Authorize with Google
The user signs in with Google and grants the Google Health read-only health metrics scope.
Private desktop health export utility
Codex Fitbit Health Desktop is a personal-use desktop helper that reads the signed-in user's own Google Health health metrics, including Fitbit-synced weight and body-fat measurements, after explicit Google OAuth consent.
How it works
The user signs in with Google and grants the Google Health read-only health metrics scope.
The desktop helper fetches weight and body-fat records synced from Fitbit-compatible devices.
OAuth tokens and exported measurement files are kept on the user's computer, not on this website.
The user can delete local files and revoke Google access from their Google Account permissions page.
Requested Google scope
The app requests only the scope required to read Google Health metrics and measurements:
https://www.googleapis.com/auth/googlehealth.health_metrics_and_measurements.readonly
