Privacy Policy

Last updated: August 23, 2026

Calculators run entirely in your browser — the numbers you enter into a calculator are not sent to or stored on any server, and this site does not intentionally send calculator input values to Google Analytics.

CartEconomics uses Google Analytics 4 to understand, in aggregate, how visitors use the site — which pages are viewed and general traffic patterns. This can involve general usage information such as pages visited, approximate location (typically city or region level, derived from IP address), and device or browser type.

Analytics only loads after you actively accept it in the consent banner shown on your first visit. If you decline, or close the banner without choosing, the Google Analytics tag is never loaded and no analytics data is sent. Your choice is saved in your browser so you aren't asked again on later visits.

You can change your choice at any time using the Analytics preferences link in the site footer. It clears your saved choice and shows the consent banner again, so you can accept or decline afresh.

Any data collected through Google Analytics is handled under Google's own privacy policies, not this site's — see Google's privacy information for details on what Google collects and how long it retains data. We don't control or make guarantees about Google's retention periods.

This page describes what this site technically does. It is not a claim of compliance with any specific privacy law or regulation.
