Who we are
This policy describes the public website at https://www.chunhuizk.com operated by Zhejiang Chunhui Intelligent Control Co., Ltd. (春晖智控, Chunhui Controls, chunhuizk), 288 Chunhui Gongye Avenue, Shangyu, Zhejiang, China. Contact: contact@chunhuizk.com or +86-575-82158555.
The site is a product and company information site. It is not a consumer social network and does not require an account for catalog browsing.
Information we collect
When you browse, we and our processors may collect technical data such as IP address, user-agent, language, and pages viewed. Analytics: a self-hosted Plausible instance at analytics.granddongshan.com (cookieless page views). Advertising measurement: Google Ads gtag (AW-18195576629). Session analytics: Microsoft Clarity.
When you submit a contact, product, integrity, or anonymous form, we collect the fields you enter (name, company, email, phone, message, product context). Those submissions are sent to Chunhui backends including general-service.chunhuizk.com and related form endpoints so staff can reply.
Language preference may be stored in the browser (localStorage) so the site can remember locale. Login, if used by employees, is a separate identity flow and is not required for public pages.
Why we use the information
We use the data to operate and secure the site, understand which catalog pages are useful, measure advertising that you may have clicked, and answer inquiries you send us. We do not sell personal information. We do not use public catalog pages as a source of payment-card data.
Legal bases under typical privacy regimes include legitimate interests in running a B2B website and performing a contract or requested communication when you submit a form. Visitors in mainland China are also covered by applicable personal-information protection rules; you may request access or deletion of form submissions by emailing contact@chunhuizk.com.
Cookies, retention, and your choices
Google Ads and Microsoft Clarity may set cookies or similar identifiers. You can block cookies in your browser; core catalog pages still work. Analytics page-view data is kept for operational reporting. Form records are kept as needed to handle the inquiry and for compliance archives.
Crawler permissions for training versus retrieval are published in /robots.txt, /ai.txt, and /llms.txt. This privacy page is the human-readable counterpart for personal data.
