How SafeOrbit360 Handles Data When the Device Goes Offline

A monitoring platform is only as good as its data completeness. If gaps appear every time a device enters a basement, drives through a tunnel, or enters an area with poor signal — the data becomes unreliable for its most critical use cases.

The Problem: Connectivity Gaps Are Inevitable

In practice, every monitored device experiences connectivity gaps. Delivery drivers enter warehouses and underground facilities. Field workers operate in rural areas. Employees take the subway. Any monitoring system that relies on a live connection will have gaps in its data.

Our Solution: Offline-First Architecture

SafeOrbit360 uses an offline-first design — the agent collects and stores all data locally on the device, and syncs to the backend when connectivity is available. The backend is the destination, not the source of truth.

What Gets Stored Locally

The agent maintains a local SQLite database on the device that stores: GPS coordinates with timestamps (collected every 30 seconds when moving, every 5 minutes when stationary), call log entries as they occur, SMS records as they arrive or are sent, app usage events, and system events (battery alerts, SIM changes, etc.).

This database can hold up to 7 days of full data before the oldest records begin rolling off. In practice, we have never seen a real-world connectivity gap exceed 48 hours.

The Sync Engine

When connectivity is restored, the sync engine activates and uploads buffered data in chronological order. It uses a priority queue — SOS events and alerts are transmitted first, then recent location data, then older buffered records.

Data is uploaded in compressed batches of 500 records at a time. On a typical connection, a full 24-hour offline buffer (approximately 2,880 location points plus call logs) uploads in under 8 seconds.

Data Integrity

Each record is assigned a monotonically increasing sequence number when it is stored locally. When records arrive at the backend, they are inserted with their original timestamps — not the arrival time. This means the timeline view in your dashboard is always chronologically accurate, regardless of when the data was uploaded.

Duplicate records (which can occur if an upload is interrupted mid-batch) are deduplicated by sequence number at the backend. You will never see double entries in your dashboard.
