Stealth Mode

Many websites gather information about their visitors, such as their IP addresses, information about the browser and operating system installed, screen resolution, and even what page the user was redirected from. Some web pages use cookies to mark the browser and save your personal settings, user preferences, or “recognize” you upon your next visit. Stealth Mode safeguards your personal information from such data and statistics gathering systems.

You can flexibly adjust the work of Stealth Mode: for instance, you can prohibit the website to receive the search request you used to find it on the Internet, automatically delete both third-party and website’s own cookies, turn off browser geolocation sharing that can be used to track your whereabouts, hide your real IP-address or even indicate one of your choice.

Enable Stealth Mode

Turn the Stealth Mode module on or off.

Hide your search queries

When you proceed to the website from Google, Yahoo or any other search engine, this option hides the search query you used to find it.

Send Do-Not-Track header

Sends a Do-Not-Track (DNT) HTTP header to queried websites that requires web apps to disable tracking of your activity.

Remove X-Client-Data header from HTTP requests

Forbids Google Chrome to send its version and modifications information with requests to Google domains (including Double Click and Google Analytics).

Self-destructing third-party cookies

Websites store your information and preferences with cookies – e.g., they remember the language you chose, the location or even the list of goods in your cart. When you get back to the site, your browser sends back the cookies belonging to that website, which allows it to “recall” your data.

Third-party cookies are those implemented by a website that is different from the one you are browsing at the moment. E.g., cnn.com may have a Facebook “Like” widget on it page. This widget will implement a cookie that may be read by Facebook later on. Some advertisers use such cookies to track what other sites you visit where their ads are posted.

Put a time period (in minutes) by the end of which all third-party cookies will be destroyed. Set the timer to 0 in order to block them completely.

Self-destructing first-party cookies

We do not recommend enabling this option as it may severely interfere with the work of certain sites.
Put a time period (in minutes) by the end of which all cookies will be destroyed. Set the timer to 0 in order to block them completely.

Disable cache for third-party requests

When the browser addresses a page, the server assigns it an ETag, which the browser then uses to cache the contents. Upon subsequent requests it sends the ETag to the corresponding server, thus letting it learn the visitor’s identity. While the site files are cached, the ETag is sent every time your browser addresses this site. If the site has content embedded from another server (e.g., an image or iframe), that server will also be able to track your activities without your knowing it.

Block WebRTC

WebRTC (Real Time Communications) is a technology that allows streaming of data directly between browsers and apps. It can let others know your real IP address even if you use a proxy or VPN.
Enabling this option can disrupt the work of certain browser applications, such as messengers, chats, cinemas, or games.

Block Push API

Push API enables servers to send messages to web applications regardless of browser status. This means you may see notifications from varous websites even if your browser is hidden to tray or not launched. Enable this option to block browser Push API completely.

Block Location API

Enabling this option will prohibit the browser from sending GPS data that could be used to find your location and modify your search results or otherwise influence your web experience.

Hide Referer from third-paries

Referer is one of HTTP headers for browser-to-server request. It contains the URL of request source. If you advance from one page to another, Referer will save the URL of the initial page. The server is often equipped with software that analyzes Referer and extracts various information from it. Enabling this option hides the current website from third-party sites by changing the HTTP header.
You can also set Referer of your choice by typing it into the Setup Referer field. Leave the field empty to use the default Referer.

Hide your User-Agent

When you visit a website, your browser send the server its information. It looks like a text line that is a part of HTTP request beginning with “User-Agent:”. It usually includes the name and version of the browser, operating system, and language settings. We always replace your operating system with Linux as we consider *nix system users as less interesting for advertisers.

You can also set Referer of your choice by typing it into the Setup Referer field. Leave the field empty to use the default Referer.

Hide your IP address

Stealth Mode cannot hide your IP address. However, we can conceal it so that websites you visit will take you for a proxy server. Sometimes, it helps, and websites ignore your real IP.
You can set a random IP that you would like to be perceived as yours by simply typing it into the corresponding field. Leave the field empty to use the default IP address.
