Zoom takes its users’ privacy extremely seriously.
We would like to share a change that we have made regarding the use of Facebook’s SDK.
We originally implemented the “Login with Facebook” feature using the Facebook SDK for iOS (Software Development Kit) in order to provide our users with another convenient way to access our platform. However, we were made aware on Wednesday, March 25, 2020, that the Facebook SDK was collecting device information unnecessary for us to provide our services. The information collected by the Facebook SDK did not include information and activities related to meetings such as attendees, names, notes, etc., but rather included information about devices such as the mobile OS type and version, the device time zone, device OS, device model and carrier, screen size, processor cores, and disk space.
