Information entered into the calculator
The calculator is designed to calculate in your browser. Do not enter a street address or other personal information; the tool does not need it. Calculation inputs are not placed in the page URL. This project does not currently configure an analytics provider, advertising tracker, account system, or email collection form.
Hosting and server logs
The website host may process technical request data, such as IP address, browser and requested page, to deliver and secure the site. Hosting is provided by Cloudflare. See the hosting provider privacy policy for its data practices.
Cookies and third parties
The calculator does not require cookies to perform calculations. External links on the sources page open third-party websites that have their own privacy practices. No claim is made here about those sites.
