Allow apps to use your Documents folder
Some apps and websites can use your Documents folder to provide you with services and features. For example, an app might use your Documents folder to access specific files in the folder. See Control access to files and folders.
To authorise an app or a website to use information from your Documents folder, click Allow in the dialogue. If you don’t want to authorise the use of your Documents folder, click Don’t Allow.
If you allow third-party apps or websites to use your Documents folder, any information they collect is governed by their terms and privacy policies. It’s recommended that you learn about the privacy practices of those parties.
You can review and change which apps and websites can use your Documents folder in Privacy & Security settings.
Choose Apple menu > System Settings, click Privacy & Security in the sidebar, then click Files and Folders on the right. (You may need to scroll down.)
