We build free, fast, and privacy-first tools for professionals across India, Qatar, UAE, Kuwait, and Bahrain — no signups, no data collection, no paywalls.
Our Promise: Every calculator on AboutAll.in runs entirely in your browser. Your salary, tax details, and personal data never leave your device. We believe useful tools should be free and private.
AboutAll.in is an independent tools platform created by a team of developers and finance enthusiasts who saw a gap in the market: most online calculators are cluttered with ads, require unnecessary signups, or produce inaccurate results based on outdated tax rules.
We set out to build a comprehensive collection of HR, finance, and developer tools that are genuinely useful, accurate to current regulations (updated for 2026), and completely free to use. Our tools are designed for salaried professionals, HR managers, accountants, freelancers, and Gulf expatriates who need quick, reliable answers.
Our platform covers a wide range of tools organized by region and category:
All calculations happen in your browser. We never see your salary, tax data, or personal information. Zero server-side data storage.
Every tool is free to use, forever. No premium tiers, no feature locks, no signup walls. We sustain the site through non-intrusive advertising.
Our calculators use the latest tax slabs, labour laws, and financial formulas. We update them when regulations change so you get correct results.
No bloated frameworks or heavy libraries. Pages load in under 2 seconds on any device. Works perfectly on mobile, tablet, and desktop.
Use any tool instantly without creating an account. We don't need your email address to help you calculate your salary or format JSON.
Our formulas and calculation methods are visible in the page source. We show you how results are derived so you can verify them yourself.
We take accuracy seriously. Here's how we ensure our tools give you correct results:
