课间应用

这个网站

In English

Kejian is a planner for teachers. Everything you enter stays on your own computer, in Kejian's data folder. The app sends nothing over the internet: no account, no analytics, no ads, no crash reports, no uploads. We cannot see your data. Backups are files you download and keep yourself. Uninstalling the Microsoft Store version removes its data, so back up first; uninstalling the installer version keeps it. Please handle student information as your school requires.

This website has no analytics, ads or third-party scripts. Entering with an invite code stores one sign-in cookie for a year. The site is hosted by Cloudflare, which handles connection data such as IP addresses under its own privacy policy; we keep no visitor records. The Microsoft Store version is delivered and updated by Microsoft under the Microsoft Privacy Statement.
