Do Not Track or DNT is a web browser setting, that requests that a website or web application disable its tracking of the user. When DNT is enabled in your web browser, the web browser signals all websites that you visit, and the third-party services that they are using, that you do not want to be tracked. Here is an explanation of how DNT works, and how to turn it on in Google Chrome, Mozilla Firefox, Microsoft Edge, Opera, and Internet Explorer:
How does Do Not Track (DNT) work?
DNT is a setting in your web browser, that sends a header field to all websites and web apps that you use, with one of the following values:
- 1 – it states that the user does not want to be tracked
- 2 – it states that the user consents to be tracked
- Null – the value is for tracking has not been set by the user. The user has no preference on whether he or she should be tracked.
There is no standard for how web companies, websites, and web services interpret and use DNT. Some ad networks may refrain from tracking you for advertising purposes, and stop personalizing the ads they display in your web browser. Some websites may limit the information they collect about your browsing activity on their pages. For example, our website, when it encounters a DNT value of 1 coming from the browser of our visitors, collects a lot less information about that visit. A significant change is that we do not record the keywords that you used in Google search to reach one of our tutorials. When DNT is turned on, we know a lot less about how you reach our website, and how you use it. In contrast, other sites may ignore this web browser setting and do as they please.
The Do Not Track (DNT) setting has been available in all web browsers, starting in 2010. The first web browser to implement this feature was Mozilla Firefox, followed shortly by Internet Explorer, and other web browsers.

What is your reason for enabling Do Not Track (DNT)?
While enabling DNT may help in making your browsing history a bit more private, it does not mean that all websites, ad networks, and third-party services will stop tracking you. Some of them will ignore your DNT setting and track you the same as they track others. Before closing this tutorial, we would like to know your reason for turning on DNT and what your experience was after doing that.
