Owners of Apple (NASDAQ:AAPL) mobile devices may want to think twice about what they say to Siri, the voice assistant in recent versions of iOS.
A spokesperson for Apple told Wired that the company stores Siri data for up to two years. Questions, orders and comments made to Siri are sent to Apple, which stores the data anonymously. The data is analyzed and used to help improve Siri’s responses.
Privacy advocates had raised questions about Apple’s Siri storage practices. The company has not previously disclosed what it does with user data or how long it is maintained.
According to the spokesperson, Siri data collected by Apple is linked to a random number associated with a particular customer, but not with his or her Apple ID or email. After six months, the data is separated from the random number.
Once a users deactivates Siri, any data associated with the user is deleted.
Privacy advocates have called on Apple to publicize its Siri Privacy policies for users to review.
Siri debuted with the launch of the iPhone 4S in 2011. When the company unveiled the iPhone 5 last year, Siri’s capabilities were not heavily highlighted.
Shares of Apple rose fractionally in midday Friday trading.
