Which Apps Can See or Hear You Through Your Laptop? Here's How to Check and Block Access

Your laptop's camera and microphone can remain accessible to apps long after you have finished using them. A video conferencing app, browser or other application that you previously granted permission to may still have access when you are not actively using it. This makes it worth checking which apps can use these devices and removing permissions they no longer need.

Both Windows 11 and macOS let you review and manage camera and microphone access through their privacy settings. You can also check browser permissions to see which websites can use these devices. The basic system-level check takes about two minutes, and here's how I recommend doing it.

Windows 11: Camera and Microphone Permissions

Windows 11 lets you manage camera and microphone access for individual Microsoft Store apps. Traditional desktop applications, including many browsers and video conferencing apps, have separate controls.

To check camera access:

1. Open Settings and go to Privacy & security.

2. Select Camera under App permissions.

3. Review the Camera access and Let apps access your camera switches.

4. Scroll down to see which Microsoft Store apps have requested access. Turn off permission for apps that do not need it.

5. Find Let desktop apps access your camera. Turn it off if you want to block camera access for desktop applications altogether.

To check microphone access:

1. Return to Privacy & security.

2. Select Microphone under App permissions.

3. Review the app permissions and turn off access where it is not needed.

4. Find Let desktop apps access your microphone and turn it off to block access for desktop applications.

It is worth noting that Windows lets you manage permissions individually for Microsoft Store apps. Traditional desktop applications have separate, broader controls under Let desktop apps access your camera and Let desktop apps access your microphone. The desktop app list may not show every application that can access these devices. You cannot individually switch off permissions for every traditional desktop app through these settings.

Browser Permissions: Check Which Websites Can Use Your Camera and Microphone

Browser-based meetings add another layer of permissions. A website such as Google Meet needs permission from both the operating system and the browser before it can access your camera or microphone.

On Windows, browsers such as Chrome, Edge and Firefox are desktop applications. This means they also need permission through Windows' desktop app controls.

You can review website permissions separately:

• Google Chrome: Open Settings, select Privacy and security, then Site settings. Choose Camera or Microphone to review website permissions.

• Microsoft Edge: Open Settings, select Privacy, search, and services, then Site permissions and All sites. Select a website and change its Camera or Microphone permission to Block.

• Mozilla Firefox: Open Settings, select Privacy & Security, scroll to Permissions, and select Settings next to Camera or Microphone.

Blocking a website in your browser prevents that particular site from accessing your camera or microphone. For example, you can block Google Meet in Chrome without affecting other websites. If you want to restrict Chrome's access across all websites, you can also turn off its permission in Windows settings. Microsoft's guide to camera, microphone and privacy settings explains how Windows manages these permissions and what happens when you turn them off.

macOS: Camera and Microphone Permissions

macOS lets you review and change camera and microphone permissions for individual apps through System Settings.

To check camera access:

1. Open the Apple menu and select System Settings.

2. Go to Privacy & Security.

3. Select Camera.

4. Review the apps listed and switch off access for those you do not want using the camera.

To check microphone access:

1. Return to Privacy & Security.

2. Select Microphone.

3. Review the list and switch off access for apps that do not need it.

macOS asks for permission the first time an app tries to access the camera or microphone. Once you grant permission, it remains active until you change it in System Settings. The list shows apps that have requested access, so an app that has never requested permission may not appear. You can review these permissions under Privacy & Security in System Settings, as explained in Apple's guide to controlling access to your Mac's camera and microphone.

You can also manage website permissions separately. In Safari, open Safari Settings, select Websites, and review the Camera and Microphone sections. Chrome and Firefox have their own site permission settings. Remember that a website needs both browser-level and macOS-level permission to access your camera or microphone.

Physical Controls That Add Another Layer of Privacy

Many Windows laptops have a physical camera shutter or a keyboard shortcut, often involving the Fn key and a camera symbol. Check your laptop's keyboard or user manual to see whether it supports either option.

A physical shutter blocks the camera lens, even if an app has permission to access it. However, it does not disable the microphone, so you still need to manage microphone access through your operating system's privacy settings.

MacBooks do not have a physical camera shutter. You can manage app permissions through macOS settings. The green indicator light beside the camera also lets you know when the camera is active.

A physical camera cover can also block the lens on either type of laptop. Check your laptop manufacturer's guidance before using one, as some MacBook displays have very tight clearances when closed.

What These Privacy Settings Do and Do Not Control

Turning off camera or microphone access does not uninstall an app or stop it from running. It prevents the app from using the relevant hardware through the permission you have restricted. You can restore access whenever you need it.

The distinction between system and browser permissions is important. Blocking a website in your browser restricts that site, while blocking the browser through the operating system can prevent websites from accessing the hardware altogether. On Windows, desktop app controls apply more broadly than the individual Microsoft Store app switches.

These settings also do not replace physical privacy measures. A camera shutter or cover blocks the lens, but it does not mute the microphone. If you use an external webcam or headset, check that the correct device is selected and review the relevant app and system permissions.

This is also why it is worth reviewing your permissions occasionally. Users on Reddit's r/Windows11 and r/privacy discuss checking which apps still have camera and microphone access, including applications they no longer use. Meanwhile, discussions on r/thinkpad and r/macbook highlight physical camera covers as an additional privacy measure. These are simple checks and precautions that can help you keep better control over access to your laptop's camera and microphone.

My recommendation: I would begin by reviewing camera and microphone permissions on my laptop and removing access for apps that no longer need it. I'd then check my browser settings and block websites that do not require access. It's a simple privacy check worth repeating occasionally.
