History stays in this browser on this exact origin (host and port). Closing or restarting the browser preserves it unless browser data is cleared, private mode is used, or storage is unavailable. Browser localStorage capacity is limited (often about 5 MB); keep JSON backups. Previous attempts are never evicted automatically. Audio bytes are not archived; replay needs your click and may need the original URL/network. Demo questions are synthetic practice content.
