Privacy policy
What data is processed when you use CalcSmith — and, just as important, what is not. Last updated: November 2026.
Calculator data: none leaves your device
Every calculator on CalcSmith runs entirely in your browser with JavaScript. The figures you type are never transmitted to, stored on or logged by any server. There are no user accounts and no database of calculations. When you close the tab, the numbers cease to exist.
Data we collect
- Technical browsing data: IP address, browser type and pages visited, processed by our hosting provider for security and basic aggregate statistics.
- Email: if you write to our contact address, we process your message only to reply to you.
- Advertising: when the site displays ads, advertising providers may use cookies to personalize advertising, under their own policies.
Cookies
The calculators themselves need no cookies. The site may use technical cookies necessary for operation and, where applicable, third-party measurement and advertising cookies. You can block or delete cookies in your browser settings; all calculators will keep working.
Your rights
If you have emailed us, you can request access to, correction of or deletion of that correspondence by writing to the address on the contact page. We do not sell or share personal data with third parties for their marketing purposes.
