This course has no account and no database. Carry progress as transparent JSON, or merge two open devices directly over an encrypted nearby connection.
Export lessons, attempts, lab settings, journal entries, and preferences. Download or copy the same transparent JSON. File and pasted-text imports are validated before they can change this device.
Erases local progress, attempts, lab state, journal entries, and settings. Export first if you might need them later.
Scan or manually exchange two connection tokens, verify the same pairing phrase, then merge progress over an encrypted WebRTC channel. Both devices must stay open on the same local network. No account or sync server is used.
