The ultimate Online Privacy Test Resource List

Whenever you connect with a program to an Internet resource, a web browser to a website for instance, information are revealed to the server hosting the resource.

That's automatic, and often not the only thing happening. If that site loads resources from other servers, they too gain information, and depending on what is running on the site and supported by the browser, additional information may be revealed.

Usually, information such as your computer's IP address, a user agent that reveals browser, operating system and language, and a handful of other information are revealed automatically during connections.

While there are methods available to hide or block certain information from being made known to sites you connect to, there are also methods that sites can use to find out more about you.

Online Privacy Test Resource List

ip-address-leak

Online privacy tests help you find out what kind of information your browser (or other programs) reveal.  The information itself is useful, but you can also act upon it, for instance by disabling certain features in the program you are using if you don't require them.

You find two listings below. The basic tests listing contains resources that perform simple tests (usually one) only while the advanced tests listing resources that run a series of tests.
