Clear data practices for a planning tool.
This page describes Home Cost Signal as implemented. It does not claim that hosting and analytics create no data.
Calculator inputs and estimates
Calculator inputs are processed in the application to produce the estimate shown in your browser. Home Cost Signal does not provide an account or saved-estimate feature, and it does not intentionally store completed estimates in an application database. Copy and print actions use your browser.
Hosting logs
Home Cost Signal is hosted by Vercel. Vercel may process basic request, device, network, security, and diagnostic information in server and platform logs to deliver and protect the service. Retention and access are subject to the hosting configuration and provider practices.
Optional analytics
If a GA4 measurement ID is configured, Home Cost Signal can send approved product events such as calculator steps, estimate completion, copy, print, methodology views, and source-link opens. Events use broad properties such as input method, material category, resolution level, and confidence label. The analytics code is designed not to send raw ZIP codes, exact home size, exact estimate totals, email addresses, or fingerprinting data.
GA4 may use browser identifiers or cookies according to Google's implementation and the visitor's browser settings. When the measurement ID is not configured, this analytics integration does not load.
Contact requests
If a public contact email is configured and you choose to send a message, the email provider and recipient process the information you include. Do not send sensitive financial, insurance, identity, or property records.
Third parties, retention, and choices
Vercel hosts Home Cost Signal, and Google is the only optional analytics provider prepared in this implementation. Their own retention practices may apply. You can limit analytics identifiers with browser privacy controls, cookie settings, content blockers, or by declining to use an optional contact channel. Because the service has no account or saved-estimate database, there is no account profile to delete.
Changes
This disclosure should be updated if storage, analytics, contact, or other data practices change. Last updated July 17, 2026.
