Privacy policy

Short version: the calculators run in your browser, and the numbers you type never leave it.

What we do not collect. No accounts, no sign-up, no contact form, no tracking cookies of our own. The values you enter into a converter are processed by JavaScript on your device and are never transmitted to a server.

What is stored locally. Three small settings live in your browser's local storage: the light or dark theme you picked, the number of digits you want results shown to, and the language you chose. They stay on your device, are readable only by this site, and clearing your browser data removes them.

Server logs. Like any website, the hosting provider records standard request data — IP address, time, page requested, user agent — for security and traffic statistics. These logs are not linked to any identity and are not used for profiling.

Third parties. If advertising is enabled on a page, the ad provider may set its own cookies under its own policy; that block is clearly marked in the page markup. No other external scripts, fonts or analytics are loaded — the site ships with its own CSS, one JavaScript file and self-hosted fonts.

Children. The site is a calculator with no personal data collection, and is suitable for any age.

Changes. If this policy changes, the revised text replaces this page and the date below is updated.
