A little more privacy, right in Chrome
Privacy,
kept simple.
Keep your tab switches private during Canvas quizzes and exams. Canvas Tab Shield helps prevent tab-switch entries from appearing in the activity logs your teachers can view.
Built for Canvas. Made for Chrome.

What changes in
the activity log.
Canvas quiz logs can record when you leave and return to a quiz tab. Tab Shield targets those tab-switch signals.

Simplified from example quiz sessions. Tab Shield does not erase existing log entries or hide answers and submissions. Results can depend on the Canvas page and browser.

A few useful answers
Before you open
another tab.
What does tab privacy do?
It helps you switch tabs without generating the “Stopped viewing the quiz-taking page” and “Resumed” entries that teachers can see in Canvas quiz activity logs. Your answers and submissions remain visible. It targets Canvas tab and focus signals; separate monitoring tools may behave differently.
When does a day pass expire?
Exactly 24 hours after successful payment, not at midnight. The extension shows the expiry date and time in your local time zone.
How do I restore my purchase?
Sign in with the same verified email on the website or in the extension. Your membership is linked to that account. Existing license-key purchases can be linked after signing in.
Can I change my monthly plan later?
Sign in to My account to manage billing or switch to lifetime. A lifetime switch is a separate one-time purchase; monthly renewal stops after payment is confirmed, with no prorated refund.
Does this replace my school's rules?
Use the extension in line with your institution's policies. It provides a browser privacy control and does not change your responsibilities when using Canvas.
