It's three layers, and you can inspect every one of them.

We don't ask you to flash firmware or trust a black box. We start with hardware you already know and build up from there, in the open.

01

Google Pixel

Pixel hardware — the platform GrapheneOS is built to run on, with its dedicated hardware security module.

02

GrapheneOS

A hardened, de-Googled Android with file-based encryption bound to the Pixel's security chip, tighter per-app permissions, and no tracking baked in.

03

Vault Phantom layer

Our security app and concierge setup add wipe-on-trigger defenses and turn on the operating system's strongest protections for you.

The hardened base

Encryption you don't have to think about.

Before a single Vault Phantom feature loads, your phone is already among the most hardened in the world. This is the protection working underneath everything else on this page.

Locked, your data is just noise.

GrapheneOS uses file-based encryption with keys bound to the Pixel's secure element — the dedicated security chip that also guards the unlock screen. While the phone sits locked, your files, messages and photos stay encrypted at rest. There's no software-only shortcut around it, and every profile gets its own keys.

Keys sealed in hardware

Encryption keys live in the Pixel's secure element, not in plain software. A locked device gives up nothing, even to someone holding it.

Falls back to a locked state

Left idle for a window you set, the phone reboots and purges its encryption keys from memory — back to the "before first unlock" state that resists extraction tools.

Brute-force throttled in hardware

Wrong-guess limits are enforced by the secure element itself, not just the software — so the lock can't be rushed by a machine guessing PINs.

Permissions you actually control

Revoke Network or Sensors access per app. Hand over a scoped slice of your storage or contacts instead of all of it. Apps get what you allow, nothing more.

De-Googled, no telemetry

No analytics or tracking baked into the OS. Google Play, if you want it at all, runs sandboxed like any other app — with no special privileges.

Hardened to the metal

A hardened memory allocator, memory tagging on supported Pixels, verified boot, and the option to switch the USB port off at a hardware level.

Built on GrapheneOS — the hardened, open-source Android that privacy researchers and journalists actually trust. We deliver it fully configured and verified, with the Vault Phantom layer on top.

// The defenses

Seven ways the phone can lock down — or erase.

Seven independent defenses, configured and proven on every device before it ships — working the day you need them, not toggles someone hoped were left on.

01

Remote SMS Wipe

Phantom Core

A coded text from a trusted number — like ●●●●●●●● — erases the device instantly, wherever it is.

Set up with one trusted contact you choose.
02

Dead Man's Switch

Phantom Core

If the phone is left with no connection for a window you choose, it erases. A blunt last resort for the highest-risk moments.

Long fuse by default — no false alarms.
03

Emergency Button Wipe

Phantom Core

Five fast presses of the power button erases the device — no unlock, no menu, no app to find. The one defense you can trigger yourself, in the pocket, without looking.

Deliberate enough that it can't happen by accident.
04

Duress PIN

GrapheneOS

A second PIN that wipes the phone the moment it's entered — while looking exactly like a normal unlock.

Configured and verified on your device.
05

Auto-reboot

GrapheneOS

Left idle, the phone restarts itself back into a fully-encrypted, locked state — blocking extraction without destroying anything.

Set to a sensible window for you.
06

Inactivity Wipe

GrapheneOS

If the phone isn't unlocked for a long stretch you set, it erases. Resets on every unlock, so normal use never trips it.

Tuned so everyday use never trips it.
07

Brute-force Guard

GrapheneOS

After too many wrong unlock attempts in a row, the phone erases. Tuned to consecutive failures, not scattered typos.

Set up and proven on your device.

Vault Phantom on a Pixel 8a

The triggers we built Phantom Core

Remote SMS wipe, the dead man's switch and the five-press emergency wipe — our own defenses, armed and managed from this screen.

Every protection, armed

Duress PIN, auto-reboot, inactivity and brute-force wipes — every protection switched on, tuned, and verified for you.

Status you can trust

The screen shows exactly what's armed, in real time — no fake badges, no green ticks for protections that aren't actually on.

People whose data is a target.

Professionals with a duty to protect

  • Lawyers holding privileged client files
  • Doctors and clinicians with patient records

Concierge

The setup is the product.

Anyone can read a guide. What you're really buying is a device that arrives ready, configured by someone who does this all day — and stays reachable after.

01

Configured

Each phone is flashed, hardened, and set up by hand before it ships. Nothing left half-done.

02

Verified

We test the defenses on the device, so you're not trusting a toggle that was never proven.

03

Supported

We walk you through the GrapheneOS-native protections and stay reachable as your needs change.

Straight answers.

Are you affiliated with GrapheneOS? +

No. Vault Phantom is built on top of GrapheneOS, but we are independent and not affiliated with, endorsed by, or partnered with the GrapheneOS project. We point you to their native features and configure them for you.

Could a wipe erase my data by accident? +

The triggers are powerful, so we ship them with conservative defaults and long thresholds, and we set them up to match your actual needs. Nothing aggressive is turned on without you understanding it first.

Is this on the Play Store? +

No. This isn't an app you download — it's a complete device we configure and deliver. The security software is part of that setup.

Is this legal to own and use? +

Yes. Vault Phantom is for protecting your own lawful personal and professional data. Understand your local laws before relying on any wipe feature in a specific situation, such as at a border.
