There is a growing body of scholarship on how the menstruapps marketplace reinforces heteropatriarchal stereotypes. This study attempts to contribute to this growing body of research, focusing on the erosion of privacy and data autonomy in the menstrual apps (popularly known as ‘menstruapps’) market, using a feminist political economy lens. Through qualitative interviews with digital rights activists and open source technology developers, and a legal review of the privacy policies of four popular mobile applications (apps) in the Global South, this study explores two main questions:

(a) How do menstruapps in the femtech market address privacy (in collection, processing, and thirdparty sharing of personal data)?

(b) What do data practices of dominant menstruapps suggest about data sovereignty? What are the particular implications for users in the Global South?
