Currently, there is no law in Massachusetts or federally to prevent the sale and purchase of cell phone location data. Every day, companies collect and sell sensitive location information from cell phones, revealing information about where we live, work, and socialize.

Here's just one example: Politico recently reported that a data broker company tracked people's visits to nearly 600 Planned Parenthood clinics in 48 states, including Massachusetts. The company sold that data to inform one of the largest anti-abortion ad campaigns targeting specific individuals. If anti-abortion extremists can use cellphone location data to target abortion seekers with ads, they can also use that data to target, harass, or threaten patients and providers in our state.

The Joint Committee on Advanced Information Technology, the Internet and Cyber Security recently reported out the MA Data Privacy Act, a comprehensive data privacy bill that includes provisions to limit data collection and sharing, treat sensitive health and biometric data with extra care, and prohibit the sale of our cellphone location data. But getting out of committee is just step one. The Legislature needs to pass this before the end of July.
