This Cookie Notice explains how dunnhumby use cookies and similar technologies to recognise you when you visit our website https://shopperthoughts.com . It explains what these technologies are and why we use them, as well as your rights to control our use of them.
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 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 when it visits certain other websites.
Why do we use cookies?
We use first party and third-party cookies for several reasons. Some cookies are required for technical reasons for our website to operate, and we refer to these as "essential" or "strictly necessary" cookies. Other cookies also 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:

How to Refuse |

Essential These cookies are essential to the operation of the website. They include, for example, cookies that enable users to log into secure areas of a website. |
|
Because these cookies are strictly necessary to deliver the website to you, you cannot refuse them. Doing so would mean you cannot interact with the website. |
|
Functional These are used to recognise users when they return to a website. They enable the personalisation of content, the recognition of users and remember user preferences (for example, their choice of language or region). |
|
To refuse these cookies, please follow the instructions below under the heading "How can I control cookies?" |
|
Performance/Analytical These types of cookies allow providers to recognise and count the number of visitors and to see how visitors move around their website when they are using it. This assists providers in improving the way their website works, for example, by ensuring that users are finding what they are looking for easily. |

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.
