Privacy Notice
How enquiry information is handled on this website.
Who operates this website
Liangshan Chenghang Machinery Equipment Co., Ltd., Liangshan, Shandong, China. Contact sales@chenghang.com with privacy or equipment questions.
Information you provide
We store the contact information, company details, equipment requirements and optional files you submit so our team can respond to your enquiry. Only share information you are authorised to provide.
Storage and access
Enquiries are stored on our website server. Access is limited to authorised administrators and assigned sales users. Attachments stay outside the public website directory. Images are re-encoded; PDFs remain quarantined pending security review.
Email and external services
Automatic enquiry emails are not currently enabled. Your enquiry is saved in our private administration area for staff to review and respond directly. Queued email records do not mean a message has been sent. We do not currently enable advertising analytics, marketing subscriptions or an external CRM connection.
Retention and requests
Submitted records remain in the private enquiry system until an authorised administrator deletes them. Contact sales@chenghang.com to request access, correction or deletion. Some records may need to be retained for an order or an applicable obligation; our team will explain any restriction when responding.
Website security
The web server records technical request information to operate and protect the site. The enquiry form uses a short-lived request token and rate limits. Do not submit highly sensitive personal information.
