Well over a dozen U.S. states now have omnibus data protection laws in effect. On October 1, 2025, Maryland will join their ranks with the Maryland Online Data Privacy Act (the "MODPA").

Key Takeaways

  • Maryland's new data protection law, the Maryland Online Data Privacy Act (MODPA), takes effect October 1, 2025, and introduces stricter requirements for processing personal and sensitive data, especially for minors, compared to other state laws.
  • Businesses should care because MODPA imposes heightened restrictions and prohibitions on the use of sensitive data and data of individuals under 18, increasing compliance obligations (beyond what is common under other U.S. state data protection laws) and the risk of enforcement actions by the Maryland Attorney General.
  • To prepare, businesses operating in Maryland should review and update their data collection, processing, and privacy practices to ensure they only process data that is strictly necessary for requested products or services, obtain opt-in consent for sensitive data, and implement robust consumer rights request procedures.
