COPPA (Children's Online Privacy Protection Act, 1998) protects children's personal information and safety online.
FERPA (Family Educational Rights and Privacy Act, 1974) protects children's personal information and data.
People or companies can get parental permission to bypass COPPA and FERPA laws.
