Privacy Policy for SkinHealthMonitor

Last Updated: February 21, 2026 | Effective Date: February 21, 2026

Welcome to SkinHealthMonitor. We are committed to protecting your privacy, especially given the sensitive health-related nature of this application. This Privacy Policy explains what information we collect, how we use it, and your rights regarding your data.

By using SkinHealthMonitor, you agree to the collection and use of information in accordance with this policy.

1. Information We Collect

1.1 Data Stored Locally on Your Device

SkinHealthMonitor stores all data locally on your Android device. We do NOT collect, transmit, or store any of your data on external servers. The following data is stored in a local database:

Skin Lesion Data

• Lesion names, notes, and body zone locations you define
• Photos of skin lesions captured through the app
• ABCDE assessment scores and results
• Photo comparison analysis results
• Dates and timestamps of photos and assessments

App Preferences

• Reminder schedules for skin check-ups
• Display preferences (theme, disclaimers)
• Onboarding completion status

1.2 Android System Permissions

To function properly, SkinHealthMonitor requires the following Android system permission:

Camera Permission

• Purpose: Capture photos of skin lesions for tracking over time
• What it accesses: Device camera hardware only
• Data storage: Photos are saved to app-private internal storage, not to the device gallery
• Why it's essential: Photo capture is the core function for monitoring skin changes

Important: The camera permission is used ONLY to capture photos within the app. We do not access your existing photos or gallery, record video, use the camera in the background, or share photos with any external service.

2. How We Use Your Data

All data processing happens entirely on your device. We use your data to:

• Track lesion history – Store and display photos of skin lesions over time
• Provide ABCDE assessments – Guide you through the ABCDE criteria for skin lesion evaluation
• Compare photos – Analyze brightness, color, and contrast changes between photos using on-device processing
• Send reminders – Notify you about scheduled skin check-ups
• Remember preferences – Store theme settings and app configuration

We do NOT:

• Share your data with third parties
• Use your data for advertising
• Sell your data to anyone
• Upload your photos or health data to cloud servers
• Use analytics or tracking services
• Perform any remote AI or cloud-based analysis

3. Data Storage and Security

3.1 Local Storage Only

All data is stored in a local SQLite database on your device using Android's Room persistence library. Photos are stored in the app's private internal storage. The database and photos are accessible only by SkinHealthMonitor (sandboxed by Android OS), deleted if you uninstall the app, and not backed up to cloud services by default.

3.2 Security Measures

• Data is stored in Android's secure app sandbox
• Photos are saved to app-private storage (not accessible to other apps)
• No network transmission of personal or health data
• No external API calls that expose user data
• On-device TensorFlow Lite processing – no cloud inference

3.3 Data Retention

• Indefinitely while the app is installed
• Deleted automatically when you uninstall SkinHealthMonitor
• Can be manually cleared via Settings → Data & Privacy → Delete All Data

4. Health Data Disclaimer

SkinHealthMonitor is a tracking and self-monitoring tool only. It does NOT provide medical diagnosis, replace professional dermatological examination, use clinically validated AI models, or make treatment recommendations.

The ABCDE assessment and photo comparison features are informational aids to help you notice changes. Always consult a qualified dermatologist for medical advice regarding skin lesions.

5. Third-Party Services

SkinHealthMonitor does NOT use any third-party services, analytics, or SDKs. We do not integrate Google Analytics, Firebase Analytics, advertising networks, crash reporting services, cloud AI services, or social media SDKs. The app is completely standalone and operates entirely offline after installation.

6. Children's Privacy

SkinHealthMonitor does not knowingly collect data from children under 13 years old. The app is designed for general audiences (13+), does not require account creation, and does not collect personally identifiable information.

7. Your Rights and Choices

7.1 Access Your Data

All data is visible within the app (lesion history, photos, assessments, settings). No hidden data collection.

7.2 Delete Your Data

• Option 1: Settings → Data & Privacy → Delete All Data
• Option 2: Delete individual lesions or photos from the lesion detail screen
• Option 3: Uninstalling SkinHealthMonitor (removes all data permanently)

7.3 Control Permissions

You can revoke camera permission at any time via Android Settings → Apps → SkinHealthMonitor → Permissions. Note: Revoking camera permission will prevent you from taking new photos.

8. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Changes will be reflected in the "Last Updated" date at the top. Your continued use of SkinHealthMonitor after changes constitutes acceptance of the updated policy.

9. Legal Compliance

GDPR (EU General Data Protection Regulation)

• Lawful basis: Legitimate interest (app functionality)
• Data minimization: We collect only what's necessary for skin tracking
• Purpose limitation: Data used only for stated purposes
• Storage limitation: Data deleted on uninstall
• Special category data: Health-related data is processed locally only, never transmitted

CCPA (California Consumer Privacy Act)
