This is a static information site. The frontend does not collect names, phone numbers, addresses, ID documents, API keys, or passwords. We may use third-party analytics (such as Google Analytics or Baidu Analytics) to understand traffic and page performance; analytics data is used internally to improve content quality and is not shared in raw form. Tool pages link to external official websites — once you leave this site, the third-party website's privacy policy applies. For privacy questions email 1055567003@qq.com.
