Privacy and accessibility

Anonymous by design

The app stores an anonymous random session ID on this device. It does not ask for names, email addresses, exact birth dates, precise addresses, employers, schools, health information, or precise location.

Survey fields are voluntary and broad. Demographic responses are never sent to Google Analytics and are shown only as aggregate dashboard data.

Google Analytics is not loaded unless you accept analytics. Declining analytics does not block the educational experience.

Accessibility support

The app uses semantic headings, visible focus states, keyboard-accessible controls, reduced-motion behavior, high-contrast text, and static fallbacks for 3D content.
