I have a pro version of unity, and a friend/friends would like to develop a free game. They do not own pro versions. Obviously it is not legit to develop with free and publish with pro, but is it legit to develop with pro and publish for free/using free? We have no intentions of selling the game.
I don’t think that should be a problem. Even when it’s not “allowed” since you use it for private use nobody will notice it
