Do Not Track Plus Feature Details
Note:
While we provide the best level of privacy protection available, currently there are some limitations in certain browser versions.
Chrome M16 release: Does not set the Do Not Track header. We attempt to block all tracking requests from being made, but some will still originate although no tracking items will be loaded into the DOM.
Safari: We attempt to block all tracking requests from being made, but some will still originate although no tracking items will be loaded into the DOM.
Firefox v4+: 100% functionality, no limitations.
Features on browser start:
We set opt-out cookies. When you start your browser, we write all the opt-out cookies that we know of to your computer. These non-unique, non-personally-identifiable cookies tell advertisers not to deliver targeted advertisements to you. (You can read more about these cookies at the Network Advertising Initiative). Then, for good measure, we remove all these cookies when you close your browser.
While you are browsing:
We stop tracking requests. Do Not Track Plus examines each outbound request your browser receives. We evaluate that request, and if we think it's a tracking request (like a 1-pixel image or tracking javascript), we block it from being made. If we block the request, then no connection is established between your computer and the remote server for that request. We block tracking requests from third-party domains, as well as first-party requests for known tracking code.
We send the Do Not Track header, which is a new standard of requesting that companies don't track you online. (You can read more about the Do Not Track here.) We think this is great, so we send this header everywhere you go (unless you want to limit it for some reason). However, there isn't an agreed-upon meaning, rule, or regulation for what companies need to do when they see this header. They don't have to respect it and can ignore your request. and even if they say they will, who knows? That's why we also block requests that we think are occurring to track you.
Note: All of the above happens locally on your machine. None of your browsing information is sent to us.
Social buttons:
We disable social buttons by default because they're used for tracking. (For an illustrated, simplified explanation of DNT+'s social button blocking, click here.) When your computer is asked to make requests for social button--for instance, when Facebook "Like" buttons are included on a website with XFBML or an iframe--we block the request from being made. In its place, we put a marker that looks just like a regular button into the same spot on the page so you know that a social button is supposed to be there. If you click on the social button placeholder, we know that you want to share, so we then load the social buttons into the page and active the button you clicked. You'll have to click again to share in case your click was an accident.
On browser close:
Opt-out cleanup. We clean up and remove all the opt-out cookies that were set.
