Hey Product Hunt community! 👋 As a student, I was tired of clicking through slow, ad-choked calculator websites that track everything, lag on mobile, and display outdated conversion formulas. So I built **ScholarKit** (https://scholarkit.org) — a free, open-source academic utility toolkit designed with three non-negotiable principles: 1. ⚡ **Sub-Second Speed:** Built on Astro static site generation and hosted globally on Cloudflare’s edge network. 2. 🔒 **100% Client-Side Privacy:** Zero servers, zero user accounts, zero databases. All calculations happen inside your browser’s local memory. 3. 🎯 **Real-World Academic Formulas:** Covers universal weighted scales (4.0, 5.0, 7.0, 10.0, and custom) plus official conversion rules for CBSE, VTU, AKTU, GTU, Anna University, Mumbai University, and JNTU. It also features a drift-resistant Pomodoro timer (that doesn't freeze when switching tabs) and an attendance planner to calculate exact attendance quotas for semester exams. I’d love to hear your feedback, tool requests, or suggestions!
