Privacy Policy

Health Stamp

Last Updated: January 24, 2026

Introduction

Health Stamp ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle your information when you use the Health Stamp app for iOS and watchOS.

The short version: Your data stays on your device. We don't collect, store, or transmit any of your personal information, health data, or photos.

Information We Do NOT Collect

Health Stamp is designed with privacy as a core principle. We do not collect, store, or have access to:

  • Health Data – Your steps, distance, cycling, swimming, rowing, or any other HealthKit data
  • Photos or Videos – Your photo library content remains entirely on your device
  • Location Data – We do not access or track your location
  • Personal Information – No names, email addresses, or account information
  • Usage Analytics – We do not track how you use the app
  • Device Identifiers – We do not collect device IDs or fingerprints

How Health Stamp Works

Health Data Access

Health Stamp requests read-only access to your HealthKit data to generate activity captions for your photos. This data is:

  • Read directly from Apple HealthKit on your device
  • Used only to generate caption text
  • Never transmitted off your device
  • Never stored by us

You control which health data types Health Stamp can access through iOS Settings > Privacy & Security > Health > Health Stamp.

Photo Library Access

Health Stamp requests access to your photo library to:

  • Read photos taken on selected dates
  • Write caption metadata (IPTC) to photos
  • Create stamped copies of your photos

All photo processing happens locally on your device. Your photos are never uploaded to any server.

Watch Connectivity

If you use the Apple Watch companion app, it communicates directly with your iPhone using Apple's WatchConnectivity framework. This communication:

  • Stays between your devices
  • Is encrypted by Apple's frameworks
  • Does not pass through any external servers

Subscriptions

Health Stamp offers an optional subscription for premium features. Subscriptions are processed entirely through Apple's App Store. We do not:

  • Have access to your payment information
  • Store any billing details
  • Know your Apple ID or email address

Apple handles all subscription management. See Apple's Privacy Policy for details.

Third-Party Services

Health Stamp does not integrate with any third-party analytics, advertising, or tracking services. The only external service used is:

  • Apple App Store – For subscription processing (managed by Apple)

Data Storage

All app data is stored locally on your device using:

  • UserDefaults – For app settings and preferences
  • Photo Library – For stamped photos and metadata

We do not operate any servers or cloud storage for user data.

Children's Privacy

Health Stamp does not knowingly collect information from children under 13. Since we don't collect any personal information from any users, there is no age-restricted data collection.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by updating the "Last Updated" date at the top of this policy.

Your Rights

Since we don't collect your data, there is no personal data to access, correct, or delete from our systems. All your data remains on your device and can be managed through:

  • iOS Settings – Manage app permissions
  • Photos App – View and delete stamped photos
  • App Deletion – Removing the app removes all local settings

Medical Disclaimer

Health Stamp is not a medical device and does not provide medical advice, diagnosis, or treatment. All health and activity data displayed — including steps, distance, and calorie figures — is for informational and personal use only. This app should not be used to make medical or health decisions. Always consult your physician or qualified healthcare provider with any questions regarding a medical condition or fitness program.
