Privacy, explained.

Edition date: September 13, 2026.

Calculator inputs

The calculator processes your entries within your browser. This site does not send those entries to a server, save them to browser storage or attach them to a user account. If you choose to create a scenario link, its fragment contains your calculator values. Anyone with that link can read them; fragments are not sent as part of the HTTP request. The browser may retain opened URLs in its history. Reloading restores the default example unless the URL contains a scenario you chose to open.

Cookies and tracking

This edition does not set cookies or load advertising, analytics, third-party fonts, embedded videos or tracking pixels. It has no newsletter form, comments, checkout or account registration.

Local use and hosting

When you open the downloaded pages directly on your computer, the site does not need a hosting service to display its content. If accessed through a web server, that server may record ordinary request information such as IP address, requested page and timestamp. The public website is hosted on Cloudflare Pages. Cloudflare processes request information to deliver and protect the website, including IP addresses and technical request data. Its processing and retention practices are described in the Cloudflare Privacy Policy. We have not enabled advertising or visitor analytics scripts.

External links

Links to sources take you to other organizations’ websites. Those organizations handle information under their own policies. The pages do not contact those sources merely to display the links.

If an email address is available and you choose to send a message, your email provider and the receiving email service process it. Avoid including sensitive information.

Future changes

If advertising, analytics, forms or other services are added, this notice will be revised to describe them. Relevant privacy choices will be made available before those services are activated.
