Google invests in Flo Health to bring period tracking to wearables
Google announced a multi-year partnership with and an investment in Flo Health, the menstrual-cycle tracking app that says it has more than 80 million monthly users; the investment amount was not disclosed. Starting in early 2027, Flo's cycle insights will connect to Google's health platform and combine with wearable measurements including sleep stages, resting heart rate, heart rate variability, skin temperature and respiratory rate, while the companies also plan women-specific products and research into perimenopause, pregnancy and postpartum recovery. Google says data sharing requires explicit permission given separately for each data type and purpose and can be withdrawn at any time, that Flo data will never be used for advertising or sold, and that Google Health Coach algorithms are designed not to log or store sensitive women's health events. The announcement comes after a consolidated class action over period-tracking data allegedly shared with Google and Meta between 2016 and 2019, in which Google and Flo settled for a combined $56 million while Meta did not settle and was found liable under California privacy law.
It wires sensitive women's health data directly into an AI coaching and wearable ecosystem, renewing scrutiny of big-tech privacy promises after a costly settlement.
