The planning checklist uses local storage. Its reset control clears the selected items. Clearing browser site data also removes them, and blocking storage can stop them surviving a reload.
Temporary calculations
The cost worksheet works in the open page. Its inputs are not a quote request and are not written to the contact record. Platform tabs similarly change only the visible guidance.
Locally served resources
The site loads its fonts, images and interface code from its own files. There are no advertising pixels or remote social embeds. Previously submitted enquiries remain separate from browser storage.
