Policy

LAST UPDATED · OCTOBER 15, 2026

FIT Coach is a personalized AI training and nutrition application ("we"). This policy describes what data we access, how we use it, and your rights regarding it.

Data We Access

With your explicit authorization via OAuth, FIT Coach accesses the following data from connected services:

• Strava: activity records including type, duration, distance, heart rate, power, elevation, pace, and route data for activities you have recorded. We use the official Strava API. You authorize this access via OAuth and can revoke it at any time.
• WHOOP: recovery score, heart rate variability (HRV), resting heart rate, sleep stages and duration, daily strain, workout records, and basic profile data.

We also collect: your email address (for sign-in), name (optional), birthdate (optional), bodyweight, training preferences, and benchmarks you provide.

How We Use Your Data

Data is used solely to generate your personalized training and nutrition recommendations and to operate your account. Specifically:

• Coaching feedback: Your Strava activity data is used to help you understand your training and to generate daily, personalized feedback and workout recommendations that are visible only to you.
• Inference only, never training: Your Strava data and other personal metrics are sent to Anthropic's Claude API for inference (producing your daily prescription) only. Strava data is never used to train any artificial intelligence or machine learning model, by us or by any third party. Anthropic's API does not train models on customer inputs by default, per their terms of service.
• Visible to you only: Per Strava's API Agreement, your Strava activity data is only displayed to you within FIT Coach. It is not shared with other users, displayed in any public feed, heatmap, or leaderboard, or shown in any way you would not expect.

Your data is not sold, shared with advertisers, or used for any purpose other than what is described here.

Strava-Specific Disclosures

In accordance with the Strava API Agreement:

• You agree that Strava may monitor and collect usage data related to FIT Coach's use of the Strava API, and that Strava may use such usage data for any business purpose at Strava's discretion (including ensuring compliance with the API Agreement, providing developer or user support, or improving the Strava platform).
• Strava activity data accessed via the API is displayed only to you, the user who authorized the connection.
• Strava activity data is not used in artificial intelligence model training, machine learning model training, or any similar application.
• You can revoke FIT Coach's access to your Strava account at any time at your Strava settings. Doing so immediately stops all data access; previously synced data is removed within 30 days of disconnection per the deletion process below.

How We Store Your Data

Your data is stored in a private Postgres database hosted on Railway. Access tokens are encrypted at rest. Only FIT Coach systems and authorized FIT Coach staff (for support purposes only) can access your data.

Third-Party Services

FIT Coach transmits data to:

• Anthropic — for inference only (generating recommendations). No customer data is used to train Anthropic's models per their default API terms. Anthropic's privacy policy.
• Stripe — for billing only. We never see your full payment information. Stripe's privacy policy.
• Resend — for transactional email. Resend's privacy policy.
• OpenWeather — for weather context (only your approximate city, not exact coordinates).

Data Retention and Deletion

You can revoke FIT Coach's access to WHOOP at any time at your WHOOP privacy settings and Strava at your Strava settings. To delete your FIT Coach account and all associated data (including all Strava and WHOOP data we have stored), email coach@durangobikeproject.com. We will permanently delete all data within 30 days.

Children's Privacy

FIT Coach is intended for users 18 and older. We do not knowingly collect data from anyone under 18.

Changes to This Policy

We will notify users of material changes by email. The "Last updated" date above reflects the most recent revision.
