1. What information we collect
This site (www.hhrobots.cn) is the information website of Nanchong Henghuan Industrial Robot Service Center ("Henghuan" or "we"). We follow the data-minimization principle: the site offers no registration, accounts or online transactions, sowe do not actively collect personally identifiable information such as your name, ID number or locationIn practice only two categories of data may be generated:
① Server access logs: your IP address, browser type, visit time, pages visited and referring page (Referer). This data is recorded automatically by the web server and used only for security audits (e.g. detecting malicious scanning and attacks), fault diagnosis and traffic statistics.
② Contact information you submit voluntarily: when you contact us by phone, email (robin@hhrobots.cn), WeChat, Douyin or form — the name, organization, equipment model and requirement description you provide yourself. This information is used only to answer your inquiry, prepare quotes and follow up on service.
2. Cookies and local storage
This site uses a small amount of browser local storage (localStorage) to remember your light/dark theme and language preference so the interface stays consistent on your next visit; this data stays on your device and is never uploaded to our servers. The site uses no third-party advertising cookies and performs no cross-site tracking or profiling.
3. Information sharing and disclosure
We never sell or rent your personal information to third parties. Disclosure may occur only: (1) as compelled by laws, regulations, or judicial/administrative authorities; (2) where necessary to perform a service you commissioned (e.g. logistics or customs clearance), limited to the minimum scope required, with the entrusted party bound by equivalent confidentiality obligations.
4. Retention period and security
Server access logs are kept for no more than 6 months (unless laws and regulations require otherwise); contact information is kept for no more than 3 years after the business relationship ends, for after-sales and warranty traceability. We protect data security with access controls, transport encryption (HTTPS) and similar measures.

Under the Personal Information Protection Law of the PRC, you have the right to access, copy, correct or delete your personal information, or withdraw consent previously given. To exercise these rights, email robin@hhrobots.cn; we will handle it within 15 business days.
