Junsoft ("we", "our", or "us") operates the DreamTune AI mobile application (the "App"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our App.

1. Information We Collect

1.1 Health Data

With your explicit permission, the App accesses Apple HealthKit data including:

• Sleep analysis (bedtime, wake time, sleep stages)
• Heart rate and heart rate variability (HRV)
• Respiratory rate

This data is used solely to provide personalized sleep analysis and recommendations. We do not sell, share, or use your health data for advertising purposes.

1.2 Account Information

When you sign in with Apple, we receive:

• A unique user identifier

• Deliver CBT-I (Cognitive Behavioral Therapy for Insomnia) programs
• Sync your data across devices (for subscribers)
• Improve our AI models and algorithms

3. Data Storage and Security

Your sleep data is stored locally on your device using Apple's SwiftData framework. If you subscribe and enable cloud sync, data is encrypted in transit (TLS 1.3) and at rest on our servers hosted on Amazon Web Services (AWS) in the Asia Pacific (Seoul) region.

4. Data Sharing

We do not sell or share your personal data with third parties. We may share anonymized, aggregated data for research purposes. We may disclose information if required by law.
