DutyRefund ("we," "our," or "us") is a service of IntelliNexa AI Limited, a Hong Kong company (CRN: A5151 7957). This Privacy Policy describes how we collect, use, and safeguard information when you visit our website at dutyrefund.net or use our services.

1. Information We Collect

1.1 Information You Provide

When you contact us via our contact form or email, we may collect:

• Your name
• Your email address
• Your company name
• The content of your message or inquiry

1.2 Demo Tools

Our Quick Estimator tool does not collect or store any input data. All calculations are performed in your browser using client-side JavaScript.

Our Demo ES-003 Analysis tool processes uploaded CSV files in memory only. Uploaded files are parsed for the purpose of generating analysis results and are never stored on our servers. Once the analysis is complete and results are returned, the uploaded data is discarded from memory.

1.3 Automatically Collected Information

Like most websites, we may collect standard web server log information including IP addresses, browser type, referring pages, and timestamps. This data is used solely for operational monitoring and is not linked to any personally identifiable information.

2. How We Use Your Information

We use the information we collect to:

• Respond to your inquiries and provide requested information
• Deliver our services as agreed in our engagement letters
• Improve our website and services

We do not sell, trade, or rent your personal information to third parties. We may share information:

• With your explicit written consent
• As required by applicable law or legal process
• With service providers who assist in operating our website (e.g., hosting, email delivery), subject to confidentiality obligations

4. Data Security

We implement appropriate technical and organizational measures to protect your information. For client engagements, we sign a mutual Non-Disclosure Agreement (NDA) before reviewing any entry data. Your trade data is processed in secure environments and is never shared without written authorization.

5. Cookies

Our website uses minimal cookies, if any. We do not use tracking cookies, advertising cookies, or third-party analytics services that set cookies on your device. Any cookies used are strictly necessary for the functioning of the website.

6. Third-Party Services

Our contact form may use FormSubmit for email delivery. Please refer to FormSubmit's privacy policy for information on how they process form submissions. We use Google Fonts to serve the Inter typeface — Google may collect usage data as described in their privacy policy.

7. Data Retention

We retain contact form submissions and email correspondence for as long as necessary to fulfill the purposes described in this policy, or as required by law. Demo tool data is not retained.

8. Your Rights

Depending on your jurisdiction, you may have rights regarding your personal information, including the right to access, correct, or delete your data. To exercise these rights, contact us at hello@dutyrefund.net.
