DeepHealth Privacy Policy

Effective Date: June 22, 2026

Hong Kong Jiuying Network Technology Co., Ltd ("we", "us", or "our") is committed to protecting the privacy of our users ("you"). This Privacy Policy is meant to explain to you how we collect, use, store, and protect your personal data when you use our application, DeepHealth (the "App").

Please read this Privacy Policy carefully to understand our views and practices regarding your privacy. By using the App, you are agreeing to the terms of this Privacy Policy. This Privacy Policy may change from time to time. If we make any material changes, we will notify you by posting the revised policy within the App or by other appropriate means. Your continued use of the Services after the date any such changes become effective constitutes your acceptance of the new policy.

1. Data We Collect

In order to provide and improve our Services, we may collect the following types of personal data:

1.1 Information You Provide Directly

When you register an account, set up your profile, or use specific features of the App, you may provide us with:

•Basic Information: Your name, date of birth, gender, email address, phone number, and account name.

•Health and Physical Data: Your height, weight, heart rate, heart rate variability (HRV), blood pressure, blood oxygen saturation, sleep patterns, activity levels, workout data, mood, stress levels, and other health-related information you voluntarily enter. This data may be provided through manual entry or synced via third-party health devices (e.g., Apple HealthKit) that you choose to connect.

•Account Credentials: If you register or log in through third-party platforms (e.g., Facebook, Apple ID, Google), we may collect certain personal data from those accounts to complete the registration and login process.

1.2 Data Collected Automatically

When you use the App, we may automatically collect:

•Device Information: Device type, model, operating system version, device identifiers (such as IDFA, IDFV), language settings, and time zone.

•Usage Data: Frequency and duration of App use, features accessed, click behavior, App performance data, and crash reports.

•Network Information: IP address (used for approximate geolocation) and network type (Wi-Fi, cellular).

•Technical Data: App version, API keys, sync tokens, and session IDs.

1.3 Information from Third-Party Integrations

If you choose to connect DeepHealth with third-party services (such as Apple HealthKit, Google Health Connect, or other wearables), we may receive your health and activity data with your explicit consent. This may include:

•Vital Signs: Heart rate, HRV, blood pressure, respiratory rate, body temperature, blood oxygen, ECG, etc.

•Physical Metrics: Height, weight, body composition, etc.

•Activity Data: Steps, workouts, distance, calories burned, recovery metrics, etc.

•Sleep Patterns: Duration, stages, and quality metrics.

•Wellness Tracking: Stress levels, energy, mood, habits, and women's health data (e.g., menstrual cycles).

Note: We strongly recommend connecting Apple HealthKit (for iOS) or Google Health Connect (for Android) to enable the App to receive comprehensive, high-quality data for more accurate insights. You can use the App without these integrations, though some core features may be limited.

2. AI Analysis and Processing

DeepHealth includes AI-powered analysis features designed to provide deep wellness insights.

•Data Utilization: Our AI models process your heart rate, HRV, sleep, and activity data to identify health trends, assess stress levels, provide personalized recommendations, or generate health prediction reports.

•Processing Methods:

•Local Processing: Certain AI analyses may be performed directly on your device.

•Cloud Processing: Complex AI analysis may require transmitting de-identified data to our secure servers or authorized third-party AI service providers (e.g., OpenAI).

•Data Security: Data transmitted to AI engines is strictly encrypted. We prohibit third-party AI providers from using your personal data to train their own general models or for any other secondary purposes.

•Non-Medical Disclaimer: All AI-generated analyses and suggestions are for informational purposes only and do not constitute a medical diagnosis or professional medical advice. Always consult a healthcare professional before making health decisions based on AI insights.

•User Control: You can enable or disable specific AI analysis features at any time within the App settings.

3. How We Use Your Data

We use your data primarily for the following purposes:

•To Provide Services: Operating core features like heart rate measurement, data logging, account management, and providing personalized health reports.

•To Improve the App: Analyzing usage patterns to identify improvements, fix bugs, and develop new features.

•To Personalize Experience: Using AI to provide customized content, suggestions, and features based on your health data and preferences.

•For Security and Compliance: Ensuring App security, preventing fraud, and complying with legal requirements.

•Customer Support: Responding to inquiries and resolving technical issues.

•Marketing: With your consent, sending communications about our products, services, and promotions. You may opt out at any time.

4. Who We Share Data With

We do not sell, trade, or rent your personal data to others. We may share data with:

•Service Providers: Third parties that assist us in providing services, such as data analytics, AI services, cloud storage, and customer support. These providers access data only to perform their functions and are contractually bound to our privacy and security requirements.

•Legal Requirements: When required by law or to respond to valid legal processes (e.g., court orders, government requests).

•Business Transfers: In the event of a merger, acquisition, asset sale, or bankruptcy, your data may be transferred as part of the business assets.

•With Your Consent: We may share data with third parties whenever you provide explicit consent.

5. How We Protect Your Data

We use industry-standard physical, procedural, and electronic security measures, including encryption, to protect your personal data from unauthorized access, disclosure, alteration, and destruction. While we strive for absolute security, no method of transmission or electronic storage is 100% secure.

6. Data Retention

We retain your data for as long as needed to provide the Service, for the original purpose of collection, as required by law, or until we receive a request for erasure. After this period, your personal data will be either erased or anonymized for analytical use.

7. Your Data Rights

Depending on applicable laws, you may have the right:

•To access and receive a copy of your personal data.

•To request correction of inaccurate or incomplete data.

•To request erasure of your data (under certain conditions).

•To restrict or object to the processing of your data.

•To data portability in a machine-readable format.

•To withdraw consent at any time where processing is based on consent.

To exercise these rights, please contact us using the details provided below. We may ask you to verify your identity before acting on your request.

8. Protection of Children

We do not knowingly collect personal data from children under 13 (or under 16 in the EEA). If a parent or guardian becomes aware that their child has provided us with data without consent, please contact us immediately, and we will take steps to delete such data.

9. Camera Data Processing

When you use the heart rate measurement feature, the App accesses your device's camera (usually with the flash) to detect blood flow changes in your fingertip using Photoplethysmography (PPG) technology.

•Local Processing: Images or video streams captured by the camera are processed locally on your device to extract heart rate data. Raw image/video data is NOT uploaded to our servers or stored in your device's photo library.

•Data Security: We do not collect or store your camera images/videos for any other purpose. These temporary data are deleted from memory immediately after processing.

•User Control: The App requests explicit authorization for camera access. You can revoke this at any time in your device's system settings.
