Apple is storing queries to Siri for longer that you might think
All of your swear words and other strange questions and queries that you asked Siri are being kept a little longer than you might think.
Anything you say to Siri is uploaded into the Apple’s storage for analysis. After that, Apple assigns you a random number that will be linked to your sound files. This is not your Apple ID or e-mail – just a random number.
If you want to cut all the links with your sound files you can just turn off Siri or don’t use it for a period of 6 months. This will unlink that random number, however, your sound files still will be stored for 18 months, because Apple uses them to improve the quality and performance of Siri. Trudy assured that those files are needed solely for that purpose.
Nevertheless, Nicole Ozer – the lawyer of the American Civil Liberties Union, advised to be careful and think about what you’re going to tell Siri, because if somebody will decide to decode that personal number, it will be possible to get information about you, your family, work, etc.
