Ideally 3rd-party plugins and WordPress Core take care of everything GDPR related on their own and our plugin isn’t needed at all. But as of now (May 2018) taking care of GDPR is fragmented with every plugin developer figuring out the best solution on their own. As a WordPress development agency we figured whenever we help a client get a certain plugin or theme compliant as best we can we might as well share it through the WP GDPR Compliance plugin with the whole community.
