Apparently this prohibition only applies to "situations related to the workplace and education", and, in this context, "That prohibition should not cover AI systems placed on the market strictly for medical or safety reasons"

So it seems to be possible to use this in a personal context.

> Therefore, the placing on the market, the putting into service, or the use of AI systems intended to be used to detect the emotional state of individuals in situations related to the workplace and education should be prohibited. That prohibition should not cover AI systems placed on the market strictly for medical or safety reasons, such as systems intended for therapeutical use.
