ProPublica reports some online pharmacies selling abortion pills are using tracking technology that shares sensitive data with third parties, which could potentially lead to prosecution from law enforcement. ProPublica said it found web trackers, including a Google Analytics tool, on at least nine of 11 sites selling the pills. Data shared through the trackers include web addresses visited, items clicked on, search terms, and location and device information, as well as a unique identifier linked to a user's browser.
