Maryland’s Online Data Privacy Act, passed by the state’s legislature on April 6, 2024, and awaiting the governor’s signature, will bring forth data minimization requirements that are among the broadest and most strict in the U.S. to date. Days before Maryland sent the law to the governor for signature, the California Privacy Protection Agency published its first enforcement advisory on data minimization under the CCPA. This article explores the nuances of Maryland’s data minimization provisions compared to other state data privacy laws, including California’s, and offers practical compliance takeaways. See “How to Comply With the CPRA’s Data Minimization Standards” (Feb. 8, 2023).
