By sharing your personal data with us, you’re enabling us to use our resources in the most effective way possible, and ensure your journey with us as a supporter is the best it can be.

We keep this policy under review and it will be updated from time to time. 

Who we are

We, Leuka, are a small, specialist cancer charity. We fund research in order to create a better future for leukaemia and blood cancer patients; we aim to turn this research into new and improved treatments as quickly as possible, so that patients can live better, longer lives.

By using our website, interacting with our social media accounts, or providing us with your data, you are consenting to this privacy policy and the ways in which we use your information. If you do not agree with this policy then please do not provide us with your information or continue using our sites and social media accounts.

  • To provide you with the services or information you have asked for
  • To process your donation or support your fundraising, including processing Gift Aid
  • To comply with applicable laws and regulations, such as HMRC guidelines for processing Gift Aid
  • For Leuka’s internal administrative purposes, including to administer any funding applications received
  • To provide you with information about us and our events, products or services that we provide or provide access to
  • To ensure that content from our site is presented in the most effective manner for you and for your computer.

How we collect this information about you 

Information you give us

We may directly collect information from you in the following ways:

  • Via forms on our website
  • Through website cookies
  • By email or phone
  • At in-person events

Information we receive from other sources

We may indirectly collect information from you in the following ways:

  • When you give your permission to independent event organisers, such as Run Britain, the London Marathon or online fundraising sites like JustGiving, to release your details to us. There will be a clear opt-in on these external sites, which will allow them to pass your details on to us. These external sites will also have their own privacy policies you may want to read
  • We also want to not only meet, but deepen our connection with, individuals and organisations who share our passion. We are committed to nurturing collaborative relationships with donors, prospective donors and others so we can do more for those who suffer with leukaemia. To enable us to find and connect with people who share our passion and ability to support us, we may also use the information you provide to us in combination with publicly available information.

How we use your information for marketing purposes

Depending on the consent you have given us, we will use your data to send you updates via email phone, post, and/or social media. 

We aim to use your data to contact you about information that is relevant to your interests. For example, an interested runner may receive different communications than a volunteer who is not interested in running events. 

Whatever the topic, it will always be with your consent. 

How we use your information

Whilst generally we will seek consent at the point of collecting your data, in some cases we may process data without consent but only when we are legally allowed to do so, and where it is in our legitimate interests. We will always respect your rights in these matters. 

You always have control over how you would like to hear from us. If at any time you do not wish to receive further information about us and our services, or you wish to change your contact details or preferences, please do contact us at You can also write to us at 52 Portland Place, London, W1B 1NH, or call the office on 020 7299 0722. 

If you request to receive no further contact from us, we need to keep some basic information in order to avoid sending you unwanted materials in the future, and to ensure that we do not accidentally store details for the same person multiple times.

How long we keep your data for

We will only keep your information for as long as we need it in order to provide you with the services or information you have required, to administer your relationship with us, to comply with the law, or to ensure we do not communicate with people that have asked us not to. When we no longer need this information we will dispose of it securely. 

Where we store your personal data

All information you provide to us is stored on our secure servers in the UK. Most payment transactions are completed using secure online methods. On a rare occasion when you directly provide us with the payment details we delete the details immediately after processing.

Unfortunately, the transmission of information via the internet is not completely secure. Although we will do our best to protect your personal data, we cannot guarantee the security of your data transmitted to our site; any transmission is at your own risk. Once we have received your information, we will use strict procedures and security features to try to prevent unauthorised access.

Who has access to your information

We may allow our staff, consultants or other external providers acting on our behalf to access and use your information for the purposes for which you have provided it to us. We only work with suppliers we trust and they are only allowed to use the data to process on our behalf and never for their own purposes. 

We will only share your sensitive information with third parties where it is directly relevant to the services you have requested. We make sure that your data is treated with the same level of care as if we were handling it directly.

We may disclose your personal information to third parties if we are under a duty to disclose or share your personal data in order to comply with any legal obligation, or in order to enforce or apply any agreements, or to protect the rights, property or safety of Leuka, or others.

Cookie Policy

Leuka, 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 the above 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. Leuka) to directly identify users and their accounts.


When we email you we may use a tracking pixel in the links of the email you receive. As before, this does not collect directly identifying information from you, but 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.
