2.9 How offline mode and data sync work

Helpie Event is designed for exhibition venues where WiFi is unreliable or unavailable. Here’s what works offline and what doesn’t.

Works fully offline

• Scanning business cards

• Entering interaction details manually

• Tapping through Data Modules (qualification)

• Adding text notes, photo notes, and voice notes

• Starring interactions

Your team can capture data all day without any internet connection.

Needs internet

• Badge scanning — fetches visitor details (email, phone) from the organiser’s server

• Sending follow-up emails and WhatsApp messages

• Syncing data to the server

• First-time login

What appears immediately vs what's fetched later depends on the event organiser.

Each organiser decides what data is encoded in the badge QR code and what is stored on their server. At some events, you'll see company, name, and job title immediately. At others, you may see only a reference number.

Helpie fetches the remaining details (which may include email and phone) from the organiser's server in the background. This requires an internet connection. If connectivity is poor, Helpie keeps trying until it succeeds.

What details are available at all — and how quickly — is determined by the organiser's privacy policy and technical setup, not by Helpie.

How sync works

The app syncs data to the server automatically, approximately every 5 minutes. You don’t need to do anything — it happens in the background as long as the app is open and there’s some connectivity.

For extra assurance, you can manually trigger a sync:

• Tap the Sync Now button in the app’s menu.

Pro tip: Good practice: tap Sync Now at the end of each exhibition day to make sure everything is uploaded.

What happens if the phone dies?

All data captured in the app is saved locally on the device first. If the phone battery dies or the app crashes, your data isn’t lost.

When the phone restarts and the user logs back in, the app syncs all locally stored data to the server automatically.
