Who runs this site

This site is run by Calculator Mine ("we", "us"). Questions about this policy: use the message form on our Contact page.

Information we collect

• Calculator inputs: none. Calculations run in your browser and your numbers are not sent to us or saved. If you copy a Share Results link, your inputs are part of that link, and anyone you send it to can see them.
• Messages you send through the contact form: your name, email address (so we can reply), topic and message.
• Technical data: like most websites, our hosting provider automatically records basic information such as IP address, browser type and pages requested, to keep the site secure and running.
• Advertising data: our advertising partner Google uses cookies and similar technologies, as described below.

You can opt out of personalized advertising by visiting Google Ads Settings (adssettings.google.com), or opt out of some third-party vendors' use of cookies for personalized advertising at aboutads.info/choices.
