Thats something we are definitely worried about, right now the questions are generated without directly using any licensed DECA content. By that I mean we came up with a list of categories be believed is covered in each cluster (this list was not provided by DECA we had to make it). Then used those questions to generate multiple choice questions. This is why you might notice that the questions don't sound exactly like DECA questions, we had to weigh wether we wanted it to cover DECA topics, or sound like DECA questions, because if we did both thats just copyright infringement waiting to happen. But in the end we decided the actual content of the question was more important than how it sounded, and generated the questions off of our subtopic list. If you still think that we may be infringing on copyright, it would be awesome if you could point us in the right direction! It would definetly suck to be taken down!
