Data & offline

Backup and recovery

JSON preserves reading, quizzes, attempts, drill evidence, case entries and drafts. CSV is a report, not a restorable backup. Data is not encrypted or synced.

Use the original-data download if a stored record is damaged or from a future version. Keep it for recovery; this application does not silently erase it.

Choose a file to validate and preview. Nothing is replaced until you confirm.

Offline readiness

The footer reports whether this release is cached. Keep the first visit online until it says ready. Offline support needs localhost or HTTPS and browser storage. Downloading or exporting your record is separate from caching the course.

Public-site and localhost records belong to different origins. Move a record deliberately using JSON export and restore.

Clear this browser’s learner data

This removes progress, attempts, case entries and drafts on this origin. It does not delete downloaded files or uninstall the offline course.
