Apple has no way to decrypt iMessage and FaceTime data when it’s in transit between devices. So unlike other companies’ messaging services, Apple doesn’t scan your communications, and we wouldn’t be able to comply with a wiretap order even if we wanted to.

    Great article! It’s an important subject that many more should be considering for their daily lives. It’s unfortunate that citizens even must consider such privacy measures to maintain a basic international human right. Have you heard of Wire app? (www.wire.com) We’re testing it for ourselves now. They appear to also be e2e. The performance is excellent for chat, but the voice & video is a bit buggy. I’m interested in your thoughts. Thanks.
