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.
