This Cookie Notice explains how dunnhumby uses cookies and similar technologies to recognise you when you visit our website https://www.dunnhumby.com. It provides more detail about the cookies and tracking technologies we use, why we use them, as well as your rights to control our use of them and should be read in conjunction with our Privacy Policy.
For details about how we use cookies in relation to our specific products please see the links to Cookie Notices at the login pages for those products.
What are cookies?
Cookies are small data files that are placed on your computer or mobile device when you visit a website. Cookies are widely used by website owners in order to make their websites work, or to work more efficiently, as well as to provide reporting information.
Cookies set by the website owner (in this case, dunnhumby) 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 advertising, 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.
There are different types of cookies than can be deployed on your device, and each serve a different purpose:
Necessary cookies: These Cookies are necessary for the website to function and cannot be switched off in our systems or our website will not work properly. They are usually only set in response to actions made by you during your visit to our website.
Analytics cookies: These Cookies allow us to collect information about how visitors interact with our website. We use this information to compile reports and to help measure and improve the performance of the website.
Advertising cookies: These Cookies may be set on our website by us or our advertising partners. They may be used to build a profile of your interests and show you relevant adverts on other sites. They do not store directly personal information but are based on uniquely identifying your browser and internet device.
Why do we use cookies?
We use first party and third party cookies for several reasons. Some 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 advertising, analytics and other purposes. This is described in more detail below.
In terms of how long we deploy the cookies for, there are session and persistent cookies. Session cookies only last as long as your online session and expire when you close the browser. The persistent cookies stay on your device after your browser has been closed. These cookies are used when we need to remember you for more than one browsing session, for instance to remember your preferences from one visit to the next.
The specific types of first and third party cookies served through our website and the purposes they perform and the duration they are deployed for, are described in the table below:

What about other tracking technologies, like web beacons or pixel tags?
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 “pixel tags” “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 or opened an e-mail that we have sent them. This allows us, for example, to monitor the traffic patterns of users from one page within our website to another, to deliver or communicate with cookies, to understand whether you have come to our website from an online advertisement displayed on a third-party website, to improve site performance, and to measure the success of e-mail marketing campaigns.
In many instances, these technologies are reliant on cookies to function properly, and so declining cookies will impair their functioning.
How can I control and delete cookies?
You have the right to decide whether to accept or reject cookies. You can exercise your cookie preferences by clicking on the available widget in our website at any time.
You can 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 your access to some functionality and areas of our website may be restricted.
