Whatever side of the Apple vs. FBI encryption debate you're on, there's no changing the fact that similar to the "guilty until proven innocent" principle, iPhones are encrypted until the courts decide otherwise.

It turns out that's not the case with Amazon's Fire OS. Locally stored data on Amazon Fire devices is no longer encrypted, The Verge reports.

The option to encrypt data goes away with the latest Fire software update. Twitter user David Scovetta tweeted a notification he received on his Fire HD, which said "encryption support will soon be deprecated on Fire HD (4th Generation) and Fire HDX 8.9 (4th Generation)." Fire TV devices also run Fire OS.

The alert said users "can stay on the Fire OS version until you are ready to upgrade," though that means you won't get patches for security vulnerabilities and new feature rollouts.

Amazon did not immediately respond to a request for comment, but a spokesperson told The Verge that some enterprise features were removed because customers weren't using them. The decision to remove encryption was made last fall.

To be sure, the option to encrypt local data isn't one most users give much thought to. There are no explicit encryption settings on the iPhone, for example; if you set a passcode, everything is encrypted by default. But the fact that Amazon removed it is sure to disappoint users who are suddenly aware of encryption's benefits thanks to the Apple-FBI spat.

It's also a stark contrast with the Android operating system on which Fire OS is based; Google mandates encryption for all Android phones shipped with Marshmallow or later.
