The overlay is invisible to screen capture, screen recordings, screen sharing, and window enumeration — operating at the macOS window server level below all proctoring software.

How does the overlay stay invisible?
LDBypass operates at the macOS window server level. The overlay window is configured with private system APIs that exclude it from CGWindowList enumeration, screen capture, and screen recording. Proctoring software running at the application level cannot detect it.Do I need a ChatGPT or Claude account?
Yes. Log into your AI provider in a regular browser first. LDBypass uses your existing session cookies — no separate AI login needed.What happens if my time runs out during an exam?
The app provides warnings before expiry and includes a 30-second grace period. You can purchase more time directly in the app without interrupting your session.Does it work on Intel Macs?
Yes. LDBypass is a universal binary with native support for both Apple Silicon (M1/M2/M3/M4) and Intel processors running macOS 12+.Can proctoring software detect LDBypass?
No. Proctoring software like LockDown Browser, Proctorio, and ProctorU operates at the application or browser level. LDBypass operates at the macOS system level, below what these applications can monitor. The overlay does not appear in any screen capture API, window list, or recording.How do I get support?
