Experts warn that period tracker apps pose privacy and safety risks to women, as personal information can be collected and sold.
A report from the University of Cambridge highlights that menstrual data, including exercise, diet, and sexual preferences, is a 'gold mine' for consumer profiling and targeted advertising.
The popularity of period tracking apps has surged, with over 250 million downloads for the top three apps, making cycle tracking apps a lucrative business due to the valuable user data they provide.
Researchers caution that in the wrong hands, data collected by these apps could lead to health insurance discrimination, risks to job prospects, or even domestic abuse.
The research team advocates for better governance of the 'femtech' industry, improved data security, meaningful consent options, and the development of public health alternatives to commercial tracking apps.
