October 19, 2020

As part of our ongoing efforts to enhance the security and privacy of Google Fit for developers and users, we've made some changes to the Google Fit policies and APIs:

There is a new Google Fit Developer and User Data Policy. Please review the policy, and if relevant, make appropriate changes to your apps and services.
Write-access will now only let our app read data it has written. To continue reading data written by other apps from the Google Fit platform, update your code to request read-access scopes for the relevant data types.
Heart rate data has its own scopes.
Sleep data has its own scopes and a new data type.

These changes to the API will be available for developers to use from 19 October 2020 and become enforceable on 27 April 2021.
