Cookie Policy

Last updated August 30, 2026

Short version: this site works without advertising cookies, and we like it that way.

What we store in your browser

Local storage for your convenience: saved calculator scenarios and, for the length of your visit, any UTM campaign tags from the link you arrived on. This data stays on your device; we can't read your saved scenarios.
An admin session cookie — set only if you sign in to the site's administration area (i.e., you run the site). Visitors never receive it.

What we don't use

No advertising or cross-site tracking cookies;
No third-party analytics cookies — our minimal usage analytics are first-party and cookieless;
No social-media pixels.

Your controls

You can clear saved scenarios anytime by clearing your browser's site data for this domain; everything on the site keeps working (you'll just lose saved scenarios). We also honor Do Not Track and Global Privacy Control for our own analytics events.
