Android 15 has a built-in Private Space. How is PlugOS different?

And, will PlugOS support private space?

Android’s Private Space is a software feature that runs inside the same phone, on the same hardware, under the same firmware and trust root. It’s designed to separate profiles and data within a trusted device.

PlugOS is a portable private environment that runs on its own hardware — with its own CPU, memory, storage, and boot chain. The phone (or computer) it’s plugged into is treated as an untrusted interface for display, input, and connectivity.

Because of this, the two solve different problems:

  • Private Space assumes you trust the phone and want better isolation inside it.

  • PlugOS assumes you may not fully trust the phone, or want your private environment to move across devices.

They are not mutually exclusive. PlugOS can be used together with a secure or privacy-focused phone, and PlugOS itself will also support Private Space–style isolation inside PlugOS in future versions.

So the difference is not about features, but where the trust boundary is drawn.
