Scope
This policy applies to this website and contact made through the listed phone number or email. Project-specific confidentiality, access, storage and deletion rules are governed by separately agreed project documents.
Website access data
Hosting and network providers may process IP addresses, request times, pages, browser and device information, and error logs for security, diagnostics and traffic measurement. The site currently has no user accounts or online inquiry form.
Contact and project data
When you contact us, we may process names, organizations, contact details, project descriptions and files you choose to provide. Do not send confidential or restricted information before confirming a transfer method.
Purposes
Information is used to respond, assess scope, arrange technical discussions, perform agreed services, maintain security and resolve disputes.
Retention and security
Information is retained for a reasonable period needed for communication, project work, financial records or disputes. Access, transfer and storage can be agreed according to sensitivity, but no network transfer is absolutely secure.
Providers and distributed work
Hosting, email, file-transfer or collaboration providers may process data under their service terms. Projects requiring a specific storage region or private environment should raise that requirement before transfer.
Your choices
Contact 540951254@qq.com to ask about, correct or request deletion of information you supplied and that we still retain. Records required by law or an effective agreement may need to remain.
Updates
This policy may change as website functions or service workflows change. The date shown on this page identifies the current version.
