Privacy Policy

Last updated: September 7, 2026

This Privacy Policy explains how XISTREE SCIENCE AND TECHNOLOGY (“XISTREE”, “we”, “us”) collects, uses and protects information when you visit our website or engage us for AI and software development services.

1. Information we collect

We may collect contact and business information you provide to us, including your name, company, email address, project requirements and correspondence. For active projects, we may also process information reasonably required to deliver the agreed services. We do not collect payment card details directly; payment processing providers handle that information under their own privacy terms.

2. How we use information

• To respond to inquiries and prepare project proposals.
• To enter into and perform service agreements.
• To issue invoices, maintain business records and meet legal obligations.
• To secure, operate and improve our services.

3. Legal bases and retention

We process information where necessary to respond to your request, perform a contract, comply with law, or pursue our legitimate interest in operating a secure professional-services business. We retain information only as long as needed for these purposes and applicable record-keeping requirements.

4. Sharing and international processing

We may use vetted service providers for hosting, communications, analytics and payment processing. They receive only the information needed to perform their function. Because we serve clients remotely, information may be processed in countries other than your own with appropriate safeguards.

5. Security

We use reasonable administrative and technical measures to protect information. No online system can be guaranteed completely secure, so clients should not send credentials or sensitive datasets by ordinary email.

6. Your choices and rights

Depending on your location, you may request access, correction, deletion, restriction or a copy of your personal information, or object to certain processing. We may need to verify your identity before completing a request.

7. Contact

For privacy questions or requests, email contact@xistree.hk. XISTREE SCIENCE AND TECHNOLOGY is the controller responsible for information described in this policy.
