Draft inputs stored in the browser
Project progress, including the current wizard step, selected inputs, pour date, and ZIP code, is saved in local browser storage so the draft can be restored after a refresh or return visit. Drafts are kept separately for each calculator route.
Weather and location lookups
The ZIP code may be sent to public geolocation and weather services to resolve state, planning context, and forecast data. Fetched weather forecasts and calculated result objects are not stored; results are recalculated from the saved inputs.
Share links
Share links encode selected project inputs in the URL fragment and take priority over a saved draft when opened. They do not include fetched weather forecasts or checklist state.
Analytics and behavior tools
This site uses Google Analytics to collect aggregated page-view and usage statistics, and Microsoft Clarity, a behavioral analytics service that records page interactions such as clicks, scrolls, session replays, and heatmaps to help improve the calculator experience.
These services may set cookies and transmit usage data to Google and Microsoft. See Google's privacy policy and Microsoft's privacy statement for details on how that data is handled.
