If at any point you want to stop Google Fit from collecting data, you can disconnect your apps and devices by following these steps:

  1. Find Google settings in one of these places (depending on your device):
    • A separate app called Google Settings Google Settings
    • In your device's main Settings app Settings app, tap Google.
  2. Under "Services," tap Google Fit.
  3. Select the app or device that you wish to disconnect.

If you disconnect an app from Google Fit, it will be disconnected on all devices where that app is installed. Disconnecting an app will not delete any data that the app stored in Google Fit.
