This site is a small public web app. It does not require an account, and normal calculator use is designed to stay in the browser after the page loads.

The calculator supports age ranges 18 and above only. Shared links and restored states are kept within that supported range.

The app may store a small amount of browser state that is necessary for the site to work properly, such as routing state or shareable calculator settings in the URL.

For the initial public launch, optional analytics and advertising are off, and the site does not show a live privacy-preferences panel because there is nothing optional to opt into.

During normal use, the live calculator logic runs client-side in the browser after the page loads.

The server may still deliver the page, metadata, and normalized datasets needed to run the app, but ordinary filtering does not require an account or a user profile.

A share link is only created when you explicitly use the sharing controls.

Those links carry the calculator state so the same result can be reopened later. If you do not use sharing, there is no separate share record created just from using the calculator.

This launch does not intentionally turn on optional analytics cookies, advertising cookies, or ad-network scripts.

If the site later adds optional analytics or ads, this page should be updated to explain what changes and what choices visitors have.

Analytics active right now: no.

Advertising active right now: no.

Privacy questions can be directed through the site's published contact channel when one is available.

This page may be updated as the site changes. If analytics, advertising, or other storage behavior are introduced later, the privacy notes should be updated to reflect that.
