Question: Commercial offline & online usage

[AlexBa]

Hello everyone, We would like to use the emojis for an offline product. Basically, we would like to have stickers printed with the emojis that can be configured online.

As I have read, you are only allowed to use the emojis if you indicate the author (e.g. on the website or on the printed stickers).

My question is whether this is correct? If so, is it possible to buy a paid commercial license so that you don't have to indicate the author?

Thank you in advance!
