Calculator inputs

Calculations run in your browser. This application does not send your measurements, prices, or project names to an application server.

Saved projects

When you select Save project, the result and inputs are stored in your browser’s local storage. You can remove individual projects on the Saved projects page, or remove all stored projects through your browser’s site-data settings. Other people using the same browser profile may be able to see them.

Hosting and fonts

The hosting provider may process request data, such as IP addresses and browser information, to serve and secure the website. This site requests fonts from Google Fonts, which receives the network information needed to deliver them. Your browser can use fallback fonts if those requests are blocked.

Advertising and analytics

This version does not include advertising or analytics scripts. If advertising or analytics is added, this notice and any required consent controls should be updated before activation.
