About Us

Attendance Calculator was born out of a simple need: a fast, private, and reliable way for students and professionals to track their presence without the clutter of traditional apps.

Our Mission

We believe that utilities should be invisible. You shouldn't have to create an account, watch ads, or worry about your data being sold just to calculate your attendance percentage. Our mission is to provide high-performance, privacy-first tools that help you manage your time effectively.

Why Choose Us?

• Privacy by Design: Your data never leaves your device. We use browser LocalStorage to save your calculations, ensuring complete anonymity.
• Minimalism: No "marketing fluff," no distractions. Just the calculator and the information you need.
• Developer-Centric: Built with modern technologies like Astro and Tailwind CSS for lightning-fast load times and a premium user experience.

The Tech Stack

This tool is built using Astro 6 and Tailwind CSS v4. By leveraging static site generation and minimal client-side JavaScript, we've achieved near-perfect performance scores while maintaining a sleek, dark-mode-ready interface.
