Copyright and ownership
Website text, product photographs, drawings, catalogs, layout, logos and other materials are owned by TENCAN or used with permission, unless a different owner is identified. Third-party names and marks remain the property of their respective owners.
You may read, print and download public product information for equipment evaluation, purchasing discussions and internal reference. Keep copyright and source notices attached. You may share links to public pages without presenting them as your own work.
For republication, translation, advertising use or distribution of substantial materials, request written permission. Do not remove identifying marks or use the TENCAN name or images to imply an endorsement, dealership or partnership that has not been authorized.
Information you provide
Inquiry forms request your first name, email address and project message. Last name, company and phone or WhatsApp number are optional. A sample evaluation request may also include material and process details. Product references and the originating page may be included to help us understand the inquiry.
We also receive information you choose to send by email, phone or WhatsApp, such as drawings, photographs, test objectives and service correspondence. Share only information needed for the discussion. Do not submit sensitive personal information or confidential third-party data without authorization.
Why we use the information
- Respond to your inquiry and discuss equipment, accessories or test arrangements.
- Prepare quotations, manage order-related communication and coordinate delivery.
- Provide operating guidance, documentation and after-sales support.
- Prevent spam and misuse, diagnose technical problems and maintain website security.
- Maintain records required for business operations and applicable legal obligations.
Submitting an inquiry does not create an equipment order or subscribe you to a marketing mailing list. If you receive non-essential promotional communication, you may ask us to stop.
Website data, cookies and statistics
Our servers record technical request information such as IP address, requested page, browser information and request time. The website also records first-party page visits and article views using its own statistics service. It records visitor and session identifiers, browser, device, operating system, referring page and visit time. A visitor identifier cookie can last up to one year; session cookies may also be used. These statistics run when a page is opened with JavaScript enabled.
When form verification is enabled, a session cookie keeps the verification challenge associated with your browser. Third-party analytics and advertising scripts are not currently enabled on these pages.
Open in the footer to read the storage information. The remember button saves only an acknowledgment of this notice in browser local storage for 180 days. It contains a version, acknowledgment and save/expiry times, not your inquiry details. This dialog does not enable or disable statistics. Reset removes the acknowledgment, not existing cookies, visit records or submitted inquiries.
You can clear or block cookies and local storage using your browser settings. Blocking cookies does not stop every server request or article-view count, and blocking session cookies may prevent verification-enabled forms from working.
External maps, email and WhatsApp are links you choose to open; they are not embedded tracking widgets on these pages.
Sharing and service providers
TENCAN does not sell personal information. Information may be shared with staff and providers who need it to handle your request, such as hosting and email providers, technical service partners or logistics providers involved in an order. We may also disclose information where required by applicable law or to protect legitimate rights and website security.
The information needed for a product inquiry differs from the information needed to deliver an order. We aim to limit sharing to the relevant purpose.
International handling
TENCAN is based in China and works with customers internationally. Your inquiry may therefore be handled in China and by service providers in other locations. Data protection rules may differ between locations. Contact us if your organization has particular requirements before sending confidential or restricted information.
Retention and security
Inquiry, quotation and service records are kept for the period needed to respond, follow up, maintain relevant business records and meet applicable obligations. Retention depends on the type of information and the continuing business relationship; we do not promise that every record is deleted immediately after a reply.
We use reasonable safeguards for website and business information. No internet or email system can guarantee absolute security. Contact us to agree an appropriate exchange method for confidential project files.
Your choices and requests
You may ask about information you have provided, request access or correction, ask for deletion or limitation of use, or object to non-essential marketing, subject to the rights and recordkeeping requirements that apply. We may need to verify that a request relates to you before releasing or changing a record.
Email lichang0516@gmail.com with the relevant inquiry reference and the change or information requested. Please avoid sending identity documents unless a suitable verification method has been agreed.
External services and intended audience
When you choose an external link, the receiving service's terms and privacy practices apply. This website is intended for business, research and laboratory users, and is not directed at children. If you believe information about a child has been submitted inappropriately, contact us.
Changes and contact
We may revise this notice when website functions or information-handling practices change. The update date identifies the version displayed here. Read the Website Terms for equipment information and inquiry conditions, or contact TENCAN with copyright or privacy questions.
