Privacy policy

Scope of this policy

The SIXUAN DATA website is operated by Nanchang Sixuan Technology Co., Ltd. (南昌思玄科技有限公司), based in Nanchang, Jiangxi, China. This policy describes information handling principles for service pages, case studies, delivery resources and project inquiry forms.

Data sources, permitted uses, confidentiality and processing responsibilities for a specific project are agreed separately in writing. This policy does not replace a project agreement.

Information you provide

The project form includes your name, company, job title, email or phone, service type and project description. You may also add data types, scale, timing and reference materials. Required fields are identified in the form.

Provide only relevant information and make sure you are authorized to share it. An initial inquiry does not require identity documents, passwords, complete personal datasets or unauthorized client information.

Inquiries and reference materials

Project details

Names and contact details identify the people involved. Company, service type and project descriptions help clarify context, scope and the possible approach.

Reference materials

Begin with de-identified field structures, task descriptions or sample requirements. Agree on scope, authorization and a secure exchange method before sharing confidential data.

Form experience

The form checks required fields and preserves entries when you switch language within the same page. Selecting an attachment shows its name and size for review.

Keep a separate copy of important project documents. The page does not provide long-term draft storage. Autofill and history restoration are controlled by your browser settings.

Cookies and browser storage

Browsing loads resources such as pages, styles, scripts and images. Opening or downloading a resource also requests the corresponding file.

This website does not use advertising trackers or third-party analytics, and it does not save inquiry drafts in cookies. Browsing the public website does not require a login.

When you pause or resume background motion, the page saves your choice in sessionStorage under sixuan-background-paused to keep the setting within the same tab. This value is used only for your motion preference, not to identify you or track browsing. It is normally cleared when the tab is closed. You can also clear it through your browser’s site-data settings, which resets the motion preference.

Inquiry entries remain in page memory when you switch languages on the current page; they are not saved as long-term drafts. Your browser settings control caching, autofill and session restoration.

Bilibili and Douyin are external links. Once opened, those platforms may use cookies or other storage under their own policies. This website does not embed their players or tracking components.

If we introduce analytics, advertising or other storage features that require consent, we will explain their purpose, duration and relevant third parties before enabling them, with ways to accept, reject and withdraw your choice.

Use, protection and retention

Project discussions follow a minimum-necessary approach. Information use is guided by the discussion purpose, your authorization and the project agreement. Project materials are not used for unrelated advertising.

Access, exchange methods and confidentiality requirements should reflect the sensitivity of the materials. Where a partner needs to participate, responsibilities, necessary access and confidentiality arrangements should be agreed first.

Materials should be retained only for as long as needed for the agreed purpose, taking account of contractual and applicable requirements. Materials should then be deleted, returned or anonymized as agreed.

Your choices and requests

You decide whether to complete optional fields and can adjust materials before sharing them.

To ask about, correct or delete information relating to you, or raise a concern about its use, email [email protected] with your request and project context. You can also call +86 157 0790 7873 to discuss how to contact us. Begin with the minimum information needed to identify the matter, without including identity documents or other sensitive material.

Handling a request may require verification of your relationship to the information and consideration of project and applicable requirements. Avoid disclosing information about others or confidential materials beyond the request scope.

Updates and language

We may revise this policy as website features and business processes change. The date at the top records the latest update. Material changes will be explained on the relevant page or feature.

The Chinese and English versions provide corresponding information. Please contact us with any questions about the wording in relation to a specific matter.
