Hey guys - Dawson here (founder) let me know if you have any questions about Logojoy / the story.
It doesn't appear that you provide any attribution at all to the icon creators wherever you display the icon, and I have no idea what license you deliver to the end user (I haven't went through purchasing a logo - knowing that you're just sticking some text with a noun-project icon doesn't strike me as worth it, honestly). Are you in the clear to be displaying these icons with no attribution, and are the users that buy your icons clear to be putting it on websites and business cards without attribution?
I haven't even looked into whether your font usage is appropriate, can you clarify that as well?
