Calculations on your device
All calculator arithmetic and CSV creation happen in your browser. We do not upload your measurements or printed material lists. Form values are kept in page memory and reset when the page is reloaded or closed.
No tracking scripts
This version has no analytics, advertising, tracking cookies or account system. It does not use local storage to save your projects. There are no external font or image services.
Hosting requests
Your hosting provider receives normal requests to serve the website, including information such as an IP address and browser headers. Its access logs and retention are governed by the provider. Browser printing and files you save are handled by your device.
Changes to the website
If analytics, advertising, accounts or uploads are introduced later, this page must be updated before those features are enabled.
