Like most organisations, Wellcome uses cookies to capture information about our websites’ users. A cookie is a small file of letters and numbers that we save to your computer or device if you agree.

Cookies allow us to recognise and count your visits, and to see how you move around our sites while you are using them. This helps us to provide you with a good experience while you browse and to improve the way our sites work, for example by making sure you can find what you need.

Third-party cookies

As well as the cookies we set, we may use third party cookies and other similar technologies set by other websites when you visit them to help us to understand some simple information about the age, location and interests of the people who visit our sites. Third parties may use these technologies to collect or recieve information from our website and elsewhere on the internet and use that information to provide measurement services and to target adverts.

We only ever use this information in aggregate, and never associate it with any personal information that might identify you.

Cookies we use on our sites by type

Across our sites we may make use of Flash files, which present information, allow integration with third parties (such as YouTube) and can offer a richer online experience. We have strived to identify any Flash elements that are likely to set cookies but, at this point in time, we cannot guarantee the status of every Flash file. Adobe offers a tool to monitor and remove Flash cookies.

We use Google Analytics, Google Analytics demographics and interest reporting, and integrated services that require Google Analytics to collect data via advertising cookies and identifiers. Google Analytics is a tool that helps website and app owners to understand how their visitors behave. It uses a set of cookies to collect information and report website usage statistics without personally identifying individual visitors to Google. It also uses some cookies set by other websites to help us understand more about our sites’ visitors.

We use web beacons like Facebook Pixel to understand what users of our site do after clicking a link in an email that we’ve sent to a list of subscribers, or clicking on an advert we’ve placed on Facebook. This information helps us to improve the content we make, reach people who are interested in our work with our advertising and social activity, and measure how effective our advertising and newsletters are, without personally identifying individual site visitors, newsletter subscribers or Facebook users.

The following table is a list of the cookies we use, why we use them, and on which of our sites.
