What analytics receives

When analytics is on, we use Google Analytics 4 to understand how this calculator is used. It receives page views, generated-result counts, sharing methods, and downloads. A generated-result event includes the numeric ages and heights present in the two profiles, estimated game volume, target volume, fill/spill counts, the fictional game multiplier, and whether neither, one, or both aliases were supplied.

Alias text, ethnicity selections, full receipt links, and URL query strings or fragments are excluded from our analytics events. Profile values describe calculator scenarios; they are not verified personal measurements.

Google Analytics uses first-party cookies and a browser identifier to measure sessions and usage. Google also processes technical information such as browser/device details and approximate location. There is no login here, but analytics data is not automatically anonymous.

What stays in your link

Share links store the profiles and any aliases after the # in the URL. We do not keep a database of those links. Anyone you share a link with can read its contents. The receipt image is made in your browser.

Your choice

Google Analytics starts by default on the calculator and receipt pages, before you click a banner button. Accept saves the enabled preference. Customize lets you turn analytics off and save your choices. You can also change the setting on this page. Your choice is saved in this browser's local storage. Turning analytics off stops further analytics and clears this site's Google Analytics cookies; it keeps Google tags blocked on future visits. Data already sent is not removed by changing your choice.

We respect supported Global Privacy Control and Do Not Track browser signals. Advertising personalization and Google Signals are disabled in our tag configuration.
