The calculator runs in your browser. This site does not send the numbers you enter to an application database, and it does not embed advertising pixels, analytics scripts or third-party fonts.

The hosting provider may process ordinary request information to serve and protect this website. Its own policies apply. External websites linked from these pages have their own privacy practices.

The downloadable toolkit can save estimates and job records in browser storage on your device. This is not cloud storage, and other people using that browser profile may be able to access it. Exported files are under your control. Avoid entering sensitive client details you do not need.
