What stays on your device
The calculator temporarily stores the birth date in your browser’s session storage so the result page can open. Closing the browser tab or session clears it according to your browser’s normal session-storage behavior. Arcana Within has no account system or server-side birth-date storage.
Anonymous usage measurement
This site uses Google Analytics 4 to understand basic page use and anonymous product interactions. The site may record page views, a successful calculation, and interest in the coming-soon deeper report.
Analytics events must not include your birth date, card result, name, report text, email address, or free-form text. Google may process technical information such as browser, device category, approximate location derived from network information, and referring page under its own terms.
Cookies and controls
Google Analytics may use browser storage or cookies. You can block analytics with browser privacy controls, content blockers, or JavaScript settings; the core calculation runs locally and does not require an account. The site owner also uses a browser-local exclusion during maintenance and testing so those visits are not counted.
