Pankaj P. Patel
Founder & Developer
I started UnCalculator to build simple, accurate, and completely transparent calculator tools that run instantly in the browser. I design and code the algorithms so you get clear, evidence-based results without data collection or account walls.
About UnCalculator
UnCalculator was created to solve a common problem: online tools are often slow, cluttered with intrusive ads, and hidden behind registrations. UnCalculator is designed as a fast, multi-page application built on top of robust mathematical equations.
Our commitment is to absolute transparency. Every calculator page displays the underlying formula we use, where the data comes from, and cites authoritative sources like peer-reviewed medical journals or government regulatory sites.
Founder Responsibilities
Product Development
Designing the overall product vision, roadmaps, and calculator functionalities.
Calculator Engineering
Coding deterministic math algorithms, equations, and testing dynamic scenarios.
Technical SEO
Implementing structural data, canonical targets, and crawlable multi-page routing.
Accessibility & Performance
Optimizing code payloads, markup hierarchy, and color contrast compliance.
Design System
Maintaining the V2 design language, fluid typography, and dark mode compliance.
Quality Assurance
Testing calculation results against known edge cases and regulatory schedules.
Core Philosophies
Accuracy Before Speed
Every calculator logic is thoroughly audited against authoritative math, financial regulations, or health standards before release.
Privacy & Trust
Calculator inputs are processed locally within your browser. We never collect or track your financial or medical details.
Evidence-Based Content
Calculation details rely on public, reputable research standards (such as WHO, CDC, IRS) and undergo editorial verification.
Inclusive User Experience
Clean, minimal layouts and rigorous color contrasts make calculations accessible to users of all devices and abilities.
Development Timeline
Website launched with core mathematical, date, and unit calculators executing client-side.
Introduced compound interest planners, amortization logic, and regional financial frameworks.
Redesigned user experience with modern fluid typography, accessibility upgrades, and dark-mode support.
Plans to add embeddable visual charting libraries and responsive scenario comparative engines.
Editorial Transparency & Formulas
While I personally architect and develop the codebase, the mathematical and editorial logic is separate. Educational descriptions, health formulas, and tax schedules are researched using authoritative public datasets.
Calculators explicitly disclose their underlying equations. If you find a bug, logic mismatch, or have suggestions for improvements, please reach out to contact@uncalculator.com or open a ticket on our contact page.
