FlashBoards stores workspace files locally in your browser. This keeps your work private and responsive, but local files depend on your browser data staying available.
Files you add and manage in your workspace are stored in this browser on this device.
If you clear browser data, delete site storage, use a private browsing session, or switch to another browser or device, those local files may no longer be available.
When local media storage starts, FlashBoards asks your browser to protect that data from automatic cleanup. If the browser denies that request, we show the info notification: "Browser storage may not persist between sessions."
This does not mean your files are already lost. It means the browser may clear site data later under storage pressure or browser policy.
Chrome and Edge decide this automatically. There is no direct switch that guarantees your site will be marked as fully protected.
You can still reduce eviction risk by allowing site data for FlashBoards:
Even after this, FlashBoards may still show the info message in some cases. That can be normal in Chrome/Edge, and the allowlist still helps.
Firefox typically asks directly when a site requests persistent storage.
Safari does not provide the same persistent-storage flow. Site data can be cleared based on browser policy, especially for inactive sites.
1. Keep using FlashBoards normally. This notification is preventive.
2. Apply the browser steps above (especially Chrome/Edge site data allowlist).
3. For important work, use backup tools regularly:
4. Cloud sync is in progress and will become the primary protection path once fully available in production.
