PERIOD TRACKERS COLLECTING AND SHARING USER DATA

Period tracking apps are systematically gathering sensitive health information and transmitting it to advertisers, data brokers, and other external companies. The apps typically collect details about cycle patterns, symptoms, and sexual activity—data that could be used for targeted advertising or sold to the highest bidder. Users often have limited visibility into data sharing practices buried in lengthy terms of service. Many apps lack strong encryption or security protections for this particularly sensitive information. The findings highlight a broader privacy problem in the health tech space. Users seeking convenient health tracking tools often trade detailed personal data for app functionality without fully understanding the consequences. Privacy advocates recommend reviewing app permissions, reading privacy policies, and using apps with transparent data practices. Users concerned about reproductive data privacy should consider local, encrypted alternatives or pen-and-paper tracking methods.
