Health apps can help you track your steps, workouts, heart rate, sleep, or even your menstrual cycle. They’re built into many phones (like Apple Health, Samsung Health, and Google Fit) or downloaded separately (like Strava and Flo). These apps are super convenient, but they also collect some of the most private and sensitive information about you!
And here’s the thing: not all health data is protected, especially if you’re using a regular app instead of visiting a doctor. That means your information (like how often you run, when you ovulate, or how much you sleep) can be stored, shared, or even sold by the company who owns the app.
HERE is a review of the privacy of common reproductive health apps (for periods, pregnancy, fertility, etc.)
What You Can Do to Protect Your Health Data
- Turn off cloud backups for health and fitness apps if you don’t want your data stored online.
- Use a strong phone passcode and/or password for the app if the option is offered.
- Review app permissions (Does your step counter really need access to your microphone or contacts? Probably not. Click HERE for how to change iPhone settings. HERE for Android.)
- Avoid logging very sensitive health data in the apps.
