I just found this in the Terms Of Service on the cc website:
2.Age Requirement. Cubic Castles is a game intended for all audiences. By accepting the Terms of Service when playing Cubic Castles, you affirm that you are of 13 years of age or older. If you are under 13 years old you may play with parental supervision. Child safety is a high priority for Cosmic Cow. As such, children under the age of 13 may create an account only with parental supervision. Account emails must be those of a parent or guardian if an email is provided.
