ChatOBD2 does not sell, rent, or license manufacturer dealer diagnostic suites. It is an independent OBD-II assistant with brand / OEM ECU paths where the in-app catalog supports them. Brand names belong to their respective owners. Expert AI and repair tips are guidance — the final decision rests with you or your mechanic. Safe driving and legal use are your responsibility.
