Privacy Policy

Our Privacy Commitment

Health Scan Express is designed with your privacy as our top priority. We believe your health information is deeply personal and should remain under your control.

How Your Health Data Is Handled

When You Scan a Device

1. You take a photo: The image is captured on your iPhone and temporarily stored in the app's memory.
2. Secure transmission: The image is sent over an encrypted HTTPS connection to our service for processing.
3. AI processing: The image is analyzed by AI to extract the text readings from your device display (e.g., blood pressure, weight).
4. Immediate deletion: Once the readings are extracted, the image is immediately deleted from our servers. It exists only during the brief processing time.
5. Data returned to you: Only the extracted readings (numbers and measurements) are sent back to your iPhone.

Third-Party AI Processing

To read the numbers from your health device displays, Health Scan Express uses third-party artificial intelligence (AI) vision services to analyze and extract measurements from device images.

What This Means for You

• Images are sent to AI service providers: Your device photos are temporarily processed by third-party AI services to extract the readings.
• Third-party privacy policies apply: The AI service providers we use have their own privacy policies governing how they process data. We strongly encourage you to review their policies:
  • OpenRouter Privacy Policy - AI routing and processing service we use for image analysis
• Data processing by third parties: OpenRouter may process your images through various AI model providers. Please review their privacy policy to understand how your data is handled by their service.
• By using Health Scan Express, you acknowledge that your device images will be processed by third-party AI services for the purpose of extracting health measurements.

What Data We Collect

Data We DO Collect

• Subscription status: We verify your active subscription to enable app features
• Device type detected: We log which type of device was scanned (e.g., "blood pressure monitor" or "digital scale")
• Technical information: Error logs, response times, and system performance data to improve the service

Data We DO NOT Collect

• Your actual health readings: The numbers from your scans (blood pressure, weight, etc.) are not logged or stored on our servers
• Device images: Photos are deleted immediately after processing
• Personal information: We don't collect your name, email, or other identifying information through the app
• Location data: We don't track where you are or where scans are taken
• IP addresses: We don't log or store your IP address

Apple Health Integration

Health Scan Express can integrate with Apple Health to store your health measurements on your device.

Health Data Permissions

• When you enable Apple Health sync, the app requests permission to write health data (blood pressure, weight, etc.)
• You control which data types the app can access through iOS Settings
• You can revoke these permissions at any time in your iPhone's Settings app
• Data written to Apple Health is controlled by Apple's privacy policies, not ours

Data Security

We implement industry-standard security measures to protect your data:

• HTTPS encryption: All data transmitted between your iPhone and our servers uses TLS 1.2+ encryption
• Subscription-based access: Only active subscribers can use the scanning service
• Input validation: All data is validated to prevent malicious input
• Rate limiting: Protection against abuse and unauthorized access
• No database storage: Since we don't store health data, there's no database of personal health information that could be compromised

Data Retention

Health images and readings: Zero retention. All images are deleted immediately after processing, and actual health measurements are never stored.

System logs: Anonymized technical logs (error messages, device types detected, performance metrics) may be retained for up to 30 days for debugging and service improvement purposes. These logs contain no personal health information.

Your Privacy Rights

Right to Be Forgotten

Since we don't store your health data, there's no personal data to delete. If you cancel your subscription, any subscription-related data is removed according to Apple's App Store policies.

Data Portability

All health readings are returned directly to your iPhone. If you enable Apple Health sync, your data is stored locally in the Health app, which you can export at any time through iOS settings.

Right to Object

If you don't consent to third-party AI processing of your health device images, you should not use Health Scan Express, as AI processing is essential to the app's functionality.

Children's Privacy

Health Scan Express is not intended for use by children under 13 years of age. We do not knowingly collect personal information from children under 13.

Changes to This Privacy Policy

We may update this privacy policy from time to time. When we do, we will revise the "Last Updated" date at the top of this page. We encourage you to review this policy periodically.

Material changes will be communicated through the app or via the email associated with your App Store account.
