Polar specifics worth knowing. Polar's AccessLink API is the official path Freddy uses; it returns sleep, training sessions, daily activity, Nightly Recharge, Cardio Load, and SleepWise data depending on which Polar device you have. The Vantage V3 and Pacer Pro expose the full set; entry-level trackers (Ignite, Unite) expose sleep and training but not Nightly Recharge. Freddy reads whatever your account exposes; if a metric is missing in Claude, it is usually because your specific Polar device does not record it.
If you wear a Polar Verity Sense or H10 chest strap and use Polar Flow's manual entry, those workouts also show up in the API and Freddy will pull them.
