Privacy Notice

For visitors to our site and inbound business enquiries

Last updated: May 3, 2026

Yixi Technology Trading (Shanghai) Co., Ltd. (registered in the China (Shanghai) Pilot Free Trade Zone; “we”, “us”, or “our”) respects your privacy. This notice describes how we may process information when you browse our website, email us, or submit enquiry forms relating to our work in precision metrology, cleanroom & aerosol instrumentation, electrochemical analysis, technology promotion, training, local lifecycle support, and compliant trade services (including programmes involving ZYGO, TSI, AMETEK, and related brands). This notice focuses on our public website and these online touchpoints.

1. Information we may collect

Depending on how you interact with us, we may collect:

  • Information you provide, such as name, company, phone number, email address, subject line, and message body submitted via contact or quote forms, or content you send to published addresses (e.g. info@yixi-tech.com).
  • Technical data, such as browser type, approximate region (where routinely logged by networks), timestamps, pages viewed, and referral URLs. Such data may not identify you on its own but can still be treated as personal information when combined with other data.

2. How we use information

We use information only where we have a lawful basis and a legitimate need, typically to:

  • Respond to product, technical, partnership, or service requests;
  • Follow up on the enquiry channel you provided;
  • Perform contracts, maintain business records, and meet compliance duties;
  • Improve site security, structure, and performance using aggregated or de-identified statistics where possible.

We do not sell your contact details to unrelated third parties for their independent marketing.

3. Form delivery and service providers

Contact forms may rely on a third-party form or email relay (for example FormSubmit) to deliver messages to our corporate mailbox. That provider acts as a technical processor under its own terms. Please avoid submitting highly sensitive personal data (e.g. bank card numbers, ID imagery unrelated to your enquiry) through the website.

4. Retention and security

We keep information only as long as needed for the purposes above or as required by law. We apply reasonable technical and organisational safeguards. No online transmission or storage method is completely secure; we encourage prudent sharing aligned with the sensitivity of your enquiry.

5. Sharing

We share information only where necessary:

  • With your consent or at your direction;
  • To deliver services you requested or to conclude discussions leading to a contract;
  • Where law requires or permits disclosure to authorities;
  • With processors bound by contract (e.g. hosting or email infrastructure) strictly as needed for the purposes described.

6. Your rights

Subject to applicable Chinese privacy and data-protection laws, you may request access, correction, supplementation, deletion, restriction, or portability where available, or withdraw consent where processing was consent-based. Contact us using the details below. You may also lodge a complaint with a competent regulator where the law allows.

7. Children

Our site is oriented to organisations and professional users. We do not knowingly seek personal data from minors. If you believe a minor has sent us data, please notify us and we will take appropriate steps.

8. Changes

We may update this notice to reflect legal, technical, or business changes. The date at the top will be revised; material changes may be highlighted on the site where appropriate.
