A secure phone is not a stock Android
with a privacy wallpaper.

A secure phone replaces the stock operating system with a hardened platform and preserves a verifiable boot chain. Privacy Devices builds and configures each phone before dispatch: GrapheneOS installed and relocked, Mullvad VPN, a 12-month global eSIM, a paid Threema identity, and the owner-controlled Phantom Protocol™ layer — armed and tested, not left for you to set up. Configuration and testing take 1–2 business days before tracked dispatch. Every device includes a 12-month warranty and a 14-day money-back guarantee — browse current models and live pricing.

What actually makes a phone secure

Most phones sold as "secure" are stock Android with a tweaked launcher. Ours is built differently: verified boot relocked, a hardened operating system, paid encrypted-comms licences, and an owner-controlled duress layer — every device configured and tested before it leaves our Australian workshop. Three layers underneath:

What you get in the box

One fully configured device. A 12-month Mullvad VPN license. A 12-month global eSIM good in 170+ countries. A paid Threema identity. Phantom Protocol armed with your chosen duress behaviour. Local AU SIM support configured. A 14-day money-back guarantee and 12-month hardware warranty.

What "secure" actually requires — at every layer

Most "secure" phones sold in Australia rely on a single layer: an encrypted messaging app, or a VPN, or a tweaked launcher. Single-layer security is not real security. A device that is genuinely hard to monitor, intercept, or compromise needs four layers stacked together.

Hardware

The Google Pixel 8 onwards ships with the Titan M2 security chip — a dedicated secure element that handles cryptographic operations, biometric matching, and key storage in a separate die from the main processor. Pixel hardware is also the only widely-available Android device whose secure boot can be relocked against a third-party operating system. Without that hardware foundation, no operating system layer can guarantee integrity. We exclusively ship Pixel.

Operating system

GrapheneOS replaces stock Android entirely. Google services are not present. The kernel runs hardened malloc, hardened C runtime, restricted syscall surface, and on Pixel 8 and later — Memory Tagging Extensions (MTE) at the hardware level. Publicly-known mobile zero-days targeting stock Android routinely fail against GrapheneOS because the exploit primitives they rely on no longer exist. The OS also enables per-app network and sensor toggles, multiple isolated user profiles, and a sandboxed Google Play option for the few apps you can't replace.

Network

Cellular networks know which tower your device connects to. That is unavoidable at the radio layer. What is avoidable is everything above the radio layer: DNS leaks, IP-based tracking, ISP-level deep packet inspection, and the ad/analytics SDKs in the apps you use. Every device we ship has Mullvad VPN configured with WireGuard, kill-switch enabled, and the connection forced through it. The included global eSIM provides a separation between your existing carrier identity and the device's network identity — useful for travel, source meetings, and any scenario where number-to-device correlation is a risk.

Operator (you)

The user is the weakest layer in any threat model. A hardened device used carelessly is no harder to compromise than a stock device used carefully. We pair every phone purchase with a written threat-model briefing and an optional 30-minute setup call, so you understand which behaviours your device protects against and which behaviours it does not. Our guide library covers profile separation, app discipline, network habits, border-crossing protocols, and duress drills.

How a secure phone differs from a "regular" phone

Real-world scenarios this phone handles

You are a journalist meeting a source. Your stock phone leaks your location to Apple/Google in the background, your apps phone-home over carrier network, and the metadata of who you texted is recoverable from your phone bill. Our device runs every connection through Mullvad, the messaging app stores nothing recoverable, and Phantom Protocol's duress PIN gives you a clean wipe path if questioned.

You are an executive crossing the AU border. Australian Border Force can compel device unlock under the Migration Act 1958 sec.252. The auto-reboot setting on our devices ensures that after a configurable idle period the phone returns to a "before-first-unlock" state — at which point even the device manufacturer cannot extract content. Decoy profiles let you hand over an unlock PIN that opens a clean profile, not your real one.

You are a domestic-violence survivor. Your stock phone is likely paired with cloud accounts the perpetrator may know. Our setup process erases that linkage entirely — new identity, new eSIM, new device with no recovery path. See the DV-safe phone page for the full protocol.

You are an activist or organiser. Targeted phone-tracking and IMSI-catcher surveillance is a real concern. The combination of Mullvad VPN + a private global eSIM + GrapheneOS profile separation makes you substantially harder to monitor than your peers using stock devices.

How we configure your device before dispatch

Every device goes through the same configuration pipeline before it leaves us:

• Bootloader unlocked, GrapheneOS flashed against current monthly release, bootloader relocked against GrapheneOS keys.
• Verified boot tested, attestation verified.
• Owner profile minimised: VPN, system settings, and the bare-minimum utilities only.
• Work profile created and pre-loaded with sandboxed Google Play, Threema, banking apps if requested.
• Mullvad VPN paid for, configured, kill-switch on, always-on enabled.
• Threema identity provisioned with a paid licence.
• Global eSIM provisioned and tested on AU networks.
• Phantom Protocol armed with your chosen duress PIN, auto-reboot interval, and remote-wipe trigger.
• Final integrity check, packed in tamper-evident packaging, dispatched.

This is a 2–4 hour process per device done by us. Self-installing on a phone you bought from JB Hi-Fi can theoretically replicate it — most self-installs miss two or three of the steps above and ship a phone that calls home in subtle ways the user never sees.
