Privacy policy
The short version: calculator entries and selected G-code files are processed in your browser and are not sent to us.
Browser-local calculations and files
Calculator values are processed by code running on your device. The local G-code analyzer reads the file you select within the browser tab. The site has no account system, database, file-upload endpoint, or saved calculation history. Closing or reloading the page clears the displayed result unless your browser independently retains form state.
Ordinary web delivery
The static site is delivered using Cloudflare Workers Static Assets. Like other web hosts and network providers, Cloudflare may process technical request data needed to deliver and protect the service, such as IP address, request time, requested URL, user-agent information, and security signals. Their handling is governed by their own terms and policies.
Cookies, analytics, and advertising
This implementation does not set analytics or advertising cookies, embed ad networks, or include third-party analytics. The site may still be subject to essential network-level processing by its hosting provider.
Your choices
You can use the numeric calculators without providing personal information. Do not select a G-code file containing information you do not want processed on your own device. Browser controls can clear locally retained page data.
Changes and questions
This policy may be updated when the site’s actual operation changes. No operator contact details have been supplied for publication; this policy does not invent an identity or address.
