How This Attendance System Works

This tool is built using modern web technologies such as HTML, CSS, and JavaScript. Instead of storing data on an external server, it uses browser local storage. This means once attendance is marked, the data remains securely saved in the browser. Even if the page is refreshed or the browser is closed, the attendance history will remain intact until the user manually clears it.

Each month’s data is stored separately. When you switch between months using navigation buttons, the tool automatically displays the correct attendance summary for that specific month. This prevents mixing of data between different months and ensures accurate record keeping.
