Local processing
Workbook bytes are read by the browser and Web Worker. No API route, upload endpoint, account, cloud storage, analytics, or AI service is part of the audit workflow.
MODELGUARD / PRIVACY
Privacy and security
The default workflow is local, ephemeral, and inspectable.
Ephemeral session
ModelGuard keeps parsed workbook data in memory for the current tab. Closing or clearing the workspace releases the references.
Safe exports
Exports are created locally. CSV formula cells are escaped to reduce spreadsheet formula injection when a reviewer opens the file.
