Understand permissions requested by apps and extensions
Apps and extensions that you install may have access to your data. When they do, you'll see a warning. You may also see a warning when an app or extension gets updated and it wants new or different permissions.
A warning doesn't necessarily mean the app or extension is dangerous, just that it can be.
Note: If you suspect an app or extension to be unsafe, don't install it. You can check an item's ratings and reviews to help you decide if it's trustworthy.
Where you may see permissions
You may see a permission notification if you do the following:
- Install new items. Apps and extensions may need to use your personal data to work properly. You'll have to decide if you feel comfortable sharing your information.
- Update an item. You might see a warning message when an extension or app you already have gets updated. That's because the update might include new or different permissions.
Recognise permission levels
Below are the permissions apps and extensions may request and their potential risk levels. You can always uninstall an app or extension if you’re not comfortable with the permissions it requests.

Data that you copy and paste

This alert means that the item may ask you to deny or allow optional permissions after it's been installed. If you allow optional permissions for an item, you can't change them after that.
