Your numbers stay yours.
This page describes the calculator as currently built. Last updated: 12 October 2026.
Calculator inputs
Your dimensions, quantities and prices are calculated in your browser. The calculator does not send them to a calculation server, save them to an account or store them in browser storage. Reloading the page restores the example values.
Copying and printing
“Copy estimate” writes the displayed estimate to your device’s clipboard when you click it. “Print” opens your browser’s print dialog. What you do with a copied or printed estimate is under your control.
Hosting and access
The hosting provider may process ordinary connection and access information, such as IP addresses, browser information and request logs, to deliver and protect the site. A private preview may require authentication managed by the hosting provider. The calculator itself does not read your account details.
Analytics, advertising and cookies
The current calculator includes no advertising scripts, analytics tools or calculator-set cookies. If these are added, this notice must be updated and any required consent controls put in place before they are enabled.
