The language spoken by participants during a phone call is also easily classified as “metadata” and could be defended as non-identifiable info with a straight face. So are the number of speakers on the call, the topics of conversation, the intensity of emotions displayed, voice stress levels, and the presence of certain keywords, if you squint a little. The lack of a literal call transcript does not matter much in terms of privacy.

I don’t know anything about this system, but the fact that screen shots are not ultimately stored on the user’s PC doesn’t mean anything if the content has already been classified and indexed. It will be fished.
