Privacy Notice

Who is responsible for the data

Yucheng Machinery Technology Co., Ltd. (YUCHENG HARVEST) operates this website from Diankou, Zhuji, Zhejiang, China. The company is responsible for business information submitted through this website.

Information we collect

We collect only the information needed to review a business inquiry, prepare a quotation, secure the website and understand whether our pages are useful.

• Company, contact name, business email, country and buyer type
• Machine, part reference, quantity, dimensions, destination and commercial requirements
• Files that you choose to attach, such as product photos, PDFs or purchase lists
• Limited technical information such as page URL, referral source, consent choice and security logs
• Advertising attribution parameters such as GCLID or UTM values when present

Why we use the information

Inquiry data is used to identify the requested part, assess fitment evidence, prepare and follow up a quotation, maintain an order record, prevent misuse and meet applicable legal obligations.

Optional analytics and advertising measurement are used only according to the visitor's consent choice and must not receive inquiry names, email addresses, free-text messages or attachment content.

Sharing and international processing

Information may be shared with service providers or manufacturing partners only when necessary to host the website, protect the form, review the requested product, store private files, deliver business email or prepare the quotation. These parties should receive only the information required for their role.

Because the company and its service providers may operate in different countries, information may be processed outside the visitor's country. Appropriate contractual and technical safeguards should be used where required.

Retention and security

Inquiry records are retained only for the quotation, order history, fraud prevention and legal periods reasonably required for the business relationship. Records that are no longer required should be deleted or anonymized.

Technical attachments must be stored privately with access control. No internet transmission or storage system can be guaranteed completely secure, so do not upload confidential information that is not needed for the inquiry.

Your choices and requests

Depending on applicable law, you may request access, correction, deletion or restriction of your personal information, or object to certain processing. You may also reject optional analytics and advertising storage without losing access to essential website functions.

Submit a privacy request through the contact page and identify the business email used in the inquiry so the request can be verified.
