Privacy Policy
What this site collects, what it does not, how on-site search works entirely in your browser, and which hosting records exist for ordinary requests.
4 Building Materials is published as a static site. It does not run accounts or advertising pixels, and it does not set cookies of its own. We use a self-hosted Umami instance for cookie-free, anonymous visit statistics (pages viewed, referrer, browser and country); it sets no cookies and does not track you across sites.
Hosting records
Pages are served from a content delivery network, which produces ordinary request records such as IP address, timestamp, requested URL, and user agent. These are operational logs held by the hosting provider for delivery, security, and abuse handling; they are not used to build a profile of you.
On-site search
Search runs entirely in your browser against a static JSON index downloaded with the page. Your query is not sent to an application server. Requests for the search page and the index file appear in hosting logs like any other file request.
Outbound links
Guides link to standards bodies, manufacturers, and other publishers. Those sites operate under their own privacy terms, which we do not control.
Changes
If a newsletter processor, advertising, or any form that collects personal data is added to this site, this page will be updated before that feature goes live, along with the retention periods and processors involved.
