Maryland Data Privacy and Protection Act of 2026
HB 264, the Maryland Data Privacy and Protection Act of 2026, sets new rules for how Maryland state government agencies collect, store, and handle personal information. It requires agencies to only collect personal data that is necessary for a legitimate government purpose, delete or remove identifying details when no longer needed, and post clear privacy notices on their websites. The bill specifically defines "sensitive data" (like racial origin, health information, biometric data, and location tracking) and mandates that agencies designate a Privacy Officer to oversee compliance. This law directly affects all Maryland state government units, including departments and agencies, by requiring them to update their data practices to protect residents' privacy.
