-<p>A few years ago the W3C (World Wide Web Consortium) created a mechanism for browsers to inform web servers that they would not like to be tracked.
- This is accomplished by including a <a href="https://en.wikipedia.org/wiki/Do_Not_Track">DNT (Do Not Track) header</a> with web requests.
- This header is enabled by default in Privacy Browser, although if desired it can be disabled in the settings.</p>
+ <body>
+ <h3><svg class="header"><use href="../shared_images/location_off.svg#icon"/></svg> Do Not Track</h3>
-<p>The DNT header doesn't really provide much privacy because most web servers ignore it. Yahoo programmed their servers to ignore the DNT header
- from Internet Explorer 10 when it was turned on by default because they argued that the user had not made the decision to enable DNT.
- Google and Microsoft ignore DNT even though they include a DNT feature in the browsers they distribute. Facebook also ignores DNT.</p>

-<h3>Advertisements</h3>
-<p>Privacy Browser Free includes a banner advertisement across the bottom of the screen that is populated by Google's
- AdMob network. By default, Google provides the <a href="https://support.google.com/googleplay/android-developer/answer/6048248?hl=en">advertising ID</a>
- of the device to the ads displayed through this network. This allows advertising companies to build a profile of
- the device that show which apps are installed (that display ads), how often they are used, and which ads the user is interested in.</p>
+ <h3><svg class="header"><use href="../shared_images/link_off.svg#icon"/></svg> URL Modification</h3>
-<p>Users can choose to disable the advertising ID in <strong>Settings</strong>, <strong>Google</strong>, <strong>Ads</strong>.</p>

-<p>The purpose of the free version of Privacy Browser is to allow people to test the features of the app. The standard version can be purchased
- on the major app stores or downloaded for free from
- <a href="https://f-droid.org/repository/browse/?fdfilter=privacy+browser&fdid=com.stoutner.privacybrowser.standard">F-Droid</a>.</p>

-<h3>Verizon Tracking Headers</h3>
-
-<p>Verizon, one of the major mobile carriers in the United States, adds a unique tracking header to all HTTP traffic on their network. The Electronic Frontier
- Foundation has written about the <a href="https://www.eff.org/deeplinks/2014/11/verizon-x-uidh">privacy implications of this practice</a>. Due to public pressure
- Verizon has created a way to <a href="http://www.clark.com/how-opt-out-verizons-super-cookie-tracking">opt out of this tracking</a>.</p>
-</body>
+ <p>Privacy Browser removes tracking ID sections of URLs, like <code>?utm_</code> from <a href="https://support.google.com/analytics/answer/1033867">Google Analytics</a> and
+ <code>?fbclick=</code> from <a href="https://fbclid.com/">Facebook</a>. URL modification can be turned off in the settings if it is causing issues.</p>
