About attend75

attend75 is a free attendance calculator for college students in India. Most universities require 75% attendance to be eligible for exams. This tool helps you figure out where you stand and how many classes you can (or can't) skip.

What it does

• Calculates your attendance percentage
• Shows how many classes you can bunk per subject
• Tells you how many classes to attend to recover if you're below target
• Lets you mark daily attendance with swipe cards (like Tinder, but for lectures)
• Works with any course — B.Tech, BCA, BBA, B.Sc, MBA, whatever

Your data

Everything is stored in your browser's localStorage. There is no server, no database, no account. We don't know who you are, what college you go to, or how many classes you bunked. If you clear your browser data, your records are gone — we can't recover them because we never had them.

Why this exists

Because the existing attendance calculators are either ugly, ad-infested, or both. We wanted something clean that actually works and doesn't need you to create an account just to divide two numbers.
