It is an valid COPPA workaround for a vendor, in their terms, to tell a teacher that to comply with COPPA, for them to sign up the student.
Such as from Canva.
The question that I always have from abroad is the impact of COPPA etc. I was once told that we are not in America so it does not matter, yet many of the applications originate from America. That is something that has always stumped me.
Look forward to reading your annotations.
