Cookies

We and our partners use cookies and similar technologies, such as tags and pixels (or "cookies"), to personalise and improve your customer experience as you use our websites and mobile apps and to provide you with relevant online advertising. This section contains more information about cookies, including how we use them and how you can control how we use them.

How we use cookies

Cookies are small text files containing a unique identifier that are stored on your computer or mobile device so that your device can be recognised when you're using a particular website or mobile app. Some cookies may only be used during your visit, while others may be used to track how you interact with services and content over time.

Cookies help us provide important features and functionality on our websites and mobile apps and improve your experience. Cookies can also be used to help us detect fraudulent activity or prevent security breaches, so we may record information about your device within the cookie. The reasons we use cookies are as follows:

• Improve the way our websites and mobile app work
  

  Cookies allow us to improve the way our websites and mobile apps work, so that we can personalise your experience and allow you to use many of their useful features. For example, we use cookies so we can remember your preferences and the contents of your shopping basket when you return to our websites and mobile app.

• Improve the performance of our websites and mobile app
  

  Cookies can help us to understand how our websites and mobile app are being used. For example, by telling us if you get an error message as you browse. These cookies collect data that is mostly aggregated and anonymous.

• Deliver relevant online advertising, including via social media

We use cookies to help us deliver online advertising that we believe is most relevant to you on our websites and other organisations' websites, and using social media.

Cookies used for this purpose are often placed on our websites by companies providing specialist services to us. These cookies may collect information about your online behaviour, such as your IP address, the website you arrived from, and information about your purchase history or the content of your shopping basket. This means that you may see our adverts on our websites and on other organisations' websites. You may also see adverts for other organisations on our websites.

To help us to deliver online advertising that's relevant to you, we may also combine data we collect through cookies placed on our website or on your device with other data that we’ve collected. For example, information about your use of Clubcard and in-store purchases.

• Measuring the effectiveness of our marketing communications, including online advertising

Cookies can tell us if you've seen a specific advert, and how long it's been since you've seen it. This information allows us to measure the effectiveness of our online advertising campaigns (and those of our retail partners) and control the number of times you're shown an advert. We also use cookies to measure the effectiveness of our marketing communications. For example, when you purchase a product from us online we can see if you saw an advert for that product elsewhere.

Third parties

We may also use personal data from other sources, such as specialist companies, media partners, retail partners and public registers (such as the electoral register).

When we work with specialist companies that provide us with personal data about you, they'll have told you about this data sharing at the time it was collected. We use this and our own data to better understand our customers.

We also use this personal data to make sure we have up-to-date details about you. We don't give personal data we’ve collected or created from you back to these companies.
