We recently got a crash report from a user that made us aware that she/he was using a cracked version of HyperNotes Free. It has been cracked in such a bad way that it just crashes during normal usage.
We cannot and we won’t fix that problem since it is unrelated to our original work. If you happen to use a copy of HyperNotes from any other source than the Google Play store then you most likely have a cracked version that does not function correctly. Even worse it could be infested with trojan code or other harmful exploitations.
We advise you to uninstall that cracked copy and get the original version from Google Play.
