Analytics
With your permission, Google Analytics 4 helps us understand visits and calculator usage. It may process device and browser information, approximate location, pages viewed, interactions, referrer information, and identifiers such as the _ga cookie. We use this information to operate and improve the site.
You can accept or decline analytics in the banner and reopen your choice through “Cookie settings” in the footer. You can also use the Google Analytics opt-out browser add-on. See Google’s Privacy Policy.

Storage and retention
We store your analytics preference in your browser’s local storage under bch-cookie-consent. Google Analytics and Cloudflare apply their own retention practices. Email correspondence is kept only as reasonably needed to answer, maintain records, prevent abuse, or meet legal obligations.
