As of version 3 of the reCaptcha, adding this functionality to your website makes the logo of Google appear on all pages of your website. 
The plugin loads 2.5 seconds after the page has loaded. This is because we need to give Contactform 7 time to show its form.
The plugin will work on most WordPress installations, there’s hardly any php code, so hardly any server requirements. 
At this point in time it does require jQuery, which is handled automatically.

This plugin hides the Google reCaptcha Version 3 logo on all pages except the pages that contain a Contactform 7 form.

Masking options are accessible via tag generator panel.

Using latest Wordpress as of May 5th 2016, and it does NOT work. If you're going to install this plugin, you might as well contribute with those 1-stars.
Until this gets updated and more support, I'm gonna tell everyone to stay away this. Time to find a real solution.



It Doesn't Work!

Don't Work in new versions.
