Your iPhone knows a lot about your health, especially if you use apps like MyFitnessPal or track your activities with your Apple Watch. If permission is given, applications can access this data. Here’s how to check which apps have access to your data.
We’ve shown how it can track your location and provide that data to apps before, but what about your health data? The Health app collects as much data as you can provide, and if you use apps to track your weight, calories, blood pressure, and more, that can be a lot. If you’re wearing an Apple Watch, it may contain even more information than you might think.
How to control which apps can access your health data
There may be some health data that you don’t want to track at all, or there may be others that you don’t mind Apple but prefer not to share with apps. These are all things you can control from the Health app.
To get started, open the Health app on your iPhone and tap Sources at the bottom of the screen.
