About and Contact
CloudyUnicorn Tools is a suite of premium, ad-free, and privacy-first online calculators designed by builders, for builders.
Our Philosophy
The modern web is filled with clutter. Visiting a simple calculator page shouldn't mean scrolling past banner advertisements, dodging cookie consent walls, or fighting popups asking you to sign up for newsletters.
We built CloudyUnicorn Tools to return to the fundamentals: fast, functional, and minimal utilities that do one job exceptionally well, with zero data collections or tracking.
100% of our code runs directly in your browser. None of your input data is ever stored, analyzed, or sent to a remote database.
We implement verified clinical and mathematical models (WHO guidelines, Harris-Benedict formula) ensuring developer-grade precision.
Our Stack
This suite is built using **Astro** for server-side static layout rendering, combined with **Tailwind CSS v4** for clean, theme-adaptive layouts, and vanilla **client-side JavaScript** for reactivity. There are no heavy frameworks or tracking scripts running in the background.
