Unclear with free month trial – Hopster: ABC Games for Kids Review

I signed up April 25th, assuming I would get a full free month, then was charged May 2nd for a month. Not sure if customers that want a full free month have to start at the beginning of any given month to get it or if it was a mistake to charge me. Either way, a good app starts with good pricing and ethical morals, so for now I'm leaving the 1 star.
