Do Not Track (DNT) is a step toward putting you in control of the way your information is collected and used online. Do Not Track (DNT) is a feature in your web browser (e.g. Internet Explorer, Firefox, Chrome, etc.) that allows you to let a website know you would like to opt-out of third-party tracking for purposes including behavioral advertising. It does this by transmitting a Do Not Track (DNT) HTTP header every time your data is requested from the Web.
Do Not Track (DNT) may interfere with some personalized services you enjoy. For example, a Do Not Track (DNT) request might mean you would have to type in your zip code each time you want to view a weather report, rather than seeing the weather automatically displayed. Personalization on websites can save you time and repetitive typing, but it requires data.
