Privacy Policy

This website is operated by Qingdao Hengweida Trading Co., Ltd. It presents company, product, and sourcing information for business buyers.

The contact form collects name, email, and a message. These records are stored so the company can respond. They are not sold.

The optional customer-service chat sends your questions to a language model provider (DeepSeek) through our server so we can answer product questions. Do not send passwords or unnecessary personal data in chat.

The hosting provider may process technical logs such as IP address, browser type, and requested URL as part of operating the site.

Inquiry records are stored on the website server. Chat answers are generated using DeepSeek when that service is configured. API keys stay in server environment variables.
