## WeakSim Description
WeakSim is an iOS weak network simulator. It intercepts device traffic through the system VPN (Packet Tunnel), applying delays, packet loss, bandwidth throttling and other impairments to TCP/UDP packets locally. It reproduces real-world weak network scenarios such as subways, elevators, high-speed trains, and poor signal areas, helping you verify your app's timeout, reconnection, and degradation logic.

Core Features:
- System-level traffic interception: Based on Network Extension Packet Tunnel, all device traffic goes through weak network simulation.
- 9 built-in preset scenarios: 2G / 3G / Weak 4G / Weak Wi-Fi, Subway, Elevator, High Latency, High-Speed Train Disconnection, DNS Timeout.
- Customizable network impairment parameters: Latency & Jitter, Packet Loss, Up/Down Bandwidth Throttling, Reordering, Duplication, Tampering, Periodic Disconnection, DNS Failure / Timeout / Error / Domain Hijacking.
- Multiple network impairment models: Latency supports Uniform / Gaussian / Long-tail distribution; Packet Loss supports Random / Burst mode, closer to real link fluctuation.

Sensitive Data:
- WeakSim does not capture network packets; it only applies impairments such as latency, packet loss, and bandwidth throttling to network packets.
- WeakSim collects metrics such as the number of uplink and downlink packets, traffic volume, and packet loss count, and stores them locally using SQLite without involving any remote servers.
