Privacy & Cookie Policy

This Policy applies to the official websites operated by Suzhou RefineTek Co., Ltd. (including international and domestic web domains).

We process personal data in compliance with the Personal Information Protection Law of the PRC (PIPL), the Cybersecurity Law, the Data Security Law, and the Regulations on Network Data Security Management. For data processing activities involving other jurisdictions, we comply with applicable international standards, including the EU General Data Protection Regulation (GDPR), according to specific business contexts and legal applicability.

We adhere to the data minimization principle, collecting only what is strictly necessary for legitimate technical communication and site operation.

During your visit or communication with this website, we may process two categories of technical data:

• Voluntarily Submitted Inquiries: When you submit an inquiry via our "Contact Us" form or corporate email, you may provide your name, email address, message details, and optional website URL. This data is transmitted directly to our self-hosted infrastructure and is exclusively utilized to respond to your technical requirements, industrial gas inquiries, or business discussions.

• Technical Operations & Security Server Logs: To maintain server availability, diagnose system faults, and defend against malicious cyberattacks, our web servers automatically record request IP addresses, browser types and versions, operating systems, request timestamps, requested URLs, and HTTP status codes. We process this data strictly within the necessary scope of cybersecurity and technical maintenance, maintaining strict access controls. It is never used for user profiling, behavioral tracking, or commercial marketing.

To ensure optimal performance and remember basic interface states, we employ a minimal set of strictly necessary technical cookies / storage items (e.g. refinetek_consent and locale session state).

Factual Confirmation: This website does NOT deploy any third-party analytics cookies, advertising pixels, or cross-site tracking identifiers (including Google Analytics, Baidu Statistics, Meta Pixels, etc.). Your browsing activity is never tracked across external websites or shared with advertising networks. Refer to the table below for exact specifications.

We process collected information strictly for the following legitimate business purposes:

• Responding to client technical inquiries, industrial gas separation equipment specifications, and engineering customer support;

• Processing communications regarding job vacancies and candidate applications;

• Fulfilling legal obligations for network security, monitoring anomaly traffic, preventing malicious attacks, and safeguarding server infrastructure.

We never monetize, sell, or exploit your personal information for unrelated commercial purposes.

• Zero Sale or External Sharing: We strictly pledge never to sell, rent, lease, or commercially transfer your personal information to any third party.

• Self-Hosted Architecture: All contact submissions are received directly by our self-hosted backend systems and stored in protected databases without third-party form-hosting intermediaries.

• Infrastructure Providers: Our website utilizes professional cloud infrastructure for hosting and content acceleration. Infrastructure providers act solely as authorized technical processors under strict confidentiality contracts.

• Cross-Border Data Flows: Personal data collected within Mainland China is stored locally on secure servers. Inquiries originating from international clients are handled strictly by designated business teams necessary to advance that specific project.

In compliance with Article 21 of the Regulations on Network Data Security Management, we apply concrete data retention periods based on business necessity:

• Business Inquiries & Correspondence: Retained for up to 3 years following the conclusion of discussions or active client collaboration for warranty/audit verification, after which records are securely purged;

• Recruitment Resumes: Retained for up to 1 year following the conclusion of the recruitment cycle, after which data is securely erased or fully anonymized;

• Server Security Logs: Retained for a minimum of 6 months in strict compliance with statutory cybersecurity requirements, then rotated and overwritten automatically;

• Cookie State: Stored locally for up to 12 months before re-prompting.
