Privacy and analytics

Key points

Calculation input is processed in your browser.

• Data for analytics and ads is separate from your calculator inputs.
• Calculation form values are not sent to GA4 or to any HibiCalc backend.

Inputs and calculation results

• Each calculator reads form values in browser-side JavaScript and displays results immediately on the page.
• Normal page requests, GA4 events, and AdSense ad requests are still triggered while viewing the site.
• Do not post entered numbers or sensitive life information in screenshots or issue reports.

Google Analytics

• Main event fields include path, page title, calculator ID, and search term.

• Google Privacy Policy

Google AdSense

• Pages include the AdSense JavaScript loader for ad display.
