YOUR NUMBERS STAY WITH YOU

Privacy.

The calculator runs in your browser. There is no account and no job-upload service in this version.

Drafts and saved jobs

Inputs, including any business or customer details you enter, are stored in this browser’s local storage. They are not sent to an application server or synced to other devices. Use Start blank to replace the current draft, and remove saved copies individually. Clearing site data in your browser removes all local drafts and saved jobs.

Exports and clipboard

CSV exports and customer quotes are generated on your device. Copy text uses the system clipboard when you click the button. Print / save PDF opens your browser’s print dialog. Review exported files before sharing them.

Hosting and external sites

The hosting provider may process ordinary request information such as IP addresses and access logs to serve and secure the site. If you follow a reference link, that website applies its own privacy practices.

Advertising and analytics

This build has no advertising, affiliate tracking or analytics scripts. There are no third-party fonts or image requests. This notice must be reviewed before those services are added.
