Working Offline

simpleTracker is built offline-first — your notes and tasks are always available, even when you don’t have internet.

How It Works

When you create, edit, or delete a note or task offline:

1. The change is saved locally to your device immediately
2. It’s added to a background sync queue (stored in IndexedDB)
3. When connectivity returns, all queued changes are synced to the server automatically

You don’t need to do anything — it just works.

What Works Offline

• ✅ Viewing all your notes and tasks
• ✅ Creating new notes and tasks
• ✅ Editing existing items
• ✅ Completing/uncompleting tasks and subtasks
• ✅ Deleting items

What Requires Internet

• ❌ Sharing notes or projects (these need real-time sync)
• ❌ First-time login
• ❌ Seeing changes made by collaborators on shared items

Sync Indicators

simpleTracker shows you when you have pending changes waiting to sync. Once connectivity is restored, syncing happens automatically via:

• The browser’s online event
• A 30-second background heartbeat check
• When you switch back to the app (visibility change)

Lie-fi Detection

Sometimes your phone shows “connected” but can’t actually reach anything (common on weak WiFi or congested cellular). simpleTracker detects this by pinging the actual backend — not just trusting navigator.onLine — so you’ll always know your true connectivity status.

Tips

• Non-shared items always work offline — plan around this if you’re about to go somewhere without service
• The app caches your data locally, so it loads instantly even on slow connections
• If you see a pending sync count, don’t worry — it will resolve automatically when you’re back online
