Privacy policy

This policy explains what information this-calculator.com handles. Last updated 3 November 2026.

Calculations

The numbers you type into a calculator are processed in your browser. They are not sent to us or stored.

Visitor statistics

We count visits 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. It sets no cookies and builds no profile of you. The statistics are not shared with or 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. We do not add you to any mailing list.

Cookies and advertising

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

Your choices

You can ask us to delete any message you sent by writing to info@this-calculator.com. Browser settings let you clear local storage at any time.
