GoKawiilMuse headband maker InteraXon used brain data to train AI without telling users
A Science journal investigation found that InteraXon, maker of the $475 Muse EEG headband, used anonymized user brainwave data to train its AI brain model without disclosing this to customers until after being contacted by reporters. The investigation also reviewed dozens of other consumer EEG companies and found about a third had privacy policies that failed to clearly explain how brainwave data is handled, with four having no privacy policy at all.
