You probably know how much data Siri uses, but do you know how long Apple keeps your Siri data on its servers?
Wired reports that Apple spokeswoman Tracy Muller told them that Apple stores your Siri data for up to two years.
Wired explains how the process works:
Whenever you speak into Apple’s voice activated personal digital assistant, it ships it off to Apple’s data farm for analysis. Apple generates a random numbers to represent the user and it associates the voice files with that number. This number — not your Apple user ID or email address — represents you as far as Siri’s back-end voice analysis system is concerned.
Once the voice recording is six months old, Apple “disassociates” your user number from the clip, deleting the number from the voice file. But it keeps these disassociated files for up to 18 more months for testing and product improvement purposes.
“Apple may keep anonymized Siri data for up to two years,” Muller says “If a user turns Siri off, both identifiers are deleted immediately along with any associated data.”
Muller has clarified that the data is anonymized and the company only collects the Siri voice clips in order to improve Siri itself. She says “Our customers’ privacy is very important to us.”
It’s nice to know how long Apple keeps our Siri data on its servers, but I doubt anyone will be paranoid about it, especially when the data is anonymized.
