Information you send us
When you submit an enquiry, Shenzhen Chengyue Energy Co., Ltd. receives the contact details and project information you enter. We use this information to evaluate your request, respond and coordinate the related business discussion. Please do not include unnecessary sensitive personal information.
Website statistics and logs
The website records aggregated page views by date, page group and language to understand usage. These page-view statistics do not store IP addresses or persistent visitor identifiers. Server security and operational logs may contain IP addresses and request details and are retained under the server’s log rotation settings.
Enquiry source information
If you submit an enquiry, its entry page, referring website hostname and available campaign tags may be included to help us understand the enquiry source. We exclude full referrer URLs, advertising click IDs and persistent visitor identifiers. This context is held in page memory and saved only with your enquiry.
Cookies and local preferences
Language is determined by the page URL, without a language-preference cookie. The public website does not add advertising trackers or third-party analytics scripts. Browser and network infrastructure may still maintain technical state needed to serve the website.
Browsers used to access our authenticated administration system receive a preference cookie that excludes subsequent visits from page-view statistics. This cookie lasts up to one year and contains only an internal-visit flag, not an account ID or unique visitor identifier.
Access and retention
Enquiries are stored in the website’s database and are accessible through the authenticated administration system. Information is kept for the related business follow-up and operational needs. Contact us to request correction or deletion of information you submitted.
