FAQ from Fitness AI Connector
How does authentication work?
You sign in on Garmin’s own page using OAuth 2.0 with PKCE. The Fitness AI Connector never sees or stores your Garmin password.
What data can I access?
Daily wellness (steps, heart rate, sleep, stress, Body Battery, HRV), activities (runs, rides, swims with pace/distance/calories), activity details (pace zones, HR zone distribution, lap splits), body composition (weight, BMI, body fat %, muscle mass), long‑term trends, and profile information (VO₂max, fitness age).
How does it compare to self‑hosted open‑source alternatives?
Fitness AI Connector uses the official Garmin Health API, requires no setup, works on mobile/web, and never shares your password. Self‑hosted options offer more tools and full history but need local installation, use an unofficial API, and store your Garmin credentials.
Can I delete my data or disconnect?
Yes. You can disconnect from your Garmin account settings at any time or request data deletion. After a 30‑day recovery window, your data is automatically purged.
Does it work on mobile?
Yes. Because the server is hosted, it works on both web and mobile chat interfaces in ChatGPT and Claude.
