Privacy policy for the zai.gr.com reference site

Scope of this policy

This policy covers zai.gr.com only — an independent reference site, not the upstream Z.ai (Zhipu AI) website.

The zai.gr.com domain is operated by an independent editorial team that publishes reference content about the Z.ai brand and the Zhipu AI ecosystem. This site does not handle account log-in for any upstream platform, does not process payments, does not run inference, and does not host model weights. Anything a reader does on the upstream Z.ai or BigModel surfaces falls under that operator's privacy policy, not this one.

What this site collects

Anonymous aggregate analytics, basic server logs, and any information a reader voluntarily sends in via email — nothing more.

The site uses a privacy-respecting analytics pipeline that records anonymous, aggregate page-view counts, referring sources, and approximate region. Individual visitors are not tracked across sessions, and no identifiers are passed to third-party advertising networks. Server logs (typical for any web server) record IP addresses, request paths, and response status codes for security and debugging purposes; those logs are rotated on a short schedule.

If a reader writes in via email — for editorial corrections, partnership requests, or media inquiries — the email is read by an editorial team member and the reply happens from the same address. Email correspondence is not added to any marketing database, never shared with the upstream Zhipu AI / Z.ai company, and never sold to advertising vendors.

Reader rights under GDPR and CCPA

Readers in Europe and California have additional rights to request review, correction, or deletion of any data this site holds about them.

Under the European General Data Protection Regulation, readers have the right to access any personal data this site holds, the right to correct inaccurate data, the right to request deletion (subject to legitimate-interest exceptions), the right to data portability, and the right to lodge a complaint with a supervisory authority. The plain-language guide on gdpr.eu explains the underlying framework and reader entitlements in clear terms.

Under the California Consumer Privacy Act, California residents have parallel rights: to know what categories of personal information are collected, to request access to specific pieces, to request deletion, and to opt out of any sale of personal information (this site sells no personal information). Federal consumer-protection background guidance from the FTC covers companion principles that apply across US states.

To exercise any of these rights, readers can email the address listed on the reach-team page. Requests are answered within thirty days. Identity verification is performed in proportion to the sensitivity of the request — a request to delete email correspondence requires confirmation that the request is from the original sender's email account.

Cookies and similar technologies

A short list of cookies is used; none of them are used for cross-site advertising.

Strictly necessary cookies handle session continuity and security tokens. Analytics cookies record anonymous visit counts. No cross-site behavioural advertising cookies are placed by this site. Readers can disable cookies in browser settings; the analytics-cookie disable will not affect any reader-facing functionality on this site.

Changes to this policy

Material changes are dated at the top of the page and announced in the editorial change log.

This policy is reviewed at least annually and whenever a material change to data handling occurs. The effective date at the top of the page reflects the last review. Readers who need a copy of an earlier version can request it through the contact email; older versions are retained in the editorial change log for transparency.
