Personal Health Dashboard is a personal, single-user tool.
With the user's consent through Google OAuth, the app reads read-only health data from the Google Health API: weight, body fat percentage, calories, and step counts.
The data is used only to draw charts on the user's own dashboard. It is not sold, shared with third parties, or used for advertising or any other purpose.
Data is fetched on demand and cached temporarily in memory on a private server. It is not published. The OAuth refresh token is stored only on that private server.
Access can be revoked at any time from the Google Account permissions page, and the app then loses all access to the data.
This policy may be updated if the app's behavior changes.
