About Harsh
Harsh is a digital product creator based in Jaipur, Rajasthan with a background in building web tools that make professional-grade information accessible to everyone. He founded PapaSiddhi as a platform for the digital products he builds — tools designed to be fast, clear, and useful without the clutter of dark patterns or paywalls.
He built Cloud Calculators App because he couldn't find a calculator site that was simultaneously clean, fast, and genuinely privacy-respecting. Every calculation on this site runs entirely in your browser — no data is sent to any server, no account is required, and no behavioral tracking is buried in the product. The goal is a tool you can actually trust with sensitive financial and health inputs.
Harsh personally reviews every calculator formula against official sources — IRS publications for tax calculators, WHO and peer-reviewed research for health metrics, and CFPB methodology for mortgage and loan tools — before any calculator goes live. When official guidelines change (such as annual IRS tax bracket adjustments), he updates the affected calculators to reflect the current year's figures.
Why I Built Cloud Calculators App
I got frustrated searching for simple calculators online and landing on sites bloated with ads, requiring signups, or giving results I couldn't trust. I wanted a clean, fast, privacy-first calculator platform where every formula is verified and every result can be trusted. That's what Cloud Calculators App is.
My Approach to Accuracy
Every calculator on this site uses formulas sourced from authoritative references — the IRS for tax calculations, the WHO for health metrics, the CFPB for mortgage math. I personally review each formula before publishing. If you ever find an error, email contact@cloudcalculatorsapp.com and I'll fix it within 24 hours.
