## Overview

infoChecker is a small, single-file command-line utility. Its workflow gathers system details, network addresses, and browser-like headers, then formats and prints them locally. The graph separates those collection stages from the terminal presentation layer. The source shows optional psutil use and platform fallbacks; no data is sent to external servers. All implementation nodes point to the sole source file.

Main entry points: [`device_info.py`](https://github.com/dotvrtx/infochecker/blob/main/device_info.py) (CLI entry point)
