Privacy Policy
Effective: August 17, 2026
Calculator inputs stay in your browser
The calculator code runs locally in your browser. Values you enter are not sent to Tools for Machining, stored in an account, or retained in a calculation-history database. The site does not provide accounts or file uploads.
Information involved in a site visit
Like most websites, the hosting and network infrastructure may process ordinary technical request data needed to deliver and protect the site, such as an IP address, requested URL, timestamp, browser or device information, and security signals. Tools for Machining does not use that data to build calculator-input profiles.
External services
The site is delivered using Cloudflare Workers Static Assets. Cloudflare may process request and security data under its own terms and privacy practices. This site does not intentionally include advertising networks, third-party analytics, social tracking pixels, externally hosted fonts, payment processors, or AI APIs.
Browser storage
The current calculators do not intentionally save inputs in cookies, local storage, or an account. Your browser, extensions, network operator, or device may retain browsing information independently of this site.
Children and sensitive information
The service is a general technical utility and is not directed to children. Do not enter personal, confidential, export-controlled, or otherwise sensitive information into calculator fields.
Changes
This policy may be updated as the site changes. The effective date above identifies the published version. If a future feature changes data handling, this page should be updated to describe the actual behavior.
Questions
No operator contact details were supplied for publication. If a contact method is added to this website in the future, privacy questions may be directed through that published method.
