Privacy Policy
苏州鸿基洁净科技股份有限公司
Scope and operator
This policy describes personal-information processing by Suzhou HJClean Tech Co., Ltd. (苏州鸿基洁净科技股份有限公司, “HJ”) through hjclean.com. It covers browsing, product inquiries and authorized administrator use. The website is intended for business procurement and technical inquiries, not services directed at children.
Information you submit
The contact form collects your name, telephone number, company and project requirements; email is optional. It also stores the submission time, source page path, requested product, language and a duplicate-prevention identifier. We use this information only to receive, assign, handle and respond to your inquiry. Submitting an inquiry does not subscribe you to marketing. Provide only necessary information; do not include identity documents, bank details, medical information or unrelated information about others.
HJ AI Assistant
When you use the AI Assistant, your question and selected equipment category are sent to this website’s support service. Your question and necessary excerpts from company manuals and FAQs are sent to Alibaba Cloud Model Studio in Beijing, mainland China, to generate an answer. Each question is handled independently; earlier chat turns are not sent with a new question. Do not submit identity documents, bank details, medical information, passwords, API keys or unrelated information about other people. Answers use the available documents; contact human support to confirm actual equipment configurations and matters requiring review.
Access logs and administrator information
To operate the site, diagnose faults and prevent abuse, servers record IP addresses, request methods, paths, response status, response size and processing time. Administrator accounts also involve email, name, role, login sessions and multi-factor authentication information for identity and access management. When email-code sign-in is enabled, Alibaba Cloud DirectMail in Hangzhou processes the administrator’s registered email address and a short-lived sign-in code to deliver the message. Delivery outcomes are recorded for security and troubleshooting; codes are not stored in logs. Administrator information is not intended for public display.
Cookies and similar technology
The hj_locale cookie remembers Chinese or English preferences for one year and may be refreshed on subsequent visits. The hj_analytics_consent cookie stores your choice to allow or decline analytics for one year. Administrator authentication uses cookies with the hj_admin prefix; server login sessions normally last eight hours. Browser controls can clear or restrict cookies, which may affect preferences or administrator login.
Baidu Analytics
After you explicitly agree, the public website uses Baidu Analytics to measure site traffic using cookies, visited pages, referring pages, IP addresses, browser and device information. Declining does not affect the site. You can change your choice or withdraw consent using the analytics options above this page. Analytics is excluded from administrator pages and local development. For Baidu’s processing and retention practices, see the Baidu Analytics Privacy Policy.
Storage, access and service providers
The website database and routine application backups are hosted in Alibaba Cloud’s Shanghai region in mainland China. Only authorized personnel access personal information to handle inquiries, manage accounts, maintain systems and perform related duties; Alibaba Cloud supports hosting and backups as an infrastructure provider. We do not sell or publicly disclose personal information obtained through this site, and we do not proactively transfer the inquiry or administrator account databases outside China. Administrator sign-in emails are delivered to the registered mailbox; subsequent processing and storage locations depend on the recipient’s email provider. If processing arrangements or recipients change, we will provide notice and complete any legally required steps. If you continue communicating with us by telephone, email or WeChat, the rules of those channels’ service providers also apply.
Retention and deletion
Inquiry records are kept for no more than six months from submission; HJ reviews them monthly and deletes records when due. A legal obligation or a specific dispute or investigation may require limited, restricted retention for longer. Identifiable access and security logs are kept for six months, or longer where required by law or necessary to address a security incident. Administrator account information is kept while access is authorized and for no more than six months after access ends, then deleted or anonymized unless law requires retention. Routine application backups follow a ten-day retention policy, although lifecycle deletion may take a little longer. Backups are used for recovery, not routine inquiry handling. Copies of records deleted from the live system are removed as the backups expire.
AI chat retention and deletion
Chat content and diagnostic copies, including questions, answers, retrieved passages and raw model results, are normally kept for thirty days and removed in the next daily maintenance cycle after expiry. Encrypted backups are retained on a rolling ten-day basis; deleted online content may remain in pre-deletion backups for up to another ten days. Backups are used only for recovery. Expired and deleted records are handled before a restored service is reopened. Necessary request fingerprints, deletion markers and usage records are kept separately with restricted access to prevent duplicate charges and reconcile costs. Their continued retention is reviewed periodically; they are not treated as anonymous information. Clear chat removes the current page’s display, not the server records immediately. To request deletion, use the privacy-request channel below.
Your rights and privacy requests
Subject to applicable law, you can request access, a copy, correction, completion or deletion of personal information, withdraw consent and request an explanation of processing rules. Withdrawal does not affect lawful processing before withdrawal. Call 400-6555-379 to make a privacy request; hotline staff will route it to the person responsible for personal-information protection at HJ. We may reasonably verify identity to protect your information and will respond in a timely manner as required by law. market@hjclean.com is for general business inquiries, not the designated privacy-request channel.
Security, external sites and updates
Access controls, administrator authentication and backups help protect information, but no system can guarantee absolute security. External sites and services have their own privacy rules. If processing purposes, information types or methods change, we will update this policy, explain material changes and obtain any renewed consent required by law. This policy takes effect when formally published on hjclean.com.
