Your offline event checklist

Prepare each collection device before you leave a reliable connection.

Before the event

Charge devices, arrange power and sign in while online. Load the forms and collections you need on every device. Check account permissions, plan capacity, required fields and any link expiry. Keep form changes out of the last-minute setup window where possible.

Run a realistic test

Disconnect a prepared device, complete a test response, reconnect and confirm the record has reached the server. Check uploaded files as well as answers. Repeat on each browser or device type you intend to use.

While collecting

Keep the prepared app available and monitor pending synchronisation. A response waiting on one offline device will not yet appear on another. Do not clear site data, uninstall the app or assume an email receipt has been sent while disconnected.

Before packing away

Reconnect every device and confirm that pending records and media have synchronised. Review records from another connected device where possible. Only clear local data after you have confirmed that nothing remains pending.

Keep a fallback

Offline capability does not protect against a lost device, exhausted battery or browser-storage loss. Decide how staff will pause collection or use an approved fallback, and how those records will be reconciled afterwards.
