Medical Sources & Limits

The primary references behind Ready Trainer One's health information, and what RTO is — and isn't — for.

AI data handling

RTO uses Anthropic's Claude for AI coaching. Anthropic's API terms say Customer Content is not used to train Anthropic models.

• Anthropic Commercial Terms of Service
• Anthropic Data Processing Addendum
• How Anthropic protects the personal data of Claude users (Anthropic's plain-language summary)

For our own end of the pipe — what RTO sends, what it doesn't, and how to withdraw consent — see the Privacy Policy, §3.

Apple Health & HealthKit

RTO is built on Apple HealthKit. The user-privacy posture and data-source guarantees we rely on are documented by Apple:

• Apple Developer — Protecting user privacy (HealthKit)
• Apple Human Interface Guidelines — HealthKit

Critical AI health literacy

How patients, clinicians, and tools should think about AI in health contexts — the posture that informs the way RTO presents AI output:

• National Academy of Medicine — Critical AI Health Literacy as Liberation Technology (Campos et al., perspective)

GLP-1 medications

For dosing, side effects, warnings, and storage of GLP-1 receptor agonists, the primary U.S. patient references are on MedlinePlus (NIH / National Library of Medicine):

• Semaglutide (Ozempic, Wegovy) — MedlinePlus
• Tirzepatide (Mounjaro, Zepbound) — MedlinePlus

RTO does not change your prescription, dose, or schedule. Any change to medication should come from your prescriber.

Hydration

• Dehydration — MedlinePlus (signs, severity, when to seek care)

Physical activity

• CDC — Physical activity basics: adults (current U.S. guideline)

Sleep

• CDC — About sleep (recommended duration and behaviors by age)
• Healthy sleep — MedlinePlus

Sports nutrition & fueling

• Nutrition and Athletic Performance — joint position stand (Academy of Nutrition and Dietetics, Dietitians of Canada, American College of Sports Medicine — Medicine & Science in Sports & Exercise, 2016)

Heart rate variability (HRV)

RTO surfaces HRV as a recovery signal alongside sleep and resting heart rate. HRV is informative when interpreted conservatively — it is not a diagnostic instrument and does not detect disease.

• An Overview of Heart Rate Variability Metrics and Norms (Shaffer & Ginsberg, Frontiers in Public Health, 2017)

Limits

• RTO is not a medical device.
• RTO does not diagnose or treat disease.
• RTO does not change medication dosing.
• The presence of a citation on this page does not mean RTO's personalized output has been clinically validated.
• AI output can be wrong or incomplete. Check with a clinician before medical decisions.
