In short: what you type into a calculator never reaches us. Every calculation runs in your own browser.
Stored on your device
For convenience, a few things are kept only in your browser’s local storage, never on our servers:
- your last inputs, so you don’t have to retype them
- the list of calculators you used recently
- your preferences: dark/light mode, text size, language
Pressing “Reset” on a calculator, or clearing site data in your browser, removes them.
Statistics
To understand visitor numbers we may use Cloudflare Web Analytics, which uses no cookies and does not identify you personally.
Shared links
“Copy link” puts your inputs into the URL so the person you send it to sees the same calculation. Think before sharing a link that contains personal figures.
Advertising
There are no ads on the site today. If ads are added later, this policy will be updated and consent requested where required.
