A private, single-user tool that brings my own fitness data into an AI assistant.
Personal Health Bridge reads my own health and fitness measurements from the Google Health API and makes them available to an AI assistant, so I can ask questions about my activity in plain language — for example how many steps I walked last week, or how my body composition has changed over a month.
It is a personal project used by one person: its author. There is no sign-up, no other users, and no service offered to anyone else.
The application asks for read-only access to my own Google Health data:
googlehealth.activity_and_fitness.readonly — steps, distance,
calories and workouts, to show activity trends.googlehealth.health_metrics_and_measurements.readonly — weight,
body-fat percentage and heart rate, to track body composition.googlehealth.sleep.readonly — sleep sessions, to relate rest
to training load.googlehealth.profile.readonly — height and age, which are
required inputs for body-composition calculations.No write access is requested: the application only reads. It never sends data to any third party, and it does not use Google user data for advertising, training models, or resale.
Measurements are stored in a private database on a server controlled solely by the author, and are used only to answer that same person's questions. Details are in the privacy policy.
