Canvas Privacy Protection

By: Amy N
Prevents Canvas LMS from tracking page visibility and warns about Google tracking analytics

Features & Capabilities

Tired of unfair academic integrity accusations based on faulty Canvas quiz logs? Many instructors misinterpret Canvas's official data, leading to honest students being falsely accused of cheating just for switching tabs or minimizing a window.

Canvas Privacy Protection is your shield against these misleading metrics. This extension overrides Canvas's page visibility detection by making your browser always appear focused and visible to the website. It blocks the specific event listeners that detect when you leave a website, minimize the page, or lose focus, ensuring the page always reports itself as "visible" and "focused." This means: No more false "tab-switching" logs: Your browser will always appear to be actively focused on Canvas, preventing misinterpretations of legitimate study habits, interference from browser tab offloading, notifications, bathroom breaks, and more.

Protection against flawed data: We ensure your Canvas experience aligns with Canvas's own documentation, which states that "Quiz logs should not be used to validate academic integrity or identify occurrences of cheating." What this extension does NOT do:

It does not interfere with other Canvas functionality or logging.

It does not provide any unfair academic advantage.

Instructors can still see essential data like your IP address, device identifiers, and how long you spend on each question.

Enhanced Privacy Beyond Canvas

We go a step further! This extension also provides crucial guidance to protect your privacy on Google Docs, Sheets, and Slides. Did you know document owners can see your view history on enterprise Google accounts? This feature has also been misused to falsely accuse students.

We'll guide you through simple, manual steps to disable these Google view history settings, helping you maintain your privacy. Our extension will even alert you with a warning banner if you view Google documents before you've disabled these settings, ensuring you're always protected.

Additionally, we allow users to set the extension to run on any page they want by making those sites also always appear focused. There are many use cases for wanting to make a website think you are focused such as preventing session timeouts, ensuring continuous live updates on dashboards or news feeds, avoiding automatic video or audio pauses when switching tabs, and maintaining optimal performance for complex web applications or browser-based games.

For maximal privacy, we always recommend saving all course materials locally! Canvas even has an export course feature to help you do this.

Is Canvas Privacy Protection Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Canvas Privacy Protection requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
