1. Introduction

At Cplus Concept Company Limited ("we," "us," or "our"), we redefine intelligent spatial management through our innovative products: Silent Space, Food Locker, Vending Machine, and Lending System. This Privacy Policy explains how we collect, use, and protect your data—ensuring transparency as precise as our engineering.

2. Data Collection

2.1 Product-Specific Data

• Silent Space:
  ▶ Acoustic fingerprints, noise reduction metrics (dB logs), and motion sensor data.
  ▶ Customized sound profiles for personalized noise cancellation.

• Food Locker:
  ▶ Dual-spectrum scans for ingredient recognition, freshness scores, and temperature/humidity logs.
  ▶ User-defined meal preservation settings.

• Vending Machine:
  ▶ Gesture interaction patterns, purchase history, and nutritional preference analytics.
  ▶ Anonymous demographic inferences from transaction timestamps.

• Lending System:
  ▶ Blockchain-verified asset usage trails, dynamic credit scores, and biometric verification logs (e.g., facial recognition).

2.2 Direct User Input

• Account registration details (name, email, phone number).

• Payment information (encrypted via PCI-DSS compliant gateways).

• Feedback submissions through in-device interfaces.

3. Purpose of Data Processing

• Silent Space: Optimize noise-canceling algorithms using ambient sound analytics.

• Food Locker: Predict shelf life via AI-driven decay modeling and adjust vacuum-cooling cycles.

• Vending Machine: Personalize product recommendations through machine learning.

• Lending System: Calculate trust scores for asset borrowing and prevent fraud via behavioral biometrics.

4. Data Sharing & Security

4.1 Third-Party Partners

• Share anonymized Vending Machine gesture data with UX research firms.

• Transmit Food Locker freshness metrics to cloud providers (AWS IoT Core) for real-time monitoring.

• Disclose Lending System transaction records under legal warrants or regulatory requests.

4.2 Protection Measures

• AES-256 Encryption: Applied to biometric data in Lending System.

• Edge Computing: Process Silent Space audio analytics locally to minimize data exposure.

• Zero-Knowledge Proofs: Verify user age without storing birthdates in Vending Machine.

5. Your Rights & Controls

5.1 Access & Deletion

• Download Food Locker usage histories (CSV/JSON format) via the [Customer Portal].

• Request permanent deletion of Silent Space acoustic profiles.

• Opt out of Vending Machine behavioral tracking while retaining basic functions.

5.2 Consent Management

• Adjust Lending System credit assessment preferences in account settings.

• Enable/disable Food Locker ingredient scanning for dietary customization.

6. International Data Transfers

• EU/UK data stored in GDPR-compliant Frankfurt AWS servers.

• APAC user data hosted in ISO 27001-certified Singaporean facilities.

7. Children’s Privacy

• Age Gates: Vending Machine uses voice analysis to estimate user age (error margin <2%).

• Parental Controls: Restrict Lending System access for users under 18 via family accounts.

8. Policy Updates & Contact

• Version Tracking: Highlight changes to Silent Space data clauses in interactive timelines.
