Privacy Policy

1. Introduction

This Privacy Policy explains how we collect, use, store and protect your personal data when you use our AQL Inspector offline sampling calculator web application (“Service”). This policy complies with GDPR and Hong Kong SAR data protection regulations.

2. Data We Collect

2.2 Automatically Collected Data

• Browser type, device model, access timestamp
• Offline cached local storage data for your calculation records (stored only on your device)

2.3 Local Offline Data

All your sampling calculation results are saved locally on your browser via Service Worker cache. We cannot access or read these offline records remotely.

3. How We Use Your Data

• Respond to customer support inquiries
• Fix technical errors and improve app functionality
• Comply with legal tax and accounting requirements

We will never sell, rent or share your personal information to third parties for marketing purposes.

4. Data Storage & Security

User account data is stored on secure encrypted servers. All offline calculation data remains isolated in your local browser cache. We implement HTTPS encryption to protect all data transmission between your device and our server.

5. Your User Rights (GDPR)

• Right to correct inaccurate personal information
• Right to delete your account and all associated server data

6. Cookies & Local Storage

We use browser local storage and Service Worker cache only to enable offline PWA functionality. No tracking cookies are deployed for advertising.

7. Third-Party Services

Our payment processing is handled by Creem. Their separate privacy policy governs all payment data. We have no control over their data handling practices.

8. Data Retention

Account and payment records are retained for 7 years to meet tax compliance rules. Local offline calculation data stays on your device until you clear browser cache manually.

9. Policy Updates

We may revise this privacy policy at any time. Updates will be published on this page with a new revision date. Continued use of the Service after updates counts as acceptance of the revised policy.
