macOS Gatekeeper Note
Because PrepZero AI is distributed directly as an open-architecture binary without expensive Apple Developer notarization certificates, macOS may show an "unidentified developer" or "app is damaged" notice upon first opening.

When you run the installer for the first time, Windows Defender may display a blue "Windows protected your PC" alert.
Required System Permissions
PrepZero AI requires two standard OS permissions to function during technical rounds:
1. Microphone & Audio Loopback
Used to transcribe your voice and capture the interviewer's speech through the internal audio loopback. Audio is transcribed in real-time and never recorded to disk.
2. Screen Recording (OCR Only)
Allows the app to snip coding questions, LeetCode problem descriptions, and IDE code snippets when you press the OCR shortcut.
