Outside of WordPress

Hi,

I would like to know if it’s possible to use this plugin (partially) outside of wordpress. Beside my wordpress-installation I’m hosting some html-documents, which I would also like to cover.
I tried to just transfer the rendered gdpr-code into my html-documents. but that doesn’t work properly. Clicking on “I agree” -> “We could not verify the the security token. Please try again”. What can I do?

Cheers,
Steven
