Apple keeps Siri data for up to two years

Apple has revealed that Siri data is stored on the company’s servers for up to two years. Apple spokeswoman Tracy Muller noted the data is anonymized, and the voice clips are only collected to improve Siri. Siri users are assigned randomly generated numbers when using the software, and are represented by these numbers, rather than Apple IDs or email addresses. After six months, Apple “disassociates” user numbers from voice files. Those files are then kept for up to 18 more months. [via Wired]
