Data Management & Privacy

Save, restore, export, and clear the data kept in your browser.

Open in Fuel Lens ↗

Fuel Lens can save the current dataset and settings in browser storage. Storage is local to the browser profile and device.

Available actions

  • Save data to browser
  • Load a saved snapshot
  • Export a full backup
  • Import data, settings, or a full backup
  • Clear data and settings

Storage and migration

Fuel Lens keeps the large serving history in IndexedDB and the smaller dashboard state in a separate persisted store. The dashboard can hydrate core values first while Foods and serving details load in the background; the complete serving history is still retained.

Older browser snapshots are migrated through visible Reading data, Converting, Validating, and Ready phases. Do not close the tab during migration. If migration fails, use the offered backup download before retrying.

Backups

Use Export before clearing browser data or moving to another device. Importing a snapshot replaces the corresponding current data, so confirm the overwrite prompt carefully.

Privacy boundary

Production analysis is client-side. Treat exported backup and AI-context files as sensitive because they contain the data you selected.
