Plugin and GDPR compatibility

I have a plugin hosted in www.remarpro.com. The plugin consists of inquiry form to be submitted by the visitors in the front-end. I have followed the 4.9.6 update regarding GDPR. I have also added exporter and eraser in my plugin. Is there something I need to add more in my plugin? Is there something I have to add in my inquiry form to make it GDPR compatible?

Any help would be appreciated.
