Period Tracking Apps, AI, and The Weaponization of Data
By: Jahanvi Chawla // July 2026
With the recent growth of wellness trends and an abundance of health information available at our fingertips, digital health applications have transformed how individuals understand and manage their well-being. For millions of people, period tracking apps have become an essential tool for managing reproductive health. These platforms offer users help understanding their symptoms, tracking their cycles, and predicting ovulation. The same information that makes these apps valuable for personal health also poses a threat in security contexts. In wake of the Supreme Court’s 2022 decision to overturn Roe v Wade, concerns surrounding reproductive surveillance have increased. Digital tools designed to promote wellness and autonomy can be weaponized for legal and commercial interests.
Period tracking apps collect far more than a user’s menstrual cycle, many encourage users to log sexual activity, contraception use, pregnancy injections, medications, and physical symptoms. When combined with other data and internet activity, these records create detailed profiles for users and their reproductive lives. Advances in AI have also made this data more valuable as AI systems using biometric and behavioral data can predict pregnancy with up to 92% accuracy. These risks associated with period tracking apps can be especially apparent when looking at states with high restrictions on abortion access. In 2021 specifically, after the passing of the Texas Senate Bill 8 surrounding abortion, private citizens are able to file lawsuits against individuals who aid or abet abortion after six weeks of pregnancy. These “bounty hunters” are able to utilize digital evidence in these investigations bringing concern that data can be used by law enforcement and is not private.
One investigation showed how a commercial data broker was able to sell a week’s worth of location data tied to users of a period tracking app for just $100. This showed how little control users have once their information is on the app. Even without names attached, location can be combined with other publicly available information to identify individuals. Period tracking apps are not inherently harmful, they provide health insights and empower individuals to better understand their bodies. The issue surrounds the utilization of the data and in protecting consumer privacy.
For users who remain concerned about sharing sensitive information, there are several alternatives to mainstream apps such as paper calendars and monitoring without creating a digital record. The best option depends on how much convenience a user is willing to trade for privacy.
