Allowing users to view third party internet tracking
Spy Watch is a privacy extension that seeks to improve transparency around online internet tracking by third parties. When a user visits a page, Spy Watch lets the user see every site that knows the user visited that page. For each of these sites, the user can find out what other information the site has gathered about the user's browsing history.
After you install the extension, continue to browse normally. After some time, click on the extension to see who's watching you!

Latest reviews
This extension appears to consume a large amount of CPU and I/O resources. Under certain circumstances, it reads and writes multiple megabytes of data each second using chrome.storage.local. If the developer came up with a more reasonable algorithm for persisting data, it'd be easier to give it a rating based primarily on its features rather than on the quality of its implementation.
As you visit web sites, do you know what third parties are able to see your actions? Spy Watch does not prevent third parties from looking in, but it let's you see who is doing the looking.
A great tool to really understand how various sites extract information and how without realizing we click on all the permissions that the site asks us. Am sure we will be more careful after this. Grat Job
Spy watch is a great way to concretely understand the phenomenon of third-party sites collecting information on your Web behavior.
