Thanks for reaching out. We've been doing a ton of investigation into GDPR. Right now, we don't have a good solution integrated into or for Joomla in general. We're investigating multiple options for extending JFBConnect, integration with other GDPR extensions for Joomla as well as some stuff we think may be beneficial to all sites (outside of JFBConnect).
From a high level, I honestly don't think that JFBConnect is the proper place to add GDPR support. There's a lot of logistics that go along with it, it's not 'just a checkbox' on registration and there's a whole lot of complexity that can come along with it, depending on how nuanced you want to ask permission. One box for all communications, or 7 boxes for each newsletter, transactional emails and promos, etc. That really would be a burden on JFBConnect to do properly and/or well.
For now, I'd say that JFBConnect does have the 'manual' registration process (simply turn off Automatic registration) and the user is brought to a registration page after they login the first time. We can show checkboxes that are in the User - Profile extension or from a variety of other community extensions we support. Those checkboxes wouldn't have all the details you need, like IP, type of confirmation, etc to fully comply.. but it's a start.
The other alternative is to use the "New User Registration Redirection" URL in JFBConnect to redirect users to another page on your site that properly collects all this data.
That's all I can recommend for now, but keep an eye out later this Summer for something we're hoping to work on and possibly get out to help make the whole process simpler for any type of registration
Thanks,
