Storage Health

FlashBoards stores your media locally in the browser. The Storage Health tab helps you monitor usage and clean up unused data.

How To Access

Open Settings (gear icon) and select the Health tab in the sidebar.

Storage Health tab in Settings showing localStorage and IndexedDB usage

What It Shows

  • 1localStorage — Board data, settings, models, and workflows. Limited to ~5 MB by the browser.
  • 2IndexedDB — Media blobs, image cache, and video thumbnails. Much larger limit (typically hundreds of MB to several GB).
  • 3Per-board usage — Expand to see how much media each board consumes. Computed on-demand.
  • 4Memory caches — In-memory caches for images, video thumbnails, and audio waveforms. Cleared on page reload.

Orphan Analyzer

Over time, media blobs can become orphaned — stored in IndexedDB but no longer referenced by any board. This can happen when you delete items or after failed generations.

Click Analyze to find orphaned blobs, then Clean Up to delete them and free space. The analyzer re-checks references before deleting to prevent accidental data loss.

Quick Actions

  • 1Clear Image Cache — Frees memory from cached browser images. Images will reload from IndexedDB as needed.
  • 2Clear Thumbnails — Removes cached video thumbnails from IndexedDB. Thumbnails will regenerate on next view.
