Is this medical advice?
No. Ed Winters guides and educates through Ottavia. They never diagnose or prescribe.

No. Ottavia has read their published work and applies it inside your guidance. Your questions go to Ottavia; their thinking comes back in the answer, attributed.
What happens to my health data?
Your data stays in your Ottavia account and is used only to guide you. AI runs on anonymized context, separated from your identity; your personal and health data is never shared with any AI provider, and never sold.
Does Ed Winters see my data?
No. Experts contribute their methods to Ottavia; they never see individual users or their data.
Do I need a wearable?
Ottavia works best with Apple Watch, Garmin or Google Health. You can also log sleep, meals and workouts yourself.
