Do Not Track或DNT是一种网络浏览器功能，可让网站知道您不想被跟踪。当您在网络浏览器中启用DNT设置时，它会向您访问的所有网站和他们正在使用的第三方服务发送一个包含您的浏览流量的“不跟踪”(Do Not Track)请求，要求他们不要收集有关您和您的浏览的数据习惯。本指南解释了DNT的工作原理，并展示了如何在(DNT)Google Chrome、Mozilla Firefox、Microsoft Edge和 Opera中开始发送Do Not Track请求：
什么是不跟踪请求？
Do Not Track请求是您的浏览器向您访问的网站发送的信号，告诉他们您不想要他们的cookie(cookies)并要求禁用用户跟踪。虽然您可以在任何浏览器上启用DNT以发送此请求，但对于网络公司、网站和网络服务如何解释和使用DNT没有标准。如果您访问的网站设置为尊重您浏览器的“不跟踪”(Do Not Track)设置，则广告网络应避免出于广告目的跟踪您，并停止个性化它们在您的网络浏览器中显示的广告。此外(Furthermore)，网站应限制他们收集的有关您在其页面上的浏览活动的信息。
当我们的网站收到来自访问者浏览器的“请勿跟踪(Do Not Track)”请求时，它收集的有关该访问的信息会减少。另一个重大变化是我们不会记录您在Google 搜索(Google Search)中使用的关键字来访问我们的指南。简而言之，当DNT开启时，我们对您如何访问和使用我们的网站知之甚少。
如果您不确定浏览器当前的“不跟踪”(Do Not Track)设置，请访问All About DNT以确定您是否被跟踪。

How to enable Do Not Track in Chrome, Firefox, Edge, and Opera
Do Not Track or DNT is a web browser feature that lets websites know you don’t want to be tracked. When you enable the DNT setting in your web browser, it sends a Do Not Track request with your browsing traffic to all the websites you visit and the third-party services they’re using, asking them not to collect data about you and your browsing habits. This guide explains how DNT works and shows how to start sending Do Not Track requests in Google Chrome, Mozilla Firefox, Microsoft Edge, and Opera:
What is a Do Not Track request?
A Do Not Track request is a signal sent by your browser to the websites you visit, telling them that you don’t want their cookies and asking to disable user tracking. While you can enable DNT on any browser to send this request, there is no standard for how web companies, websites, and web services interpret and use DNT. If the websites you visit are set to respect your browser’s Do Not Track setting, ad networks should refrain from tracking you for advertising purposes and stop personalizing the ads they display in your web browser. Furthermore, websites should limit the information they collect about your browsing activity on their pages.
When our website receives Do Not Track requests from our visitors’ browsers, it collects less information about that visit. Another significant change is that we do not record the keywords you used in Google Search to reach one of our guides. In a nutshell, when DNT is turned on, we know less about how you reach and use our website.
If you’re not sure about your browser’s current Do Not Track setting, visit All About DNT to determine whether or not you’re being tracked.
