If you are on the free plan, your loyalty widget will have "Powered By Glow" at the bottom of it with a link to the Glow website. You can translate the "Powered By" portion of this in your translation settings.
If you'd like to remove the glow branding completely, you can upgrade to any of the monthly paid plans. When you upgrade, the branding will be automatically removed.
This even includes Sprout plan for only $9 per month!
