Apple has joined the dubious company of Google and Amazon in secretly sharing with contractors audio recordings of its users, confirming the practice to The Guardian after a whistleblower brought it to the outlet. The person said that Siri queries are routinely sent to human listeners for closer analysis, something not disclosed in Apple’s privacy policy.

The recordings are reportedly not associated with an Apple ID, but can be several seconds long, include content of a personal nature and are paired with other revealing data, like location, app data and contact details.
