Information We May Collect

When you visit this site, the server and frontend scripts may record basic access data such as visit time, page URL, browser type, device type, referrer, approximate region, IP address, and error logs. This helps debug failures, improve page experience, and understand content readership.

Cookies and Local Storage

The site may use cookies or browser local storage to keep theme preferences, basic traffic statistics, and information required by third-party services for ad delivery, fraud prevention, frequency control, and performance measurement.

Traffic Analytics

ZiCode uses Google Analytics 4 and Baidu Tongji to understand page views, traffic sources, device types, approximate regions, reading behavior, and content trends. The site also records on-site events such as article reading depth, site search, tag and category clicks, RSS and GitHub link clicks, and WeChat QR-code views or interactions. These services may use cookies, device data, IP addresses, browser information, and page-view records to generate aggregated analytics reports. These analytics events do not ask you to provide direct identifiers such as your name or phone number.

Google Analytics 4 is provided by Google, and Baidu Tongji is provided by Baidu. You can limit or clear cookies through your browser settings, and you may use browser privacy, ad-blocking, or tracking-protection features to reduce third-party analytics collection.
