Untracked Privacy Policy

Last updated: March 30, 2026

Untracked is a workout logging app that helps you retroactively log workouts using heart rate data from Apple Health. Your privacy matters — here's exactly what the app does with your data.

Data We Read

← Heart Rate — to display your daily timeline and detect periods of activity

← Workouts — to show existing workouts and avoid duplicate suggestions

← Body Measurements — age, weight, and biological sex for calorie estimation

← Distance & Steps — to display activity data for workout periods

Data We Write

→ Workouts — workouts you create or edit within the app

→ Active Energy — calorie estimates associated with saved workouts

→ Distance — distance data associated with saved workouts

All reads and writes go through Apple Health (HealthKit) only.

Third-Party SDKs

The app binary includes the Google Mobile Ads SDK. It is currently inactive and does not load, display, or transmit any data.

Background Processing

When you enable Workout Reminders, the app performs a daily background check at your chosen time. It reads today's heart rate data and runs the detection algorithm locally. If untracked workouts are found, a local notification is sent. No data leaves your device.

This feature is opt-in and can be disabled at any time in Settings.

Your Rights

✓ Revoke Health access anytime: Settings → Health → Data Access → Untracked

✓ Disable reminders and background processing in the app's Settings

✓ Delete any workout created by Untracked through the app or Apple Health

✓ Uninstalling removes all locally cached data and preferences

Children's Privacy

Untracked does not knowingly collect data from children under 13. The app requires Apple Health, which has its own age restrictions.
