Who We Are
Valve Knowledge Hub (valveknowledgehub.com) is an educational website about industrial valves, actuators, and related piping equipment. Our content is written for engineers, technicians, and procurement professionals and is provided for general educational purposes only.
If you contact us by email at liujinghui1987@163.com, we receive the email address and any information you choose to include in your message. We use that information only to respond to your inquiry and we do not share it with third parties.
What Information We Collect
We do not require visitors to create accounts, and we do not operate forms that collect personal information on this site. The information we may collect falls into two categories:
- Server logs. Like most websites, our hosting and caching services keep standard server logs that may include your IP address, browser type, pages visited, and the date and time of your visit. These logs are used for site security, performance monitoring, and troubleshooting.
- Cookies and analytics. This site uses Google Analytics (set up through the Google Site Kit plugin) to understand how visitors use the site. Google Analytics sets cookies such as _ga and _gid that collect anonymous usage statistics, including pages visited, approximate location, device type, and referring sources. Google processes this data under its own privacy policy, and we use the reports only in aggregate to improve our content. The site also uses technical cookies related to caching and site performance optimization, which do not contain personal data that identifies you by name.
How We Use Information
We use server logs and technical cookies to keep the site secure, fast, and available. We use Google Analytics reports to understand which content is useful to our readers and how visitors find the site, always at an aggregate level. We do not sell, rent, or trade personal information, and we do not use it for automated decision-making that affects you.
Advertising
Valve Knowledge Hub may offer advertising space on the site. If and when third-party advertising or analytics services are integrated, those services may set their own cookies and process data according to their own privacy policies. We will name those services in an update to this policy at that time.
Your Rights
Depending on where you live, you may have rights under laws such as the EU General Data Protection Regulation (GDPR) or the California Consumer Privacy Act (CCPA), including the right to access, correct, or request deletion of personal data we hold about you. Because we do not operate accounts or forms, we generally hold no personal data beyond server logs. To exercise any right or ask a privacy question, email liujinghui1987@163.com and we will respond within a reasonable time.
External Links
Articles on this site may link to third-party websites, standards organizations, or manufacturers. We are not responsible for the privacy practices or content of those external sites, and their own policies apply when you visit them.
Children’s Privacy
This site is intended for a professional, adult audience and is not directed to children under 13. We do not knowingly collect personal information from children.
Changes to This Policy
We may update this Privacy Policy from time to time. The date below shows when it was last revised. Significant changes will be reflected in the updated policy on this page.
