Alexa Keeps Voice Data
Amazon has admitted it doesn’t always delete the stored data it obtains through voice interactions with its Alexa and Echo devices.
The company told a US politician that it retains customers’ voice recordings and transcripts until the customer chooses to delete them.
Amazon says some are not removed, both because the company has to scrub the data from various parts of its global data storage systems and because Amazon chooses to hold on to the data without telling the user.
In other words, even if a user manually deletes the audio version, some text versions are still saved in separate storage systems.
