Cookie Policy

Last updated September 7, 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.
Google Analytics cookies (_ga and _ga_*, up to two years) — used only to tell returning visitors from new ones and to count page views. Advertising features and Google Signals are turned off, so these cookies are not used to build an advertising profile of you. They are not set at all if your browser sends Do Not Track or Global Privacy Control.
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 analytics beyond Google Analytics and our own cookieless, first-party funnel events;
No social-media pixels.

Your controls

You can clear saved scenarios and analytics cookies anytime by clearing your browser's site data for this domain; everything on the site keeps working (you'll just lose saved scenarios). Turning on Do Not Track or Global Privacy Control in your browser stops both our own analytics events and Google Analytics from loading. You can also use Google's opt-out browser add-on.
