Privacy

Only information needed to run the public site.

This page explains how YunLab.ai handles browsing, search, and guestbook interactions.

Browsing and analytics

YunLab uses Umami as its only on-site analytics source for public page visits, qualified_read, and a small fixed set of value actions. A qualified read requires 75% content depth and foreground reading time equal to 40% of the estimated duration. It is recorded at most once per page view.

Events are limited to the current path, language, content kind, public slug, chapter, and a fixed action ID. Browser DNT is respected; query strings and hashes are excluded.

What is not collected

Analytics does not send Ask input, email addresses, free text, complete outbound links, complete referring addresses, or identity data. YunLab does not use advertising profiles, heatmaps, or visit recording.

Ask YunLab

Ask YunLab searches public articles on this site to produce source-linked answers. Do not enter passwords, account details, identity documents, addresses, or other sensitive information. Questions are not published as notes.

Guestbook and email

The guestbook processes the name and message you choose to submit, and approved messages are shown publicly. Email is delivered through your mail provider to the site author. Do not send sensitive information through either channel.

Third parties and contact

Cloudflare processes deployment and basic access logs; Umami processes the bounded analytics described above. Edge request counts are availability evidence, not reader counts. YunLab.ai does not sell visitor information or offer targeted advertising. For privacy questions, email xjzy8092@gmail.com.
