Since you’re advertising the product in part as an educational product you should include licensing information.
Is the software only legally usable on 1 machine at a time or can a school pay for only one copy and install it on all the machines in their computer room?
Is there a middle ground, e.g. valid for use on up to 6 machines, or is there a discount on further licenses purchased by the one institution?
I’ll be grabbing a copy for myself regardless, but if I think it would be of use to the teachers I work with or children I do projects with, I’d like to know where I stand.
Best of luck
