Massachusetts Data Privacy: A Plain-Language Overview
No comprehensive consumer privacy law (as of 2026)
Status: The state has not passed a general privacy law, but robust data security regulations (201 CMR 17.00) and sector-specific laws remain in full effect.
Massachusetts does not currently have a single, omnibus consumer privacy law like those found in California or Virginia. Instead, data protection is governed by strict data security regulations that require businesses to safeguard personal information against unauthorized access. General consumer protection statutes also prohibit unfair or deceptive data practices.
Rights residents generally have
- Right to be notified of data security breaches
- Right to reasonable security of personal information (implied requirement on businesses)
Who it generally applies to
Applies broadly to virtually all entities that handle or store the personal information of a Massachusetts resident, regardless of the company's location, provided the data is not already covered by federal regulations like HIPAA.
