    Five US states enact location privacy laws banning sale of precise geolocation data

    The enactment creates baseline protections for location data while highlighting enforcement gaps that could limit effectiveness. Connecticut, Maryland, New Jersey, Oregon, and Virginia have enacted new consumer privacy statutes that prohibit the sale of precise geolocation data. The laws vary in their consent and minimization requirements, but all share a ban on data sales. None of the statutes provide an explicit private right of action for consumers.
