Calculator data
Dimensions, ZIP codes, pricing, quote references and density values are processed in your browser. When you open a ZIP-specific supplier or search link, that third party receives your ZIP and, for supplier searches, the selected material. Its privacy practices apply. This version does not send calculator inputs to an application database, use analytics or store calculator values in cookies or local storage. Google advertising code is loaded separately as described below. Downloaded plan files stay wherever you save them. Shared plan links encode your inputs in the URL fragment; anyone with the link can read those inputs. Loading a plan reads its data locally in your browser.
Hosting
The hosting service may process network requests and technical information needed to serve the website. Browser-side calculation does not mean that visiting a hosted website produces no server logs.
