Google Analytics runs automatically to help us understand which public Wonders and explorer tools are useful, unless you turn it off or your browser requests no tracking. Google receives a browser identifier, sanitized page locations and allowlisted interaction events. Google may also receive network information such as your IP address when your browser contacts its service.

For signed-in members with analytics enabled, CodexMira associates that browser identifier with verified purchase, credit and billing outcomes so renewals and automatic top-ups can be measured without an open browser. Card details, email addresses, chat questions and answers, personal saved labels, and raw error messages are not included in these analytics events. Advertising features are disabled.

You can turn analytics off here. Turning it off stops new Google tracking, clears Google Analytics cookies on this site and asks the server to revoke the member analytics association. Already-collected reports cannot be removed by clearing browser cookies. Necessary sign-in, payment and operational records remain separate from analytics.

Replit manages its own published-site hosting tracker; this choice also controls the custom events CodexMira sends to that tracker, but does not change Replit's platform publishing settings.
