Calculator information stays on your device
The calculators run in your browser. Values you type into calculator fields are used by JavaScript on your device to produce results. The site does not provide accounts, project storage, file uploads, or a database, and calculator entries are not intentionally transmitted to us.
Do not treat browser-local processing as a guarantee that your device, browser, network, or installed extensions are secure. Anyone with access to your screen or device may be able to see the values you enter.
Ordinary hosting data
Like most websites, the static hosting and network providers that deliver the site may process technical request information such as IP address, request time, requested URL, browser or device information, referring page, and security or diagnostic events. This information may be needed to deliver the site, prevent abuse, and maintain reliability. Their handling is governed by their own terms and policies.
Cookies, analytics, and advertising
The site does not intentionally set advertising cookies, run behavioral advertising, or include a site analytics service. If that changes, this policy should be updated before those services are enabled. Your browser or infrastructure providers may still use essential storage or network mechanisms outside the site operator’s control.
External links
The site may link to third-party resources. Visiting another site makes your interaction subject to that site’s privacy practices. A link does not imply endorsement, certification, or partnership.
Children and sensitive information
The tools are intended for general trade and project-planning use, not for collecting personal information from children. Avoid entering personal, confidential, regulated, or customer-identifying information into calculator labels or fields.
Changes and questions
This policy may be revised as the site changes. The date above identifies the current version. No operator contact details have been supplied for publication; do not send sensitive information through unrelated channels or third-party listings claiming to represent this site.
