12. AI Transparency Statement

Coach Vita, our AI coaching assistant, uses data from connected third-party services — including Garmin — to provide personalized fitness coaching. When you connect a service, the following data may be processed by AI:

• Sleep scores, duration, and sleep stage breakdowns
• Heart rate variability (HRV) measurements
• Stress levels and Body Battery data
• Activity summaries (type, duration, distance, heart rate)
• Daily health summaries (steps, resting heart rate)
• Weight and body composition measurements
• Recovery scores and strain data

This data is sent to Anthropic's Claude AI API to generate contextual coaching advice, workout adjustments, and recovery recommendations. The AI does not make medical decisions and its output is informational only.

Data sent to the AI is processed per Anthropic's Privacy Policy. Anthropic does not use API inputs/outputs to train its models. Your health data is not stored by the AI beyond the duration of each conversation session.

You can disconnect any third-party service at any time from Settings, which will stop that data from being included in AI coaching context.
