I hate to disappoint but I cannot make any such guarantees. Running
php artisan plugin:refresh for example would certainly reset the plugin data. Additionally, were you to uninstall it and then re-install through the OctoberCMS marketplace, well that would also clear your settings. I recommend that you check out the demo site first and see if what you see there would fit your requirements. You can also ask me about whether the plugin has any specific functionality you might have in mind. If you do end up purchasing, I'll be here to support you if you need.
