Privacy Policy

Last updated: February 28, 2026

1. Information We Collect

When you create an account, we collect your email address, name, and profile information provided through our authentication provider (Clerk). When you make a purchase, payment information is processed directly by Stripe and we do not store your credit card details.

2. Garmin Connect Data

When you connect your Garmin account to PaceCoach AI, we access and store the following data from Garmin Connect:

  • Activity data — sport type, distance, duration, pace, heart rate, power, cadence, elevation, training effect, and activity name
  • Health metrics — sleep duration and stages, heart rate variability (HRV), resting heart rate, stress levels, body battery, and daily step count

This data is used solely to provide you with training analytics, performance tracking, fitness/fatigue modeling (CTL/ATL/TSB), race predictions, and personalized AI coaching insights. We do not sell, rent, or share your Garmin data with any third parties for advertising or marketing purposes.

3. How We Use Your Information

  • To sync and display your training activities and health metrics
  • To calculate training load, fitness, and fatigue metrics
  • To generate race predictions based on your performance data
  • To provide AI-powered coaching analysis of your training
  • To process your transactions
  • To send you transactional emails (welcome, subscription updates)

4. Data Storage and Security

Your data is stored securely in our database hosted on Supabase (PostgreSQL). We use Row Level Security (RLS) to ensure data isolation between users. Garmin authentication tokens are encrypted at rest using AES-256 encryption before storage.

5. Third-Party Services

We use the following third-party services:

  • Garmin Connect - Activity and health data sync (with your explicit authorization)

6. Data Retention and Deletion

Your activity and health data is retained as long as your account is active and your Garmin connection is linked. You can disconnect your Garmin account at any time from Settings, which will stop further data syncing. You can request complete deletion of your account and all associated data (including synced Garmin data) at any time by contacting us.

7. Your Rights

You have the right to:

  • Access all data we have stored about you
