About Calculy
A small almanac of everyday calculators. No accounts, no ad pop-ups, no tracking — just answers.
Why this exists
Search for compound interest, days-until-X, or square-meter-to-pyeong and you'll find dozens of look-alike sites where ads cover the screen and a consent banner stands between you and the calculator.
Calculy aims for the opposite. The tool is the first thing you see, the answer sits where your eyes naturally go, and nothing follows you out the door.
Principles
It's a place for tidy, single-purpose tools. Every calculation runs in your browser; nothing you type is sent to a server.
- Calculations stay in your browser — your input is never stored.
- No accounts. Land, get the number, leave clean.
- Korean and English are both first-class — /ko and /en stand on equal footing.
Where it's going
Five categories — finance, date & time, units, health, and miscellaneous — will grow gradually. If there's a calculation you reach for often, let us know.
