Privacy Policy

Summary
The values you type into our calculators are processed in your browser and are not sent to us. We use cookies for advertising and to remember your unit preference.
Information we collect
We do not ask you to create an account. If you email us, we receive your email address and message and use them only to reply. Our hosting and security provider (Cloudflare) may keep standard server logs, such as IP address, browser type and pages visited, for security and performance.
Calculator inputs
Calculations run in your browser. Your unit choice (imperial or metric) is stored in your browser's local storage so the site remembers it. You can clear it at any time in your browser settings.

You can opt out of personalized advertising in Google Ads Settings, and opt out of some third-party vendors' cookies at aboutads.info. Read more in how Google uses information from sites that use its services.
Visitors in the EEA, UK and Switzerland
Where required, we ask for your consent before personalized ads or non-essential cookies are used, through a consent message certified under Google's requirements. You can change your choice at any time from the privacy settings link shown with that message.
