Build Physics analytics

The app can use PostHog to count a small set of anonymous product-usage events. Analytics are disabled unless the site operator supplies both required PostHog environment variables when creating the production build.

What may be collected

The app only sends these event names and limited non-personal categories:

• app opened and simulation started;
• the identifier of a selected preset or tutorial;
• tutorial completion and graph opening;
• the export format used for a world export.

What is not collected

The analytics code does not collect names, email addresses, school names, typed content, uploaded scene files, saved scene contents, object labels, exported data, or other personally identifiable information. Automatic click tracking, pageview tracking, session replay, surveys, and user profiles are disabled.

Anonymous operation

Analytics use an anonymous identifier held only in browser memory, are not persisted across visits, respect the browser's Do Not Track setting, and ask PostHog not to use IP addresses for analytics or geolocation. As with any web request, the analytics service may process basic network metadata to deliver the request.

Local app data

Saved scenes, display preferences, and tutorial progress are stored locally in the browser. They are used to restore the app on that device and are not sent through the anonymous analytics integration.
