Calculator inputs and customer estimates
Calculations run in your browser. This site does not save calculator inputs in an account or database. Inputs remain in the open page; printing uses your browser’s print function. Avoid entering sensitive customer information in free-text fields.
The hosting provider may process technical request data to deliver and protect the site. We have not verified its log retention period, so this notice does not claim that hosting creates no records.
Optional email requests
Email delivery is currently a demo. Submitting the demo does not send an email address or quote to an email service and does not save them. It does not subscribe you to a mailing list. The address you type remains in the open page until you clear it or leave.
Results and printing remain available without email. Before a live email service is introduced, this notice must identify the service and its retention and deletion process. We do not promise a retention period for a provider that has not been selected.
Usage analytics
Google Analytics is configured for this build to measure page visits and the actions described below.
Action events identify the calculator or page, action, button placement, vendor and whether a link is official or affiliate. They exclude email addresses, customer names, entered job details, quote values, cost and profit amounts. A calculator-to-software link may include the calculator’s page identifier; it contains no entered quote data.
If Google Analytics is enabled, Google may process technical information such as browser and device information and use cookies. Page addresses passed by this integration omit query strings and fragments. Analytics consent and account settings must be reviewed for the audience before enabling collection. See Google’s data collection information.
Links to other services
Vendor and affiliate destinations operate under their own privacy notices. An affiliate service may record a referral or use cookies after you follow its link. This site does not control those services.
For privacy questions or requests, use the channel listed on the contact page. This notice describes the current site and is not a claim of compliance with every jurisdiction’s privacy requirements.
