Privacy / Initial version

A simple site.
A small footprint.

This version contains no advertising, analytics scripts, forms, accounts or newsletter sign-ups. It does not set application cookies or save calculator inputs to browser storage.

The message calculator processes the values in your browser. Its code does not send those values to a server.

The hosting provider processes web requests to deliver the site and may process technical information such as IP addresses and request logs under its own policies. When hosted on Cloudflare, see Cloudflare’s privacy policy (opens in a new tab).

External source links take you to websites with their own privacy practices. This page will need updating if features such as analytics, advertising or contact forms are added.
