For families
Access without silent data collection.
Private use is the default. Personalized support and any contribution to model improvement are separate, purpose-specific choices with different controls.
04 / Family trust
A useful learning tool should make its boundaries understandable before asking for trust.
01
Private by default
A question does not become training data.

02
Separate choices
Support and contribution are not one checkbox.
Authorization states distinguish private sessions, personalized learning, and voluntary contribution. Real learner authorization cannot be self-issued in the research build.
03
