobile device when you visit a website or use a mobile application. They provide information to the owners of the website so they can ensure it works well and provides you with the information you need.

Here are the most common types of cookies:

Session cookies – these are temporary files, which are erased when you close your browser. When you restart your browser and go back to the site that created the cookie, the website will not recognise you. Each time you return to a website with session cookies, a new one will be generated, which will store your browsing information and will be active until you leave the site and close your browser.

Persistent cookies – these files stay in one of your browser's subfolders until you delete them manually or your browser deletes them based on the duration period contained within the persistent cookie's file.

First Party Cookies – these are cookies that are served directly by a website to your computer. They are most often used to recognise your computer when it revisits that site and to remember your preferences as you browse.

Third-party cookies – these are most generally used for advertising. By adding tags to a page, advertisers can track a user or their device across different websites. That helps build a profile of the user based on their habits, so messages can be better targeted to their interests.

We use First Party and Third-Party cookies on our site.

How we use cookies                

We use cookies to improve your experience of our website, and to better understand how our site is used. Cookies may tell us, for example, whether you have visited our site before or whether you are a new visitor. This data is anonymised and does not provide us with directly identifying information such as your name or address, and we do not associate your IP address with any personal data you may have provided to us in another way (e.g. by fundraising for us).

Instead, we use the information provided to build a profile of our visitors and understand how visitors move around our site. We may also transfer this information to third parties where required to do so by law, or where such third parties process the information on our behalf. For more information about our data processing, please read our Privacy Policy.

You may refuse the use of cookies by selecting the appropriate settings on your browser. If you do, you may not be able to use the website as it is intended by its design.

Google Analytics

We use Google Analytics to help us understand how our visitors use this website, which helps us to ensure we are meeting your needs and to make improvements.

Google Analytics uses cookies to collect information about how visitors use our site. These cookies do not collect any information that can identify you personally. You can find more information about Google Analytics, including their privacy policy and how to opt out of Google Analytics cookies here.

Facebook Pixel

We use the Facebook Pixel, a tracking tool that identifies actions taken on our website and attributes those actions to Facebook Users. A user’s data beyond those actions is not saved or shared, and data collected via the Facebook Pixel does not allow advertisers (i.e. Leukaemia UK) to directly identify users and their accounts. You are able to opt out of Facebook Pixel by amending the settings on your Facebook account.


When we email you, we may use a tracking pixel in the links of the email you receive. This collects information from you and lets us know how many people in total have opened or clicked through to a link on our website from the email. This enables us to understand what topics our supporters are most interested in hearing about.

Your consent

By using our website, you consent to our use of cookies as updated from time to time and the cookies we use will be stored on your device (unless rejected or disabled by your browser, or manually cleared by yourself).

Changing your browser settings

Internet browsers normally accept cookies by default. However, it is possible to set an internet browser to reject cookies. If you do not accept our use of cookies as set out in this Policy, please set your internet browser to reject cookies. Note that this may impair your ability to use our website.

To change your browser’s cookie settings, click the ‘Help’ menu in your browser toolbar. Here is a guide to changing cookie settings in either Internet Explorer, Chrome, Firefox or Safari.

Except for essential cookies, all cookies will expire after 2 years. Find out more about cookie expiration.
