Privacy Policy for Neck Pain Relief Game

Last Updated: April 17, 2026

1. Introduction

Shenzhen Fu Kang Heng Development Co., Ltd. ("we," "our," or "us") operates the Neck Pain Relief Game mobile application (the "App"). This Privacy Policy explains how we handle information when you use our App.

Neck Pain Relief Game is designed to help users relieve neck pain and improve cervical mobility through head-movement gameplay powered by Apple's ARKit face tracking technology. We are strongly committed to protecting your privacy. The App is built on a privacy-first principle: all processing happens on your device and nothing is ever sent to us or any third party.

2. Information We Collect

2.1 Information We DO NOT Collect

Neck Pain Relief Game is designed with your privacy in mind. We do not collect, store, or transmit any of the following:

• Personal identification information (name, email, phone number)
• Camera images, video, or facial images of any kind
• Biometric or facial recognition data
• Health or medical data uploaded to external servers
• Usage data or app activity tracking
• Device information or identifiers
• Location data
• Any other personal data sent outside your device

2.2 Information Collected by Apple

When you download the App from the Apple App Store, Apple may collect certain information as described in Apple's Privacy Policy. This includes:

• App download data
• Crash reports (if you opt-in to share with Apple)

We do not have access to this information. Please refer to Apple's Privacy Policy for details on how Apple handles your data.

3. How the App Works Locally

All functionality in Neck Pain Relief Game operates entirely on your device:

• Face Tracking: The App uses Apple's ARKit framework to track your head movements in real time via the front-facing TrueDepth camera. This tracking is used solely to control the in-game cheetah character. No camera images, video frames, or facial geometry data are stored or transmitted at any time.
• Head Movement Processing: All head orientation calculations (pitch, yaw, roll) are computed locally on your device by Apple's ARKit. The App only reads the resulting numeric values to move the game character — it never accesses raw camera data directly.
• Session History: Game session records (date, score, duration, difficulty, and neck movement range statistics) are stored locally in the App's database on your device only. This data is never uploaded or shared.
• Movement Heatmap: After each session, the App generates a visual map of your neck movement range from data collected during that session. This data is stored locally and is never transmitted.
• Settings & Preferences: Your calibration settings and app preferences are saved locally on your device only.
• Audio: The App plays background music and sound effects stored within the App bundle. It does not access your microphone or your device's music library.
• No Internet Required: The App functions completely offline and does not communicate with any servers.

4. Camera and Face Tracking

The App requires access to your device's front-facing TrueDepth camera solely to enable ARKit face tracking for gameplay. We want to be transparent about how this works:

• The camera is only active while a game session is in progress
• No photos, videos, or facial images are captured or saved
• No facial recognition or biometric identification is performed
• Apple's ARKit processes the camera feed on-device and provides only head orientation angles (numeric values) to the App
• You can revoke camera permission at any time in iOS Settings → Privacy & Security → Camera. Note that the App requires camera access to function.

5. Third-Party Services

Neck Pain Relief Game does not integrate with any third-party analytics, advertising, or tracking services. The App does not contain any third-party SDKs that collect user data. The only framework used for sensor input is Apple's own ARKit, which operates entirely on-device.

6. Children's Privacy

Neck Pain Relief Game is not directed to children under the age of 13. We do not knowingly collect any information from children. The App does not collect any data from any users regardless of age.

7. Data Security

Since Neck Pain Relief Game does not collect, transmit, or store any user data on external servers, there is no risk of data breaches or unauthorized access to your information through our App. All session records and settings remain securely on your device under your complete control.

8. Your Rights and Choices

You have complete control over the App and your data:

• Session History: You can view all past session records within the App at any time.
• All App Data: You can delete all app data by uninstalling the App from your device. Uninstalling removes all locally stored session records, settings, and calibration data.
• Camera Access: You can revoke camera permission at any time in iOS Settings. The App will be unable to run game sessions without camera access, but no previously stored data will be affected.

9. Permissions

Camera Access (Front-Facing TrueDepth Camera)

• Required to enable ARKit face tracking for head-movement gameplay
• Only active during a game session
• No images or video are ever captured, saved, or transmitted
• You can revoke this permission in iOS Settings at any time

10. Health Disclaimer

Neck Pain Relief Game is designed for gentle neck movement and general wellness purposes only. It is not a medical device, is not intended to diagnose or treat any medical condition, and does not replace professional medical advice, diagnosis, or treatment. Users with diagnosed cervical conditions, recent neck injuries, or chronic pain should consult a qualified healthcare professional before using the App.

11. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be reflected by updating the "Last Updated" date at the top of this policy. We encourage you to review this Privacy Policy periodically.

If we make material changes to how we handle user information, we will provide notice through the App or App Store listing.

12. International Users

Neck Pain Relief Game is available globally in English, Chinese, Spanish, Japanese, French, German, and Portuguese. Since the App does not collect or transmit any data, there are no cross-border data transfers or regional privacy considerations.
