Does Canvas Track?

Does Canvas track tab switching?

Short answer: yes, on quizzes. The moment your quiz tab loses focus, Canvas writes it to the log — timestamped, for your instructor to see. Here's how the signal works and the only reliable way around it.

YesThe short answer

Does Canvas track tab switching?

Yes — on Classic Quizzes. Canvas logs a “stopped viewing the quiz” event every time the quiz tab loses focus, with a timestamp, in the quiz log your instructor can open. The fix isn't to hide it — it's to never switch tabs in the first place.

How Canvas tracks it

Every browser exposes a Page Visibility API that fires an event the instant a tab is hidden or shown. Canvas listens for it during a Classic Quiz and writes a “Stopped viewing the Canvas quiz-taking page” entry, then a “Resumed” entry when you return. It's the same signal our tab-switch test uses — try it and watch the counter move.

What the instructor actually sees

Not a video — a timeline. The quiz log lists each stop and resume with timestamps, alongside when you answered and changed answers. One or two switches are background noise. A timed quiz with a dozen of them, each lining up with a correct answer, is the pattern that gets an attempt reviewed. You can see exactly how it reads in the quiz log simulator.

The only reliable workaround

You can't delete the event after it fires, so the answer is to never create it. That's the whole point of the CheatGPT extension: it reads the question and answers it inside the quiz page, so there is no second tab to switch to and nothing for the log to record.

Frequently asked questions

Does Canvas track tab switching?
On Classic Quizzes, yes. Every time the quiz tab loses focus, Canvas records a “stopped viewing the Canvas quiz-taking page” event, and a “resumed” event when you come back — both timestamped in the quiz log.
Can instructors see how many times I switched tabs?
Yes, if they open the quiz log for your attempt. It lists each stop/resume with timestamps. Most don't look unless something prompts them to — but the record is there.
Does Canvas know which tab I switched to?
No. It only knows the quiz page lost focus. Browsers keep tabs sandboxed from each other, so Canvas can't see the destination tab or its contents.
How do I stop Canvas from tracking my tab switches?
You can't suppress the event, so the only reliable approach is to not switch tabs. CheatGPT answers questions inside the quiz page, so there's no focus-loss event to record.
Does this happen on New Quizzes too?
Behavior varies by Canvas version and settings, but the tab-focus signal is a standard browser capability. Treat any timed quiz as if switching away is logged.
