Privacy / Initial configuration

The model stays
in your browser.

Stackrange does not upload the dimensions, labels, criterion or calculated report to a calculation service.

Updated 18 October 2026. This notice describes the initially prepared host configuration.

Working inputs

The calculator keeps values in page memory. Its code uses no account, database, cookie, localStorage or sessionStorage. Restoring the example, reloading or closing the page can discard entries. Browser form restoration and history are separate features controlled by your browser.

Clipboard and downloads

Copy asks the browser to write the requested local report to your clipboard. Text and CSV downloads are created locally. No export is uploaded by this tool. Clipboard contents and downloaded files can remain on your device until you remove or replace them.

Hosting requests

Cloudflare Pages delivers the site. Ordinary page and asset requests can expose IP/network information, request times, URLs and browser details to hosting and security providers. Calculator inputs are not deliberately attached to request URLs. Local calculation does not mean infrastructure keeps no request logs. See Cloudflare's privacy policy for its practices.

Analytics, advertising and consent

No active analytics, advertising or consent-management loader is included in this initial release, and no automatic analytics integration is expected until separately enabled for this host. Google owner metadata, publisher metadata and ads.txt prepare identification only. They do not establish ownership verification, traffic, advertising approval or ad serving. Actual later service configuration requires truthful updated disclosures and any required consent controls.

Contact email

The contact address is an existing public forwarding alias shared with Yardfill and other portfolio tools. Email passes through your email provider, SimpleLogin forwarding and the owner's email provider. Those providers and the owner receive your sender details, message and ordinary email metadata. Send only what is needed for the enquiry. Opening the contact page alone does not submit an address or message.

External links

Reference and policy pages are opened only when you choose their links. They follow their own practices. No external font, media embed, CAD service or calculation API is needed. Use the shared contact address for a privacy enquiry.
