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 advertising ID - 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.
+ +Users can choose to disable the advertising ID in Settings, Google, Ads.
+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 DNT (Do Not Track) header with web requests.
-
+ The DNT header doesn't really provide any privacy because most web servers ignore it. For example, Yahoo, Google, Microsoft, and Facebook all ignore at least some DNT headers. + Beginning with version 3.8, Privacy Browser no longer has the option to send a DNT header.
-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 - F-Droid.
+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 privacy implications of this practice. Due to public pressure - Verizon has created a way to opt out of this tracking.
- - +Privacy Browser removes tracking ID sections of URLs, like ?utm_ from Google Analytics and
+ ?fbclick= from Facebook. URL modification can be turned off in the settings if it is causing issues.
