In one paragraph
Massachusetts H 78 would create the Massachusetts Consumer Data Privacy Act, giving consumers rights over personal data, including opting out of profiling for solely automated decisions with legal or similarly significant effects. After a hearing on April 9, 2025, the committee folded it into new draft H4746 on November 17, 2025, which was referred to House Ways and Means; the page shows no later action. Separately, Senate bill S2619 is in a conference committee (June 2026). Neither bill has passed both houses.
