Privacy Policy

What we collect

Nothing on our servers. The words, names, and phrases you type into any calculator on this site are processed entirely in your own browser using JavaScript — they are never transmitted to, logged by, or stored on any server we operate.

Calculation history (localStorage)

The "Recent calculations" feature saves your last 12 entries using your browser's localStorage, a standard web technology that stores data only on your own device. This data never leaves your browser, is not accessible to us, and is automatically scoped separately per device and browser. You can clear it at any time using the "Clear" button next to your history, or by clearing your browser's site data.

Cookies and tracking

This site does not currently set tracking cookies, does not run third-party analytics or advertising scripts, and does not use fingerprinting. If that changes in the future, this page will be updated to disclose it before any such change takes effect.

Server logs

Like any website, our hosting provider may log basic technical request information (such as IP address, requested URL, and timestamp) for security and reliability purposes, in line with standard web server operation. We do not use this information for tracking or advertising.

Embedded calculator widget

If you encounter our calculator embedded on another website (via our embed feature), the same rules apply: your input is processed locally in your browser within that embedded frame and is not transmitted to us.

Changes to this policy

If our data practices change — for example, if we add optional analytics — we will update this page and the "Last updated" date above before the change takes effect.
