Privacy policy

This policy explains what information molecalculator.com handles. Last updated 8 November 2026.

Calculations

The formulas and numbers you type into a calculator are processed in your browser. They are not sent to us or stored. A formula you type into the molar mass tool may appear in the page address so that you can bookmark or share the result.

Visitor statistics

Visits are counted with a self-hosted, cookie-free analytics tool that records the page viewed, the referring site, the browser type and the country derived from the connection. The site may also use Google Analytics to measure visits; Google may set cookies and processes this data under its own privacy policy. Neither builds a profile of you for this site, and the statistics are not sold to anyone.

Server logs

Like any web server, ours keeps short-lived technical logs (IP address, time, page requested, browser) to keep the site secure and working. Logs are deleted on a rolling basis.

Contact form and email

If you write to us, we receive your name (if given), your email address and your message, and use them only to reply. You are not added to any mailing list.

Advertising

The site carries no advertising. A small setting in your browser’s local storage remembers whether you chose the light or dark theme.

Your choices

You can ask for any message you sent to be deleted by writing to info@molecalculator.com. Browser settings let you clear cookies and local storage at any time.
