Google has announced a multi-year partnership with Flo Health, the period and women’s health app. Starting early next year, you’ll be able to sync Flo with the Google Health app. Google’s post is dated October 12, 2026, so that points to early 2027.
There are two catches. The data link runs in both directions, and the cycle-aware coaching Google is promoting requires a paid Google Health Premium subscription.
How the Flo and Google Health link works
With your consent, Flo cycle data can be linked with your Google Health metrics. Google’s examples are resting heart rate, heart rate variability, skin temperature and sleep stages.
Data also moves the other way. Google says data from your Google Health app will be made available to Flo, for a more personalized experience across both apps. That direction is easy to miss in the announcement, and it is worth weighing before you grant access.
Google says the permissions are granular and can be revoked:
No data will move between the apps without your explicit permission — given separately for each type of data and each purpose — and you have the control to withdraw permission at any time.

Google also promises that Flo data shared with Google Health will never be used for advertising or sold. It says that data won’t be offered to other apps or developers through its health platforms either. These are Google’s own commitments. Google’s post doesn’t explain how they will be enforced or audited.
What Google Health Premium unlocks
The tailored, cycle-aware coaching needs Google Health Premium, sold separately. So does the Google Health Coach integration, which Google says will connect your cycle, sleep and recovery data. The fine print also requires the Google Health app and an internet connection.
It’s the same pattern we flagged when the Fitbit Edge launched with Coach behind a Premium plan. Google’s announcement names three wearables in this context: the Google Fitbit Air, the Pixel Watch 5 and the new Google Fitbit Edge.
The rest of the partnership
Google describes four pillars. App syncing and the Coach integration are the first two. The third is research on underserved topics. Google says those may include perimenopause, polyendocrine metabolic ovarian syndrome (PMOS), pregnancy and postpartum recovery.
The fourth pillar is new products designed specifically for women. Google’s post doesn’t describe what those products are.
Google says Flo is used by more than 80 million women every month. That figure is Google’s own, and we haven’t verified it. Google’s post also lists no launch regions and no financial terms for the deal.
Flo’s privacy history
Flo’s handling of user data has been tested in court before. Google and Flo are both settling defendants in Frasco v. Flo Health, Inc. (N.D. Cal. No. 3:21-cv-00757-JD), a US privacy class action. It concerns period and pregnancy data from Flo users between November 2016 and February 2019. The defendants deny the allegations.
That history is why the consent screens matter here. Google’s promises sound strong on paper, but read each permission before you link two apps holding health data this sensitive.
