Maryland Online Data Privacy Act of 2024

Maryland's comprehensive consumer privacy law gives residents rights to access, correct, delete, and port their personal data, to get a list of categories of third parties that received it, and to opt out of targeted advertising, sale, and significant-decision profiling. It is stricter than most state laws: data collection must be limited to what is reasonably necessary for a requested product or service, sensitive data may be collected only when strictly necessary and may never be sold, and minors' data may not be sold or used for targeted advertising. A 2026 amendment (HB 711, ch. 874) extends sensitive data to inferences and bars knowing sales of personal data to government units engaged in civil immigration enforcement.
