According to the analysis, here is what Zoom sends across to Facebook:
Facebook told Vice that it requires developers to be transparent about sending data to Facebook. Its privacy police states that if an app or a developer is using Facebook's SDKs, they further “represent and warrant that you have provided robust and sufficient notice to users regarding Customer Data collection, sharing and usage.”
Apart from this, the report also lays out other privacy issues with Zoom. Citing a report from Electronic Frontier Foundation (EFF), it said that hosts in Zoom calls can see if participants have the chat window open or not. Administrators can also see IP address, location data and device information of each participant.
