Digital Marketing Cookie Notice

Last updated: 24 May 2018

This Cookie Notice explains how dunnhumby use cookies and similar technologies to recognise you when you visit our website https://www.dunnhumby.com. It explains what these technologies are and why we use them, as well as your rights to control our use of them. 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.

 

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.

The specific types of first and third party cookies served through our website and the purposes they perform 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 cookies?

You have the right to decide whether to accept or reject cookies. You can exercise your cookie preferences by clicking on the appropriate opt-out links provided in the cookie table above.

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. 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.

 

How often will you update this Cookie Notice?

We may update this Cookie Notice 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 Notice regularly to stay informed about our use of cookies and related technologies.

The date at the top of this Cookie Notice indicates when it was last updated.
