Privacy Policy

ZoneMinutes — Last updated: March 2, 2026

Overview

ZoneMinutes is a local-only iOS app that tracks your weekly moderate- and vigorous-intensity exercise minutes using data from Apple Health. Your privacy is fundamental to how this app is designed: no data ever leaves your device, and there are no servers, accounts, or analytics.

What Data ZoneMinutes Accesses

Apple Health Data (Read-Only)

ZoneMinutes reads the following data from Apple Health with your permission:

• Workout records (type, duration, calories, distance)
• Heart rate samples associated with your workouts

This data is used solely to calculate how many minutes of each workout qualify toward your weekly exercise goal. ZoneMinutes never writes data to Apple Health.

Data You Provide

• Age — used to calculate your maximum heart rate
• Settings preferences — formula selection, heart rate thresholds, weekly goal, unit preferences, and week start day

Purchase Information

ZoneMinutes uses Apple's StoreKit framework to process a one-time in-app purchase. All payment processing is handled entirely by Apple. ZoneMinutes does not receive, store, or have access to your payment details.

How Your Data Is Stored

All data stays on your device:

• Settings are stored in local app storage shared between the app and the home screen widget.
• Trial start date is stored in the iOS Keychain to persist across reinstalls.
• No database or file-based storage is used for health data. Workout and heart rate data is read from Apple Health on demand and is never copied or cached by ZoneMinutes.

What ZoneMinutes Does NOT Do

• No data collection: No health data, usage data, or personal information is collected or transmitted off your device.
• No analytics or tracking: There are no analytics SDKs, advertising identifiers, or tracking of any kind.
• No network connections: ZoneMinutes makes no network requests. The only network activity is Apple's StoreKit framework verifying your purchase, which is handled by iOS itself.
• No third-party SDKs: ZoneMinutes uses only Apple's built-in frameworks (HealthKit, StoreKit, WidgetKit, Swift Charts).
• No accounts or cloud sync: There are no user accounts, logins, or cloud storage.

Children's Privacy

ZoneMinutes does not knowingly collect any information from children under 13. The app requires access to Apple Health workout data, which is controlled by the device owner through iOS parental controls.

Your Choices

• Apple Health permissions: You can grant or revoke HealthKit access at any time in iOS Settings > Privacy & Security > Health > ZoneMinutes.
• Delete your data: Uninstalling ZoneMinutes removes all app settings and stored preferences. Your workout and heart rate data remains in Apple Health, managed by iOS.

Changes to This Policy

If this privacy policy is updated, the revised version will be posted here with an updated date. Since ZoneMinutes has no way to contact users (no accounts, no email collection), checking this page is the only way to see changes.
