## When to read this
You expect intermittent connectivity (mountains, cellars, roaming). The guest app is built to keep working offline as long as the initial sync completed.

## What stays available offline
- Event feed (latest 250 photos) and album structure.
- Upload rules (size limits, moderation settings).
- Draft achievements and stickers.
- Help center excerpt (top 10 articles per locale) if you opened Help at least once online.

## Offline workflow
1. **Capture as usual.** Everything stores in the encrypted local queue.
2. **Review pending uploads.** Look for the grey *Queued* label. Add tags/notes even while offline.
3. **Monitor storage.** The banner warns if device storage drops below 500 MB; delete sent items or transfer to another device.
4. **Reconnect briefly.** Once any network is available, open Fotospiel. Sync restarts automatically, prioritizing oldest items.
5. **Confirm completion.** A green toast “All uploads delivered” appears and the queue counter returns to zero.

## Troubleshooting
- **Stuck in “Queued” despite coverage?** Toggle airplane mode off/on, then reopen the app to reset the service worker.
- **Different devices?** Offline queues stay on the original device; there’s no cross-device merge.
- **Battery saver** might pause background sync. Keep the app in the foreground for large batches.
