Safety and Privacy Concerns

False end-to-end encryption claims

Zoom claimed that it’s video-conferencing was end-to-end encrypted, meaning that only the people attending the meeting could see the video or chat messages. However, in reality Zoom management had the means to view the video calls and chats if they wanted to, meaning hackers could also find a way. While this deceptive practice has been corrected, it does not set a good track record, and end to end encryption is not enabled by default.


Zoom bombing

Zoom bombing occurs when an uninvited user joins a meeting and hijacks the meeting by taking over the screen share function and showing offensive or obscene materials. This can happen because the unique meeting ID can be leaked, randomly guessed, or in case of a public meeting, be accessed by anyone. While moderators can kick out these bad actors, it might be too late to stop them from posting bad content.


Sharing of information with Facebook

The Zoom app on Apple devices was caught sending user data to Facebook such as their location, device models, operating systems, and carriers. Although many other apps do this, Zoom did not state this practice in their privacy policy, as was subject to legal action. While this practice is no longer happening, it does not set a good track record.


Mozilla tips on how to control your data

The company mentions clear criteria to define retention periods, promises to not store data for longer than needed to offer services or as required by law. Hosts of Zoom calls can password-protect saved calls, password-protect meetings, lock a meeting to prevent new participants, turn on/off enter and exit chimes, mute participants on the call, and even remove participants from the call. All Zoom participants have the ability to annotate the video of a call, but only hosts can clear all annotations and disable annotation for everyone. In the paid version, Zoom hosts are able to record meetings, with the option of saving the recording locally to their hard drive or remotely to Zoom’s cloud.
