You can change your cookie settings for the bt.com website through the Manage Cookie Settings page at any time.

Cookies and similar technologies (“cookies”) allow small pieces of information to be read from and/or placed onto your device when you visit a website or application. This allows for websites and applications to recognise you or your device on each subsequent visit so that they can remember things like preferences, log in information and saved shopping carts.

Cookies are very useful and do lots of different jobs. For example, they enable you to move between our web pages efficiently, remember your preferences when you visit us again and generally improve your experience when browsing with us. They can also help to ensure that adverts you see online are more relevant to you and your interests, which in turn help us to tailor our communications.

Cookies last for different lengths of time depending on the job they do. There are session cookies and persistent cookies:

• Session cookies only last for your online session and disappear from your device when you close your browser.
• Persistent cookies stay on your device after the browser has been closed and last for the period of time specified in the cookie.

You can find information about how BT processes your personal data in our privacy policy which can be found at bt.com/privacy-policy

The core purpose of marketing cookies (otherwise known as advertising cookies) is to provide BT with valuable insights into what our customers want, including but not limited to, insight into the communications and services our customers and potential customers may be interested in.

Disabling marketing cookies, generally does not stop you receiving advertising. It simply means that the advertising you receive is less likely to be aligned with your interests.

In order to gain the insights, in some instances we may analyse your personal information to create a profile of your interests and preferences so that we can contact you with information relevant to you. This helps to avoid you receiving advertising that is not relevant to you or your interests.

In some instances, we may also use this information to inform us of how well our communications are received by our customers and website users. In order to do this, we may make use of additional information about you when it is available from internal and external sources to help us do this effectively.

These cookies are also linked to services provided to BT and our customers by our trusted partners (see the Third Parties section below for more information). We/our trusted partners may also share data derived from these cookies with other members of the BT Group for the purpose and provision of the services they provide.

We use marketing cookies to:

• Link to social networks who may use information about your visit to target advertising to you on other websites;
• Provide advertising agencies, our trusted partners and other members of the BT Group with information on your visit so that we can present adverts that you may be interested in, and prevent you receiving duplicate ads – see the “Online behavioural advertising” section below for further details;
