This week, we’ve been taking stock of how tech has both helped and harmed Americans trying to get abortions in the two years since the U.S. Supreme Court overturned Roe v. Wade. After the Dobbs decision, some experts warned consumers that menstrual tracking apps would provide a means of surveilling abortion seekers. There was even a social media campaign on what was then Twitter advising people to delete their period trackers. But it’s turned out that the threat to privacy isn’t limited to those apps. Other digital data can actually be more likely to reveal an illegal abortion. That’s according to Albert Fox Cahn, founder of the Surveillance Technology Oversight Project. He told Marketplace’s Lily Jamali that everyday consumer apps generate sensitive data that can be used for abortion surveillance.
