Amazon is being sued over its smart assistant's recordings of children. Two US cases allege the firm lacks consent to create voiceprints that could let it keep track of a youngster's use of Alexa-enabled devices and thus build up a "vast level of detail about the child's life". Amazon has said it only stores data once a device-owner has given it permission to do so.
