GM my friends!

Anyone know of any kids phone/OS that is open source, privacy/security intentional, with good parental controls on it?? 
Similar to a Bark or Gabb phone? But not running a bunch of kids data through a centralized company?!?

Just looking for talk and text when our kid isn’t with family. But want to be able to keep “non-contacts” from calling/texting in.
