calculate.at is a free, no-signup calculator platform with more than 290 tools covering everyday finance, health, math, construction, science, unit conversion, dates, and a handful of casual games. There's no account to create, no email to hand over, and no paywall anywhere on the site — every calculator loads instantly and gives an answer in the browser.

The core idea behind the site is transparency.
