About Tools.land
A small collection of free calculators that do one thing each — and do it well.
What this is
Tools.land is a set of free, fast, private calculators. Percentage, age, dates, tips, discounts, units, BMI, loans — the everyday things people search for and use once. No accounts, no tracking, no signup. Everything runs in your browser.
Why it exists
Most calculator sites are slow, cluttered, and buried under ads. This one is the opposite. Every page loads fast, every calculator explains the formula, and ads are limited to two non-intrusive slots per page — never above the calculator, never between your input and your result.
How it is built
One HTML file per calculator. Vanilla JavaScript, no framework. Static assets served by a small Node server. No database, no cookies for tracking, no third-party analytics that follow you around the web. Messages from the contact form are stored privately.
Privacy
Calculations never leave your device. We do not log your inputs. We do not know what you calculated. The only things we record are anonymous page views — how many people used each calculator — so we know what to build next.
Accuracy
Formulas are standard and verified against manual calculation. Health and financial calculators include disclaimers and are for guidance only. If you spot an error, please get in touch.
