Privacy Policy

Last updated: 2026-10-23

Scope of this policy

This policy explains how China AI Hub handles information in connection with the website at sinoaihub.com and its companion reference site at data.sinoaihub.com (together, "the site"). China AI Hub is an independent, English-language knowledge and intelligence platform about China's AI ecosystem — models, agents, APIs, companies, pricing, benchmarks and technology. It is a reference and research site, not an e-commerce store, and it does not require registration or an account.

Who operates the site

The site is operated by the China AI Hub project. The project publishes a contact point and a team-level byline (the SinoAI Hub Research Team); it does not publish a corporate legal name, registration number, or registered office. Contact for privacy matters is the same as the general contact point: Martin.W — [email protected]. The project has no appointed Data Protection Officer; where a supervisory authority or a data subject needs a specific contact, use the email above.

Our approach in one sentence

We practice data minimization by design: the site collects no personal data through forms, accounts or tracking, so there is very little personal data to protect in the first place. The sections below explain the few narrow situations in which information reaches us.

Personal data we collect

The site is designed to collect as little information as possible. It has no user accounts, no login, and no contact forms. There is no newsletter, no comment system, and no user-generated content. Concretely, the only situations in which information reaches us are:

We do not otherwise collect names, contact details, location data, device identifiers, or behavioral profiles, because the site has no mechanism to do so.

What we do not collect

Cookies and similar technologies

China AI Hub does not set tracking, analytics or advertising cookies. Our hosting provider (Cloudflare) may set strictly necessary technical measures at the infrastructure level, such as a bot-management security token (__cf_bm) or its email-protection feature, which decodes our obfuscated contact email address in your browser. These measures keep the site operational and secure and are not used to profile visitors, serve ads, or build marketing audiences. A full classification is in the Cookie Policy.

How we use information

The only information we use is (a) the contents of email or WhatsApp messages you send, which we use to respond to you and to correct or improve the site where you report an error, and (b) the technical logs described above, which are used by our host for security, abuse prevention and availability. We do not use any of this information for marketing, profiling, advertising, or automated decision-making. We do not combine correspondence with technical logs to build a picture of an individual, and we do not build or maintain visitor profiles.

Hosting and server logs

The site is hosted on Cloudflare Pages. Cloudflare may keep standard technical logs (IP address, user agent, request time, and the resource requested) for security and abuse prevention. We do not access or combine these logs to identify or profile individuals, and we do not use them for any commercial purpose. Cloudflare's own processing of this data is governed by Cloudflare's privacy policy; for questions about their infrastructure-level processing, contact Cloudflare directly.

Retention

Because we do not collect personal data through the site, there is effectively no site-collected personal data for us to retain. Email correspondence is kept only as long as needed to handle the matter and is not archived into a marketing system. Technical logs held by Cloudflare are retained by Cloudflare according to its own retention schedules and are outside our control. If you contact us and would like your correspondence deleted, tell us and we will remove what we hold.

Third parties and onward transfers

We do not sell personal data, and we do not disclose it to advertisers, data brokers, or any third party for their own marketing use. The third parties above are infrastructure or communication channels, not data buyers.

Cross-border transfers

The site is served through Cloudflare's globally distributed network, which means your requests may be handled by servers outside your country, and Cloudflare may store technical logs in jurisdictions other than your own. This is the only cross-border element. We collect no personal data ourselves, so there is no separately stored personal data for us to transfer. If you email us, your message is handled by our email provider; see the mail provider's policy for its location and retention.

Legal bases under GDPR (EEA and UK)

For visitors in the European Economic Area and the United Kingdom, we process any personal data on the following bases:

We do not rely on consent for analytics or marketing because we run none. We do not process special-category data, and we do not make decisions based on automated processing.

CCPA / CPRA (California)

For California residents, China AI Hub does not "sell" or "share" personal information in the sense of the California Consumer Privacy Act, and it does not use or disclose sensitive personal information for the purpose of inferring characteristics. The site collects no personal information through forms or tracking. If you nevertheless believe we hold personal information about you (for example, from an email you sent), you may request access, correction, or deletion by emailing [email protected]. We will not discriminate against you for exercising these rights.

Other jurisdictions

This policy describes the project's practices generally, but different jurisdictions grant different rights (for example, under PIPL in mainland China, the UK GDPR, or the privacy laws of Australia, Canada and Brazil). Because the site collects no personal data itself, in most cases the practical answer is the same: there is nothing for us to access, correct or delete beyond any correspondence you have sent us. If you believe a specific right applies to you, contact us and we will respond in accordance with the law that governs your situation.

Do Not Track

Some browsers send a "Do Not Track" (DNT) signal. Because we run no tracking or analytics at all, there is nothing for a DNT signal to disable; the site's behavior is the same whether or not DNT is set. See the Cookie Policy for details on the strictly necessary technical measures set by our host.

Automated decision-making

We do not use personal data to make any decision that produces legal or similarly significant effects concerning you, and we do not profile visitors. The site's only automation operates on public vendor data (re-fetching sources to verify model specifications and prices), not on personal data.

Children

The site is a technical reference for professionals, researchers and developers. It is not directed at children under 13 (or the applicable minimum age in your jurisdiction), and we do not knowingly collect personal data from children. If you believe a child has provided us personal data, contact us and we will delete it.

Security

The site is static content with no login or database of user data, which materially reduces the personal-data surface. Delivery and transport are handled by Cloudflare over HTTPS. No security measure can guarantee absolute security; because we hold no site-collected personal data, the practical risk to visitors is correspondingly low. If we become aware of a security incident affecting personal data we do hold (for example, correspondence), we will address it and notify affected individuals where required by law.

AI-generated images

Illustrations on entity pages are AI-generated (labeled in image credits, e.g. "Seedream") and contain no personal data. The site's text is researched and written by the SinoAI Hub Research Team; analysis is labeled, and automated tooling is used only in the verification workflow described in the methodology. See the Disclaimer for how AI use is disclosed.

Your rights

Depending on your jurisdiction, you may have rights to access, correct, delete, restrict or object to the processing of your personal data, and (in the EEA/UK) to data portability and to lodge a complaint with a supervisory authority. Because the site collects no personal data itself, in most cases there is nothing to exercise these rights over. To the extent you have contacted us and want access to, correction of, or deletion of that correspondence, email us and we will respond within a reasonable time. To help us locate anything we might hold, tell us the email address you used and, if relevant, the approximate date of your message.

Changes to this policy

We may update this policy as the site's practices or applicable law change. The "Last updated" date at the top of this page reflects the most recent revision. Material changes will be reflected here; we do not maintain a mailing list to push notifications, so please review this page when you have concerns.
