Depending on the target page and the data structure one tries to extact it can sometimes be helpful. Also it often fails to produce any usable output (=usable output doesn't require intensice data cleaning afterwards that a selfscripted solution is the better approach in the first place).

BUT:
Google Analytics is running in the background, periodical license checks (there are better ways to solve this), uninstall tracking, XHR-monitoring...

So much about no trackers claims.

I just paid for Pro, but am kind of frustrated because I can't find where (in either Options or Manage) to insert the activation code.

Please provide explicit instructions on how to locate the place where that goes. --Thanks.
