Privacy Policy

When you visit public pages, servers may record basic logs such as access time, path, IP address, browser or crawler user agent, HTTP status code and similar operational data for site operation, security troubleshooting and service-quality analysis.

When you contact us by phone, form, email or other public channels, we may process the name, organization, contact details, cooperation needs, submissions or feedback that you provide.

For authorized CMS users, the system may process account, session, uploaded-file and operation records to maintain CMS security and auditability.

We use relevant information to respond to enquiries, support business cooperation, handle submissions and copyright feedback, maintain site security, investigate abnormal access and improve public content and services.

We do not sell visitors’ personal information unless required by law, authorized by you, or necessary to complete a requested service.

Current public content pages do not set cookies for advertising tracking. CMS administration, login sessions, security protection or necessary site functions may use cookies or similar technologies.

Browsers, CDN/hosting services or third-party linked sites may process cookies or access logs under their own rules. You can manage cookies through your browser settings.

The site may link to CALI, Ming Classroom, Agricultural Lighting Network, partner organizations, event platforms and other external websites. Please review their privacy policies when visiting them; China Light does not control third-party data practices.

For hosting, database, file storage, security protection and operations, we may use necessary infrastructure providers and process relevant data only to the extent required for those services.

We retain relevant information for as long as needed for the purposes above, and delete, anonymize or archive it according to operational, security, audit or legal requirements.

We use reasonable technical and administrative measures to protect information, but internet transmission and storage cannot be guaranteed to be absolutely secure.

If you need to access, correct or delete information you submitted, or if you have questions about this policy, contact us through China Light’s public contact channels. We will process requests according to law after verifying identity and request scope.

If you do not agree with this policy, you may stop using functions that submit information. Public browsing may still generate necessary server access logs.

We may update this policy according to site functions, laws or operational needs. The updated effective date will be shown on this page.
