About Sitix.top

Our Mission

Sitix.top exists because we got tired of searching for simple calculators and ending up on sites buried in pop-ups, forced sign-ups, and questionable downloads. We wanted a place where you could type a number, get an answer, and move on with your day. So we built one.

Every tool on this site is designed to do one thing well. No bloat, no unnecessary features, no data harvesting. You type in your numbers, you get your result, and that's it. We think that's how online tools should work.

What We Offer

We've put together a collection of over 30 calculators and tools covering five main areas of everyday life:

  • Health & Fitness — BMI, calorie needs, body fat, water intake, heart rate zones, sleep cycles, pregnancy due dates, and more. These tools help you understand your body better without needing expensive gadgets.
  • Finance — Loan payments, compound interest, mortgage estimates, salary conversions, savings goals, and tip splitting. Because money decisions shouldn't require a finance degree.
  • Time & Date — Age calculator, date differences, timezone conversions. Simple tools for questions that come up more often than you'd think.
  • Math & Converters — Unit conversion, percentage calculations, Roman numerals, color formats, and word counting. The kind of utilities you need occasionally but never remember how to do from memory.
  • Everyday Utilities — Password generation, random numbers, gas mileage, electricity costs, discount calculations, and even a dog age converter. Because sometimes you just need a quick answer.

Our Commitment to Accuracy

We take accuracy seriously. Every calculator on Sitix.top uses established formulas and methods — things like the Mifflin-St Jeor equation for calorie calculations, the Navy method for body fat estimation, and standard amortization formulas for loans. When there are multiple valid approaches (like the several formulas for ideal body weight), we show you results from each one so you can see the range.

That said, our tools are designed for informational purposes. They're not a substitute for professional medical advice, financial planning, or any other expert guidance. We always encourage you to consult qualified professionals for important decisions.

Privacy First

Here's something you don't hear often from calculator websites: we don't want your data. All of our tools run entirely in your browser using JavaScript. That means the numbers you type in never leave your device. There's no server processing, no database storing your results, no analytics tracking your specific inputs.

We do use standard web analytics (Google Analytics) to understand general traffic patterns — how many people visit, which tools are popular, what devices people use. But that's aggregated, anonymous data. We genuinely have no interest in what BMI or salary number you typed in.

Who We Are

Sitix.top is run by a small team of developers and writers who believe the internet should have more genuinely useful, no-nonsense tools. We're not a startup chasing venture capital. We're not trying to build the next big platform. We just want to make a handful of good tools that people actually find helpful.

Between us, we have backgrounds in software development, personal finance, health science, and content creation. We build the tools we wish existed when we're searching for answers to our own everyday questions.
