Privacy Policy

Last updated: June 1, 2026

Zone2 ("the app") respects your privacy. This policy explains what we collect, how we use it, and your choices.

Information We Collect

• Health & fitness data: with your permission, we read heart rate, resting heart rate, and date of birth (to estimate age) via Apple Health (HealthKit), and may write your Zone 2 workouts back to Apple Health.
• Workout records: date, duration, average/maximum heart rate, and time spent in each heart-rate zone.
• Account data: when you sign in with Google, we receive your email, name, and account identifier to identify your account.

How We Use It

• To calculate and display your heart-rate zones, Zone 2 time, and training statistics.
• To sync your workouts to our server so you can view history across devices.
• To identify your account and keep your settings.

HealthKit Data

Health data obtained through HealthKit is used solely to provide the app's training features. We never use HealthKit data for advertising or marketing, and we do not sell or share it with third parties.

Data Sharing

We do not sell your personal data. Apart from cloud hosting needed to provide the service, we do not share your health or workout data with third parties.

Retention & Deletion

Workout records are stored on your device and on our server. You may sign out in-app, or email us to request deletion of your account and associated data.

Your Choices

• You can revoke the app's Health access anytime in iOS Settings → Privacy & Security → Health.
• You can sign out anytime or email us to request data deletion.
