What you type

Every calculation runs inside your browser. The numbers you enter are not sent to a server and are not stored. Closing the page clears them.

No accounts

There is no sign-up and we do not ask for your name or email address. This site does not set its own cookies.

Visit statistics

We count page views with Cloudflare Web Analytics (since October 2, 2026) to see which pages are useful. It does not use cookies and does not collect information that identifies you.

Advertising

This site shows ads from Google AdSense. Google and its partners use cookies to serve ads based on your visits to this and other websites. You can turn off personalized ads in Google Ads Settings, and you can read how Google uses data in Google's advertising policy. You can also opt out of some third-party vendors' cookies at aboutads.info. What you type into the calculators is never shared with advertisers.

Fonts and hosting

Fonts load from Google Fonts, and the site is hosted on Cloudflare Pages. Like any web server, they may keep standard access logs such as your IP address and the time of the request, under their own policies.

Changes

If anything above changes, this page will be updated first.
