Privacy Policy

Calculator inputs stay on your device

Everything you type into a calculator — dimensions, prices, quantities — is processed entirely in your browser. We do not send calculator inputs to our servers, and we do not store them.

What we collect

We use Cloudflare Web Analytics, a privacy-first analytics service that does not use cookies, does not fingerprint devices, and does not track you across sites. It gives us aggregate page-view counts and performance metrics. We also record anonymous, aggregate usage events (for example, "a calculation was completed on the gravel calculator") that contain no personal information and none of your input values.

What we don't do

• No accounts, and no collection of names, emails, or phone numbers
• No advertising cookies or cross-site tracking
• No sale or sharing of personal data — we don't have any to sell
• No device fingerprinting

Hosting

This site is served by Cloudflare, which processes standard technical request data (such as IP addresses) to deliver and secure the site. See Cloudflare's privacy policy for details.

External links

Some pages link to external sites, including clearly labeled sponsored links. Their privacy practices are their own; this policy covers only toolertools.com.

Changes

If our practices change — for example, if we add advertising — we'll update this page and its date before the change takes effect.
