Hello @colomet,
There is already a provision for that in the plugin. You can navigate to your site Dashboard-> Huslte-> Setting-> Data-> Uninstallation. Select the Reset Option & Save Settings.
This will delete all the modules and their data – submissions, conversion data, and plugin settings when the plugin is uninstalled. This will itself clean the DB( just limited to the Hustle plugin), remove all the tables relating to the plugin from the DB too.
Should you have any doubts or need any help feel free to reply in the thread here and we would be happy to help!
Regards,
Prathamesh Palve
