According to the EULA, video streams going through the video server are not kept or stored anywhere. The video server only performs simple stream broadcasting to connected colleagues. Video streams themselves passing through the video server are unblurred. That's how it works for now. Streaming blurred video to the server is a possible future improvement. This would require simultaneous streaming of two streams (with and without blur) when, for example, 2 colleagues out of 5 unblurred themselves for each other. The idea now is to see how attractive the concept is to people in general.
