The Delusion Calculator performs all calculations entirely in your browser. We do not collect, store, or transmit any of the preferences or criteria you enter into the calculator. Your filter selections never leave your device.
We may use standard web analytics tools (such as Google Analytics) to understand general traffic patterns, including page views, geographic regions, and device types. This data is aggregated and does not identify individual users or their calculator inputs.
Our site may use cookies for basic functionality and analytics. You can control cookie settings through your browser preferences.
Our Sources page contains links to external websites (census bureaus, research organizations, etc.). We are not responsible for the privacy practices of these external sites.
Since we do not collect personal calculator data, there is no personal data at risk. All calculations happen client-side in your browser using JavaScript.
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
