There is a ‘permitted use’ clause.
This is an art contest.
We are not selling the designs for profit.
It explicitly lists permissible uses.
This usage falls within the permissible uses.
Some of you are far more concerned than Canva is.
They have their own legal team to pursue these matters as they see fit.
They have not chosen to do so, most likely because this is permissible use and hence ridiculous.
If you are that concerned about Canva’s rights, I would suggest you file an intellectual property complaint directly with them. Then, they can decide whether it’s permissible use.
I am 100% confident that they will find this to be permissible use.
Again we are taking about an art contest. 😐
