Finally one good opt-in option

I was looking for a plugin that enables using an “optin in” approach, as required by several EU countries, in particular for Google Analytics plugins not to be set before acceptance or at least implicit acceptance given by scrolling.
This plugin makes it possible, easy to set up and provides good options.
Support is good.
I would have given 5 full stars if the styling customisation was more complete. There are a few options in the back office, but with my theme it was not looking good. To go beyond the choices provided in the back office, I had to change the plugin stylesheet.
