Privacy Policy

The calculator runs locally and does not submit the birth dates you enter to a calculator database.

Information processed by the calculator

Dates entered into the calculator remain in your browser. We do not operate accounts or a database for calculator entries. When you choose to share a result, dates are added to the link so another browser can reproduce it; do not share that link if you consider a birth date sensitive.

Google Analytics

We use Google Analytics 4 to understand aggregate page usage, such as page views, browser and device information, and approximate geographic region. Google Analytics may use cookies or similar browser storage. We disable Google advertising signals and ad-personalization signals. The analytics page location is limited to the site origin and route, so birth-date query parameters in shared calculator links are excluded from the page-location value sent with analytics events.

Hosting and logs

Our hosting provider may process standard request data such as IP address, user agent, requested URL, and timestamps for security and service delivery. We do not sell calculator entries or use them for advertising profiles.

Your choices

You may use the site without entering a name, email address, or account information. You can restrict analytics cookies or third-party scripts through your browser settings or content-blocking tools. To ask a privacy question, email hello@arcanacalculator.net.
