This application ("the app") is a personal home-automation project. It connects to the Google Health API to read heart-rate, sleep, and activity data from a single individual's own Fitbit account, for the sole purpose of triggering that same individual's own home automation system (a locally-hosted Home Assistant instance).
With the account owner's own Google account authorization, the app reads:
Data is used only to detect wake-up events and trigger a home automation scene (such as turning on lights) on the account owner's own private, self-hosted server. Data is processed in real time and is not permanently stored, sold, shared, or used for any purpose other than this personal automation.
No data collected by this app is shared with, sold to, or disclosed to any third party. The app has a single user (its developer) and runs entirely on infrastructure that user owns and controls.
The app does not maintain a persistent database of health data. In-memory state used for detection logic (such as a rolling heart-rate baseline) is cleared on service restart.
Questions about this policy can be directed to the app owner via the support email listed in the associated Google Cloud project.
