All the requests people have made through Siri are being stored on Apple servers for a period of up to two years, says Apple spokeswoman Trudy Muller. The statement comes in response to Wired inquiries about ambiguity in Siri's privacy policies, initially pointed out by American Civil Liberties Union lawyer Nicole Ozer. Muller insists that Apple is anonymizing the request data, and only collecting voice clips in order to improve Siri.
