All Siri Commands
Apple basically keeps track of everything you’ve ever said to Siri. Right in the license agreement that some of you read, Apple let everyone know that the company studies Siri data to understand users and improve how Siri performs.
Apple isn’t alone in this – other voice assistants like Alexa also store conversations you’ve had for later analysis. However, conversations are not linked to your personal information, so when they are analyzed no one really knows where the conversation came from. However, they still have your voice on file with all the things you’ve said, and if you find that disturbing, there is a way to delete your Siri history.
Unfortunately, unlike Alexa, you can’t set Siri to autodelete history after a certain time – but we’re hopeful for that feature in the future.
