Privacy Notice

Last updated 5 November 2026

YUCHANG LLC operates yuchang.us and is responsible for the personal information collected through this website. You can contact us at [email protected] about your information or a website review request.

Information you provide

When you request a website review, we collect your name, email address, website URL, country or region, the details you enter about your project, your consent, and the time of submission. Please share business-related information and keep passwords, payment details, and sensitive personal information out of the form.

How we use it

We use your information to review your website, reply to your request, discuss a possible project, and maintain a record of that conversation. We also use limited technical information to keep the site secure and prevent automated abuse. Where data-protection law requires a legal basis, we rely on steps you request before entering a contract, our legitimate interest in operating a secure business website, and consent where applicable.

Hosting and service providers

The website and enquiry records are hosted on a server in Singapore. Cloudflare handles website traffic and notification email delivery. Enquiry notifications are delivered to our Gmail inbox, operated by Google. These providers process information needed to provide their services. Our operator works remotely, including from China, and information may be processed in Singapore, the United States, and other countries where our providers operate. Contact us if you need information about a particular processing location before submitting a request.

How long we keep information

We keep enquiry information for the time needed to respond, assess the proposed project, and manage any resulting business relationship. The relevant period depends on whether discussions are active, whether you become a client, and any accounting, legal, or dispute-resolution requirements. You can ask us to delete an enquiry when it is no longer needed.

Cookies and technical data

Our application uses no advertising or analytics cookies. Our hosting and security providers may process IP addresses, request times, and browser information to deliver and protect the website. The form uses a random submission reference to handle retries safely.

Your choices

Depending on where you live and which laws apply, you may request access, correction, deletion, a copy of your information, or limits on processing, and you may object to certain uses. You can withdraw consent for future contact by emailing us. Where applicable, you can also complain to your local data-protection authority. We may ask for information to verify that a request relates to you.

Updates and contact

We will update this notice if our handling of information changes. For privacy requests, email [email protected] with the subject “Privacy request”.
