Privacy Policy for SwimAnalytics

Introduction

SwimAnalytics ("we," "our," or "the app") is committed to protecting your privacy. This Privacy Policy explains how our mobile applications (iOS and Android) access, use, and protect health data from your device.

1. Health Data Access

SwimAnalytics integrates with your device's native health platform to provide swimming workout analysis:

1.1 iOS - Apple HealthKit Integration

On iOS devices, SwimAnalytics integrates with Apple HealthKit to access swimming workout data. We request read-only access to:

• Workout Sessions: Swimming exercise sessions with time and duration
• Distance: Total and lap-by-lap swimming distances
• Heart Rate: Heart rate data during workouts
• Active Energy: Calories burned during swimming sessions
• Swimming Stroke Count: Stroke data for analysis

Apple HealthKit Compliance: SwimAnalytics adheres to all Apple HealthKit guidelines. Your health data is processed entirely on your iOS device and never leaves it. We never share HealthKit data with third parties, advertising platforms, or data brokers.

1.2 Android - Health Connect Integration

Android Permissions: These permissions are requested during the app's first launch. You can revoke these permissions at any time through Android Settings → Apps → Health Connect → SwimAnalytics.

1.3 How We Use Health Data

All health data is used exclusively for the following purposes:

• Workout Display: Show your swimming sessions with detailed metrics (distance, time, pace, heart rate)
• Performance Analytics: Calculate pace zones, stroke analysis, CSS (Critical Swim Speed), and sTSS (swim Training Stress Score)
• Progress Tracking: Display performance trends, personal bests, and workout summaries
• Data Export: Allow you to export your workout data to CSV format for personal use

The only time data leaves your device is when YOU explicitly choose to export your workouts to CSV format and share the file yourself.
