Canvas Privacy Myths: IP Address, Wi-Fi, Devices, and What Canvas Really Sees

Short answer. Canvas sees what your browser tells it about the Canvas page itself. It does not see your Wi-Fi network, your other devices, what is on your phone, or what other browsers you use. It does see your IP address and your login activity, but that is normal for any website. Below is the myth busting list, plus the things that actually do log a lot more than Canvas does (hint: not Canvas).

Myth: Canvas can see other devices on my Wi-Fi

Reality: No. Your Wi-Fi network is your network. Canvas only sees the traffic that hits its servers. It has no awareness of other devices in your house, your roommates' phones, or the smart fridge in your kitchen.

Even your IP address only tells Canvas the public IP your router uses. It does not tell Canvas anything about what is happening inside your network.

Myth: Canvas can see if my phone is on the same Wi-Fi as my laptop

Reality: No. Canvas does not know what other devices share your IP. If you and a roommate are on the same Wi-Fi and both take a quiz on different laptops, Canvas can see two attempts from the same IP, but it cannot prove that you and your roommate are the same person or are sitting next to each other.

This is one of the most common Reddit fears and it is not how networks work.

Myth: Canvas can see what is on my phone

Reality: Hard no. Canvas runs on the device you accessed it from. If you took the quiz on your laptop, Canvas has no idea what your phone was doing. Not what apps were open. Not what you were texting. Not whether your phone was even in the room.

Myth: Canvas can see my browser history

Reality: No. Browser history is stored locally on your machine. Websites cannot read it. The only thing Canvas might know is whether you visited Canvas pages before in this session (because Canvas saves that). It does not know which other sites you visited today.

Myth: Canvas can see what I have copied to my clipboard

Reality: No. Clipboard is local to your operating system. Websites can read the clipboard only if you explicitly grant permission, and Canvas does not request that permission.

Myth: Canvas can detect if I am using a VPN

Reality: Sort of. Canvas sees an IP address. If that IP belongs to a known VPN provider, technically Canvas could check it against a list. Most schools do not do this for normal quizzes. Some lockdown browsers do.

Your professor reading the quiz log will not see "this student used a VPN." They might see "this attempt came from a different country than usual" if the IP geolocation is way off.

Myth: Canvas can see my Mac address or hardware

Reality: Hard no. MAC addresses do not leave your local network. Hardware identifiers are not exposed to web pages. The most a website can do is browser fingerprinting (a combination of screen size, fonts, timezone, etc.) which Canvas does not appear to use for quiz monitoring.

What Canvas can actually see

Now the realistic list:

• Your account. Once you log in, Canvas knows who you are.
• Your IP address. Standard for any website. Used to display sessions and detect obvious problems like simultaneous logins from two countries.
• Your browser and OS. Through the User Agent string. Canvas knows you are on "Chrome 130 on macOS" or similar.
• Your screen size. Through standard browser variables. Used for responsive layout.
• Your timezone. Set by your browser.
• What pages you visit in Canvas. Tracked for Analytics.
• What you submit. Quiz attempts, assignments, discussion posts.
• Quiz log events. Page focus changes within an attempt.

That is the actual visibility window. Less invasive than students fear, more than students would prefer.

What proctoring tools see (the real surveillance)

If your exam uses Respondus LockDown Browser, Honorlock, Proctorio, or any other proctoring tool, the rules change completely. Proctoring tools can see:

• Your entire screen.
• Your webcam feed.
• Your microphone audio.
• All running processes on your computer.
• All open browser tabs.
• All browser extensions.
• Your clipboard activity.
• Whether you are running a virtual machine.
• Network traffic to and from your machine.
• Eye movements (some tools).
• Face position (some tools).

These tools are not Canvas. They run alongside Canvas during an exam and have OS level access. They are also the actual reason most "Canvas is spying on me" rumors exist. The thing doing the spying is the proctoring software, not Canvas itself.

You can usually tell which one your exam uses:

• If you have to download a separate program: proctoring tool.
• If you have to allow a browser extension at exam time: proctoring tool.
• If your camera light comes on: proctoring tool.
• If the exam interface looks like normal Canvas and you only see "Take Quiz": just Canvas.

What about Canvas mobile apps

The Canvas iOS and Android apps log similar events to the web version but with slight differences in granularity. App permissions matter:

• They can see your account.
• They can read whatever is in the app itself.
• They cannot see your other apps unless you grant unusual permissions.
• They do not record video or audio unless the proctoring extension is doing it.

The mobile apps are not more invasive than the web version. They are not less invasive either.

How to keep your activity private during a Canvas quiz

The realistic list of habits, given what Canvas actually can and cannot see:

• Use a private browser profile if you share a machine.
• Turn off notifications during the quiz.
• Close other tabs and apps before starting.
• Plug in your laptop to avoid sleep.
• Use a single monitor.
• Do not switch windows during the quiz.

You do not need to hide your IP. You do not need to use incognito. You do not need to use a VPN. Those do not change what Canvas can see.

FAQ

Can Canvas see my location? Canvas knows the approximate location of your IP address. That is country level and sometimes city level accuracy. It does not know your GPS location.

Can Canvas tell if two students used the same computer? If both students log in from the same IP within the same window, Canvas can see two accounts from one IP. Without other evidence, that is not proof of anything (lots of students live together, share libraries, etc.).

Can Canvas detect if I am using two monitors? No. The browser does not report monitor count to websites.

Can Canvas detect if I am using a screen reader or accessibility tool? Canvas detects when certain accessibility APIs are in use because it provides accessibility features. It does not flag this as suspicious.

Will my professor see if I have other Canvas courses open in another tab? No. Each Canvas course is logged separately. Your professor sees activity in their course, not your other ones.
