What Happens Offline

Filament is designed to stay usable when you are temporarily offline, but activation still requires a successful online round-trip at least once.

First activation

You cannot activate a brand-new machine without network access. The app needs to send the key to Filament's backend and receive a signed receipt.

After a successful activation

Once Filament has a valid signed receipt, the app can launch offline and continue in a licensed stale/offline state.

That means:

• the app stays unlocked
• your projects remain available
• export stays available
• Filament waits to refresh the license state the next time it can reach the backend

What can cause a downgrade later

When Filament gets back online, it may downgrade the app if:

• the license was revoked
• the license expired
• the activation no longer exists
• the stored receipt no longer matches the machine/install identity

If that happens, Filament falls back to trial behavior and shows the change in the desktop UI.

Offline is not a permanent bypass

Offline launches are a deliberate resilience feature, not a promise that a revoked license will stay unlocked forever. The next successful online validation can update the local state.
