Consumer Neural-Data Law
A wave of statutes has begun to regulate neural data outside the medical system, where clinical protections (in the U.S., HIPAA) do not apply. In 2024 Colorado amended its Privacy Act (HB 24-1058) to add 'neural data' to the categories of sensitive data, becoming the first U.S. state to do so; California followed by amending the CCPA (SB 1223) to include neural data within sensitive personal information. Other states, such as Montana, have extended existing genetic- or biometric-privacy frameworks to neural data.
These laws typically require opt-in consent for processing sensitive data, purpose limitation, and rights of access and deletion. Their reach and definitions vary — some cover only data from devices intended to measure nervous-system activity — and enforcement and interaction with federal law remain untested. They mark a shift from aspirational neurorights toward enforceable, jurisdiction-specific rules, but coverage of inferences (as opposed to raw signals) is often ambiguous.
Much consumer neurotech (focus trackers, meditation headbands) sits in this newly-regulated but still lightly-policed space; the gap between a statute existing and it being enforced against inference-based harms remains wide.
