You shouldn’t buy this!
In 2021, Gravity Wiz contracted me to fork this plugin. Since then, they’ve launched Gravity Perks Google Sheets, and you should buy that instead. It’s way better, and I helped build it. Check out the software I offer now or hire me to build the plugin you need at https://breakfastco.xyz/ I am listed on the Gravity Wiz Recommended Developers page.
