Cookie Policy
This website (www.ukbiobank.ac.uk, referred to as the “website” or “site” in this cookies policy) is run by UK Biobank Limited (collectively referred to as "Biobank", "we", "us" or "our" in this cookies policy).
Our website uses cookies to distinguish you from other users of our website. This helps us to provide you with a good experience when you browse our website and also allows us to improve our site.
What are cookies?
A cookie is a small file of letters and numbers that we store on your browser or the hard drive of your computer. Cookies contain information that is transferred to your computer's hard drive.
Cookies set by the website owner (in this case, by us) are called 'first party cookies'. Cookies set by parties other than the website owner are called 'third party cookies'. Third party cookies enable third party features or functionality to be provided on or through the website (e.g. like interactive content and analytics). The parties that set these third party cookies can recognise your computer both when it visits the website in question and also when it visits certain other websites.
Cookies may be either “persistent” cookies or “session” cookies: a persistent cookie will be stored by a web browser and will remain valid until its set expiry date, unless deleted by the user before the expiry date; a session cookie, on the other hand, will expire at the end of the user session, when the web browser is closed.
We use both session and persistent cookies on our website. You can block cookies by activating the setting on your browser that allows you to refuse the setting of all or some cookies. However, if you use your browser settings to block all cookies (including essential cookies) you may not be able to access all or parts of our site.
Why do we use cookies?
We use first party and third party cookies for several reasons. Some cookies are required for technical reasons in order for our website to operate, and we refer to these as 'essential' or 'strictly necessary' cookies. Other cookies enable us to track and target the interests of our users to enhance the experience on our website. Third parties serve cookies through our website for analytics and other purposes. We use the following cookies:
- Strictly necessary cookies.These are cookies that are required for the operation of our website and to use some of its features. They include, for example, session cookies that ensure normal navigation of the website.
- Analytical or performance cookies.These allow us to recognise and count the number of visitors and to see how visitors move around our website when they are using it. This helps us to improve the way our website works, for example, by ensuring that users are finding what they are looking for easily.
- Functionality cookies.These are used to recognise you when you return to our website. This enables us to personalise our content for you, greet you by name and remember your preferences (for example, your choice of language or region).
- Social networking cookies.These cookies are used to enable you share pages and content that you find interesting on our website through third party social networking and other websites. These cookies may also be used for advertising purposes too.

How can I control cookies?
You have the right to decide whether or not accept or reject non-essential cookies. You can change your cookie preferences at any time by clicking on the the cookie control icon on the bottom left corner of any page on this website. You can then adjust the available sliders to "On" or "Off". You may need to refresh your page for your settings to take effect.
Alternatively, you can also exercise your cookie preferences by clicking on the appropriate opt-out links provided in the cookie table above.
You can also set or amend your web browser controls to accept or refuse cookies. If you choose to reject cookies, you may still use our website, though some functionality of the website and your access to some areas of our website may be restricted. As the means by which you can refuse cookies through your web browser controls vary from browser-to-browser, you should visit your browser's help menu for more information.
What about other tracking technologies, like web beacons?
Cookies are not the only way to recognise or track visitors to a website. We may use other, similar technologies from time to time, like web beacons (sometimes called 'tracking pixels' or 'clear gifs'). These are tiny graphics files that contain a unique identifier that enable us to recognise when someone has visited our website. This allows us, for example, to deliver video content embedded on our website and to facilitate sharing of our news pages to social media. In many instances, these technologies are reliant on cookies to function properly, and so declining cookies will impair their functioning.
How often will you update this Cookie Policy?
We may update this cookie policy from time to time in order to reflect, for example, changes to the cookies we use or for other operational, legal or regulatory reasons. Please therefore re-visit this cookie policy regularly to stay informed about our use of cookies and related technologies.
The date at the top of this cookie policy indicates when it was last updated.
Where can I get further information?
If you have any questions about our use of cookies or other technologies, please email us at dpo@ukbiobank.ac.uk.
