### 1. Information Collection and Use
#### Local USB & Serial Communication
- The App interfaces directly with connected USB-to-Serial devices (e.g., FTDI, Prolific, CH340, CP2102, Arduino) via USB OTG.

#### Third-Party Services (Google AdMob)
The App displays advertisements powered by Google AdMob. To serve relevant ads and prevent fraud, Google Mobile Ads SDK may automatically collect certain device information, including:

- Advertising ID (Google Play Services ID)
- Device model, operating system version, and general network information
- Diagnostic and performance logs
