About Us

We're a small team of IT experts. Our goal is to create quality, popular online tools that people actually use.

Who we are

We focus on calculators and utilities that solve real problems: percentages, fractions, finance, fitness, dates, and conversions. We aim for clarity, correct results, and no clutter.

How it works

This app is built with Next.js. All calculators run on JavaScript and every calculation happens in your browser using your device—we don't send your numbers to our servers. There is no backend for the calculators themselves. The only server-side parts of the site are the blog and the contact form.

What we care about

A few principles we follow:

Quality. We use solid formulas and test our tools. When something's wrong, we fix it.
Privacy. Your inputs stay in your browser. We don't collect or store calculation data.
Simplicity. No sign-up, no paywall. Find the tool, get the result, done.

This site is owned and operated by RNX IT Technologies SRL.

Thanks for visiting. Use the tools, share them if they help, and get in touch if you have ideas or spot an error.
