Coverage from Advocate News, The Reading Post, and others
The Massachusetts Consumer Data Privacy Act is legislation considered by the state legislature to establish consumer rights and duties for organizations handling personal information.
Its provisions include rights to access, correct, delete, and transfer data, as well as limits on collection, retention, and targeted advertising. The bill also proposes heightened safeguards for sensitive information, including precise location data, and protections for minors. Its enforcement framework includes authority for the Massachusetts Attorney General and a private right of action; House passage and the reconciliation of legislative versions form part of its advancement.
