Hi.
The plugin is just a simple login captcha. It adds the captcha to the WordPress login form, and the WooCommerce login form. It is not intended to be used in other custom forms made with form plugins, which I assume is what you are asking.
When I have more time I will make a new plugin, which will be for many different forms. I will try to make it compatible with some popular form plugins as well, but I don’t think I will buy pro plugins just for that (someone may send it to me though, for testing). But all this will probably not be soon, so I doubt it helps you, sorry.
Regards.
