- <h3>Do Not Track</h3>
+ <meta charset="UTF-8">
- <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.</p>
+ <link rel="stylesheet" href="../css/theme.css">
- <p>The DNT header doesn't really provide much privacy because most web servers ignore it. For example, Yahoo, Google, Microsoft, and Facebook all ignore at least some DNT headers.</p>
+ <!-- Setting the color scheme instructs the WebView to respect `prefers-color-scheme` @media CSS. -->
+ <meta name="color-scheme" content="light dark">

+ <h3><svg class="header"><use href="../shared_images/location_off.svg#icon"/></svg> Do Not Track</h3>
- <h3>Advertisements</h3>
+ <p>Alcuni anni fa il W3C (World Wide Web Consortium) ha creato per i browser un meccanismo per informare i web server che preferiscono non essere tracciati.
+ Questo è ottenuto attraverso l'inclusione nella richiesta al server di un header denominato: <a href="https://en.wikipedia.org/wiki/Do_Not_Track">DNT (Do Not Track)</a>.</p>
- <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>
+ <p>L'header DNT in realtà non garantisce nessuna privacy dal momento che la maggior parte dei web server lo ignora, come ad esempio Yahoo, Google, Microsoft e Facebook,
+ che ignorano tutti almeno alcuni degli header DNT. A partire dalla versione 3.8 in Privacy Browser non è più presente l'opzione per inviare intestazioni DNT.</p>
- <p>Users can choose to disable the advertising ID in <strong>Settings</strong>, <strong>Google</strong>, <strong>Ads</strong>.</p>
- <img class="center" src="../en/images/advertising_id.png" height="640" width="360">
+ <h3><svg class="header"><use href="../shared_images/link_off.svg#icon"/></svg> Modifica delle URL</h3>
- <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>
+ <p>Privacy Browser removes tracking IDs and AMP (<a href="https://en.wikipedia.org/wiki/Accelerated_Mobile_Pages">Accelerated Mobile Pages</a>) redirects from URL queries.
+ There is a blog post that is updated with the <a href="https://www.stoutner.com/url-modification/">current list</a> of modifications.
+ URL modification can be turned off in the settings if it is causing issues.</p>
- <h3>Verizon Tracking Headers</h3>
+ <h3><svg class="header"><use href="../shared_images/disabled_by_default.svg#icon"/></svg> X-Requested-With Header</h3>
- <p>Verizon, one of the major mobile carriers in the United States, adds a unique tracking header to all unencrypted 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>
+ <p>Google programmed Android’s WebView to send an X-Requested-With header with every request.
+ The value of the X-Requested-With header is set to the application ID, which in the case of Privacy Browser is <code>com.stoutner.privacybrowser.standard</code>.
+ Currently, it isn't possible to remove this header, but the value can be changed. By default, Privacy Browser sends a null (empty) value for the X-Requested-With header.
+ Even though the spec allows for null header values, some web servers don't like them, so Privacy Browser has the option to revert to the default behavior of sending the app ID.
+ Because this setting is cached when a URL is first loaded, and isn't changed when reloading a page or navigating history,
+ changes to this setting may not be applied until Privacy Browser is restarted.
+ There is a <a href="https://www.stoutner.com/the-x-requested-with-header/">blog post</a> with additional information.
+ The X-Requested-With header will be <a href="https://redmine.stoutner.com/issues/37">completely removed</a> in the 4.x series with the release of Privacy WebView.</p>
