Short answer: free tools can help you understand and test Canvas quiz logs, but a real bypass needs browser-level event blocking during the quiz.
| Free tool | What it does | Link |
|---|---|---|
| Canvas Tracking Test | Shows focus/blur/visibility events live | Open |
| Quiz Log Explainer | Decodes log entries into plain English | Open |
| Professor View Simulator | Shows what actions look like from the teacher side | Open |
To actually block tab-switch quiz-log entries during Canvas quizzes, install Canvas Ninja and enable Privacy Guard.
