Privacy Within Documents:
Privacy allows you to choose who can see which documents and if they can share them or not. When uploading a document it defaults to sensitive, the highest privacy setting, but you can change it at any time. To change the privacy setting click on the three dots to the right of the document you'd like to change and select "Change Privacy". You will then see a screen with the different privacy options as well as what applies to each. Select the option that best fits your needs and finally click "Save".
