Privacy Policy

Last updated: June 10, 2026

Rekur ("we", "our", or "the app") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use the Rekur iOS and watchOS applications.

1. Information We Collect

1.1 Health and Fitness Data (Apple HealthKit)

Rekur integrates with Apple HealthKit to provide heart rate-guided workout recovery features. With your explicit permission, we access:

  • Heart rate data - Read from Apple Watch during workouts to calculate recovery percentage and determine when you are ready for your next set
  • Active and basal energy - Read to display calorie data during and after workouts
  • Resting heart rate - Read to calculate personalized recovery targets
  • Workout data - Written to Apple Health after completed workouts to track your training alongside other fitness data

Important: All HealthKit data is processed entirely on your device. We never transmit, upload, or store your health data on any external server. We do not sell, share, or use your health data for advertising or marketing purposes. This data is used solely to provide the app's core functionality.

1.2 Session Data

Rekur stores records of your workout sessions locally on your device, including:

  • Session duration and date
  • Training goal selected (hypertrophy, strength, endurance)
  • Recovery metrics (recovery percentage, rest interval durations, heart rate data during rest)
  • Per-set breakdown (peak HR, HR decline, time to ready)
  • Self-reported mood after sessions (optional)

This data is stored in your device's local storage (UserDefaults) and is not transmitted to any external server.

1.3 Device-to-Device Data (WatchConnectivity)

If you use Rekur on both iPhone and Apple Watch, session data and workout state are synchronized between your devices using Apple's WatchConnectivity framework. This communication occurs directly between your paired devices and does not pass through any external servers.

Data synchronized includes:

  • Real-time heart rate updates during workouts
  • Workout start/end events and rest transitions
  • Completed session records
  • Premium subscription status

1.4 Purchase Information

Rekur uses Apple's StoreKit framework for in-app purchases and subscriptions. All purchase transactions are processed by Apple. We do not collect, store, or have access to your payment information (credit card numbers, billing address, etc.). We only store a local record of your subscription status to unlock premium features.

2. Information We Do Not Collect

Rekur does not collect:

  • Your name, email address, or account information (no account required)
  • Location data
  • Device identifiers or advertising IDs
  • Usage analytics or crash reports sent to our servers
  • Any data for advertising, tracking, or profiling purposes

Rekur has no user accounts, no cloud storage, no analytics SDKs, and no third-party tracking.

3. How We Use Your Information

All data collected by Rekur is used exclusively to:

  • Provide real-time heart rate-guided recovery during workouts
  • Display workout history and recovery trends
  • Calculate and display recovery analytics (HR decline rate, time to ready, efficiency scoring)
  • Synchronize workout state between your iPhone and Apple Watch
  • Save completed workouts to Apple Health (with your permission)
  • Manage your premium subscription status

4. Data Storage and Security

All your data is stored locally on your device using Apple's standard storage mechanisms (UserDefaults). Data synchronized between iPhone and Apple Watch uses Apple's encrypted WatchConnectivity framework.

We do not operate any servers. Your data never leaves your devices.

If you delete the app, all locally stored data is permanently removed from that device.

5. Apple HealthKit Compliance

In accordance with Apple's HealthKit guidelines:

  • We do not use HealthKit data for advertising or similar services
  • We do not disclose HealthKit data to third parties
  • We do not sell HealthKit data
  • We do not use HealthKit data for purposes unrelated to providing health and fitness functionality
  • HealthKit data is not stored in iCloud or any remote server

6. Third-Party Services

Rekur uses the following Apple frameworks, which are governed by Apple's Privacy Policy:

  • HealthKit - For reading heart rate data and writing workout records
  • StoreKit - For processing in-app purchases and subscriptions
  • WatchConnectivity - For iPhone-Watch data synchronization

We do not integrate any third-party analytics, advertising, or tracking services.

7. Children's Privacy

Rekur is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us so we can delete it.

8. Your Rights

8.1 Data Access and Deletion

Since all data is stored locally on your device, you have full control:

  • Access: All your data is visible within the app (workout history, recovery analytics)
  • Delete: You can delete individual sessions within the app, or delete the app entirely to remove all data
  • HealthKit: You can manage Rekur's HealthKit permissions at any time in Settings > Health > Data Access & Devices > Rekur

8.2 GDPR (European Users)

For users in the European Economic Area: Rekur processes data locally on your device. We do not transfer any personal data to servers or third parties. Since no personal data leaves your device, there is no data controller or processor in the traditional sense. You retain full control over your data at all times.

8.3 CCPA (California Users)

For California residents: Rekur does not sell your personal information. We do not share your personal information with third parties for their direct marketing purposes. Since all data is stored locally and we have no user accounts, there is no personal information to request, delete, or opt out of selling.

9. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected by updating the "Last updated" date at the top of this page. We encourage you to review this page periodically.
