The people who post their works on this app, do they get paid? Or do their supporters pay them? Depending on the popularity of their work, do they get an income?
Asking for a friend <3
If you upload your work for free you don't get paid.
If you upload your work for sale - and somebody buys it - you might get paid - you might not if the amount for the tax clearance etc. exceeds the amount you were paid or the amount you received is below itch.io's minimum payout amount...
If nobody buys your work - you won't get paid.
