Discover a different way to own your digital life
Your Most Trusted Device is
Not on Your Side
You use your phone and computer for everything: Work. Money. Messages. Identity. But the device you rely on most is also the one you control the least.
Built as open platforms for data harvesting and surveillance, your daily OS sees every keystroke, your apps track every move, and your data lives where you don’t own it. In this ecosystem, you aren’t the owner. You are the product.
Existing solutions, like hardened or "secure" operating systems, force a false choice: privacy or usability. They replace your daily system, break ecosystems, and limit apps, pushing you to carry two phones or reflash the one you depend on just to feel safe.
Security and privacy shouldn’t require sacrifice.
Freedom begins when you step outside the system — not by hardening it, but by separating from it. To secure your digital world without compromising your daily habits, software solutions are no longer enough.
You need a physical boundary.
So We Built One
Meet PlugMate: a separate, trusted device for your private digital life
TrustKernel PlugMate is a thumb-sized computer that runs its own fully isolated Android system. It doesn’t run on your phone or PC; it runs through them.
Simply plug it into your phone or computer to instantly launch a secure, private workspace for your data, apps, and identity.
A New Way to Carry Your Private Computing Space

Mini Size, Fully Functional, Serious Performance.
PlugMate is a fully functional Android computer, not a stripped-down device. It runs standard Android apps, supports video, audio, camera, maps, messaging, browsing, wallets, and productivity tools - just like a phone or tablet.
How is it possible: PlugMate contains its own processor, memory, and fully encrypted storage, while securely reusing peripherals from the connected phone or computer without exposing your data. This design keeps PlugMate incredibly small, while computation and data remain fully isolated.

With an 8-core processor, 4GB memory, and 128GB encrypted storage packed into a device weighing just 14.3g, PlugMate delivers serious performance in a thumb-sized form and is powered directly by your phone or computer.
No battery, no decay, no recharging. Unlike secondary phones, PlugMate removes the battery, not capabilities. It draws minimal power from the host, ensuring it remains your "digital vault" for the next 10 years without needing a charge.

Isolation
Isolation
Your data lives only inside PlugMate. Encrypted.
With its own processor, memory and storage, PlugMate remains isolated from the host device. The only connection is a single Type-C interface, drastically reducing attack surfaces.
All data is encrypted by hardware at rest and is never exposed.

No Trust. No Boot.
Before PlugMate starts, two secure-chip verifications must succeed:
This innovative pre-authentication boot process blocks:
- Device authentication: PlugMate only boots when connected to an authorized device.
- User authentication: only an authorized user can unlock and boot PlugMate.

Privacy by Design
Your Data, Yours Only.
PlugMate is built with privacy by design. Access, usage, and control of your data remain exclusively in your hands.
Privacy is not achieved by removing capabilities, it's achieved by giving you control over them.

PlugMate isn't just for "privacy geeks", it's for anyone who needs a separate, trusted digital space.
Risk Isolation
Keep uncertain apps and activities away from your main device
Some apps are necessary but don't belong on your everyday phone — apps you don't fully trust or simply don't want mixed with your personal device. Installing them directly mixes unknown risk with your photos, contacts, and accounts.
PlugMate creates a hardware-level sandbox. By moving these apps to PlugMate, your main phone remains clean. Unplug the PlugMate, and the risk vanishes.

Data & Asset Protection
A hardened vault for high-stakes assets
Some moments carry higher stakes than everyday use. Credentials, sensitive data, and digital assets demand stronger guarantees than software protection alone.
PlugMate creates a physical security boundary. Your data and assets stay protected inside its own trusted system, independent of your phone or computer.

Cross-Platform Freedom
One Android system across all your devices
You may love iPhone or Mac hardware, but closed ecosystems limit flexibility. Carrying a second phone is an awkward compromise.
PlugMate bridges the gap. Plug it into any Type-C phone or computer and instantly access a full Android system. Get the freedom of a second phone without the bulk.

Personal Control & Privacy
A system that you fully own and control
Privacy is about control — when a system runs, where data lives, and who can access it. Always-on devices and managed environments take that control away.
PlugMate is your "ghost" system. The system, the apps, and their behavior exist only on your terms and under your control. Plug it in when you choose. Unplug it, and everything stops.
