GrapheneOS Phone: The Most Private Smartphone Australians Can Buy

GrapheneOS phone running on Google Pixel — Australia's most private smartphone

In September 2022, the personal data of 9.5 million Australians was exposed in the Optus breach — names, dates of birth, home addresses, passport numbers, driver’s licences, Medicare card numbers. The Office of the Australian Information Commissioner is still pursuing Optus through the Federal Court over it. Weeks later, Medibank followed with 9.7 million health records compromised. Those two incidents alone affected more than half the Australian population.

If those breaches taught us anything, it’s that the systems most Australians rely on to protect their data simply aren’t built with privacy as the priority.

Your phone is the most personal device you own. It knows where you sleep, who you call, what you search for, what you buy, and who you talk to. The operating system running on that phone determines who else gets access to all of that — and by default, on a standard Android device, the answer is Google.

A GrapheneOS phone changes that equation entirely. It is the most trusted private mobile operating system available today, and it’s what Freedom Technology and Services installs on every deGoogled phone we supply to Australians.
For Australians seeking a GrapheneOS Phone solution, the answer starts here.

What Is GrapheneOS Australia's Recommended Private OS?

GrapheneOS is a free, open-source mobile operating system built on Android’s foundations — but with Google’s data collection architecture stripped out and a substantially hardened security layer built in its place. Developed as a non-profit project, it has been in active development since 2014 and is focused entirely on privacy and security research.

It looks and feels like a modern smartphone. You make calls, send messages, use apps, browse the internet, and manage your digital life without compromise. The difference is what’s happening underneath — or more precisely, what isn’t.

There are no Google services running in the background. No location data is being harvested. No behavioural profiles are being built and sold to advertising networks. The permissions system is far more granular than standard Android, giving you genuine control over what each app can and cannot access. As we cover in our post on the hidden risks of app permissions, most Australians have no idea how much access the apps on their standard phones have been silently granted — often including microphone, camera, location, and contacts running continuously in the background.

Why GrapheneOS Phone Specifically — Not Just Any Alternative OS

There are several alternative mobile operating systems out there, and we compare them in detail in our post onoperating systems available for a deGoogled phone. A GrapheneOS phone is our primary recommendation for one technical reason that its competitors cannot match: it supports full bootloader relocking.

When installing a new operating system on a phone, the device’s bootloader — the low-level program responsible for starting the phone — must be unlocked during installation. Most alternative operating systems require leaving it in an unlocked state permanently. This creates a hardware-level security gap. A GrapheneOS phone is the only privacy-focused mobile OS that allows you to relock the bootloader after installation, restoring the phone’s full hardware-level security verification.

Every time the phone starts, it cryptographically verifies that the software running on it is exactly what it should be — untampered, unmodified, exactly as installed. This is verified boot, and it’s a fundamental security property that most alternative operating systems simply cannot offer.

This is not a minor technical point. It is the reason that Edward Snowden — arguably the most scrutinised privacy advocate on the planet — stated publicly in 2019 that he would use a GrapheneOS phone as his base operating system, and later confirmed in 2022 that he uses it every day.

What GrapheneOS Actually Does Differently

Standard Android ships with Google Play Services deeply embedded at the operating system level. This gives Google sweeping, privileged access to your device — location, contacts, app usage, sensor data, and more — running continuously whether you use Google apps or not.

A GrapheneOS phone removes this entirely. Its security architecture includes several layers that don’t exist on any standard Android device:

Sandboxed Google Play. GrapheneOS offers the option to install Google Play as a fully sandboxed app — meaning it runs in a container with the same restricted access as any other app, with no privileged access to the rest of your device. If you need certain apps that require Google services, they work. But Google no longer has the keys to everything.

Hardened memory allocation. GrapheneOS uses a custom memory allocator that provides substantial protection against heap memory corruption — one of the most common classes of vulnerabilities exploited in mobile attacks. This makes exploitation of unknown vulnerabilities significantly harder even before a patch exists.

Per-app network controls. Each app can be individually restricted from accessing the internet entirely — including at the local network level. This is not available on standard Android.

Hardware-level camera and microphone toggles. GrapheneOS adds hardware-level toggles for the camera, microphone, and sensors. When disabled, apps receive zeroed data — not just a software-level block that can potentially be bypassed.

PIN scrambling. The lock screen randomises the position of numbers on each use, defeating shoulder surfing and some camera-based PIN capture attacks.

Duress password. A separate PIN can be configured to instantly wipe the device if entered — useful in situations involving physical coercion or border crossings.

Automatic reboot. The device can be configured to automatically reboot after a set period of inactivity, ejecting encryption keys from memory and returning to a fully locked state.

Screenshot metadata stripping. Standard Android embeds OS version, device model, and timezone data into screenshot EXIF metadata. GrapheneOS removes this entirely by default.

Wi-Fi MAC randomisation. GrapheneOS randomises the MAC address per connection, preventing Wi-Fi networks from tracking your device across locations.

If you want to understand how deeply surveillance has become embedded in everyday mobile technology, our post on how to stop your phone listening to you covers the broader picture. GrapheneOS addresses many of those vulnerabilities at the operating system level — not through settings workarounds.

Which Phones Run GrapheneOS?

A GrapheneOS phone is exclusively Google Pixel hardware. Not Samsung. Not Apple. Not OnePlus. Google Pixel only — currently the 7, 8, 9, and 10 series.

This is a deliberate technical decision, not a limitation. Google Pixel devices are selected because they are the only consumer smartphones that meet GrapheneOS’s strict hardware security requirements — including the Titan M2 security chip, proper verified boot implementation, and an unlockable and relockable bootloader. Broad device support, the GrapheneOS project notes, would be counter to its privacy and security aims.

This hardware-software combination is why a GrapheneOS phone can deliver security properties that no other mobile OS can match on consumer hardware.

Freedom Technology and Services sources these devices directly, installs GrapheneOS, completes the full configuration, and ships them ready to use. You don’t need to understand the technical process. That’s what we’re here for.

What FreedomTech Installs on Every Phone

When you receive a deGoogled phone from Freedom Technology and Services, it isn’t just a phone with a new OS flashed onto it. It’s a fully configured privacy system, ready to use from day one. Here is exactly what we install and configure on every device:

Brave Browser — our recommended daily browser, pre-configured with shields set to Aggressive, fingerprinting protection on Strict, and cookies cleared on exit. Brave blocks trackers, ads, and fingerprinting attempts by default without requiring any technical setup from you.

Signal — end-to-end encrypted messaging and calls. Signal is the gold standard for private communication and is used by journalists, lawyers, and security professionals worldwide. Notably, Signal’s leadership has publicly stated they will not compromise their encryption for any government — including Australia’s. Every message and call is encrypted end-to-end, and Signal cannot read your communications even if compelled to try.

ProtonMail — encrypted email from Switzerland, where privacy laws are among the strongest in the world. Your emails are end-to-end encrypted, and Proton has no ability to read your messages. We configure a Proton account or alias as the default email client on every device.

Mullvad VPN — a no-logs VPN service based in Sweden that accepts anonymous payment and does not require an email address to sign up. Mullvad routes your internet traffic through an encrypted tunnel, masking your IP address from every app and website you use. We pre-install the Mullvad client so it’s ready to activate.

F-Droid — an open-source app store containing thousands of free, privacy-respecting Android applications. F-Droid is your primary source for apps on GrapheneOS and contains alternatives to almost every mainstream app you currently use.

Sandboxed Google Play (optional) — for clients who need access to apps not available through F-Droid, we can configure sandboxed Google Play in an isolated profile. This gives you access to the Google Play Store while keeping Google Play Services in a container with no privileged device access.

We also configure your device’s network permissions, review default app settings, and walk you through how everything works in a .pdf manual we email out to you.

As our client Terry noted: “Love having no bloatware and much better permissions control.” That clarity comes from the configuration we put in — not just the OS.

The Signal and Australia Situation — Worth Knowing

One thing worth understanding as an Australian using Signal: the Australian Government has been pushing for legislation requiring tech companies to provide backdoor access to encrypted communications under the Telecommunications and Other Legislation Amendment (Assistance and Access) Act.

Signal’s response has been unambiguous. As Signal Foundation president Meredith Whittaker stated publicly, Signal will withdraw from Australia entirely rather than compromise its encryption. The reason this matters is actually reassuring: Signal’s architecture means it genuinely cannot read your messages even if it wanted to. There is nothing to hand over. That technical reality is the whole point.

Running Signal on a GrapheneOS phone — where neither the OS nor the messaging app has any pathway to your data — is the most private mobile communication setup available to Australians today.

Who Is A GrapheneOS Phone For?

The honest answer is that a GrapheneOS phone is for anyone who takes their digital life seriously

Journalists and researchers protecting sources. Lawyers and healthcare professionals with confidential client obligations. Business owners who don’t want communications handed to competitors via data broker networks. Crypto investors who understand that a compromised phone is a direct pathway to compromised assets — something we explore further on our crypto computers page. Parents who want a phone that doesn’t build a behavioural profile of their child from the first app download. And everyday Australians who watched the Optus and Medibank breaches unfold and decided to stop leaving their data in the hands of companies that treat it as a commercial asset.

You don’t need to be technically literate. You don’t need to understand what a bootloader is. You need a phone that works properly and doesn’t treat your private life as a product.

GrapheneOS and the App Question

The most consistent concern we hear from Australians considering a deGoogled phone is apps. Will I lose access to what I rely on?

For the majority of people, the answer is no — or at least, not in any meaningful way. With sandboxed Google Play configured, most Android apps run normally. F-Droid provides open-source alternatives to virtually every category of app. We cover the full landscape of alternatives in our post on switching apps to a more private mobile experience.

The apps that occasionally present issues are those using aggressive integrity checks — some Australian banking apps can flag the modified OS. This varies by institution and is steadily improving as GrapheneOS adoption grows. The community-maintained banking app compatibility list at PrivSec.dev is a useful reference for checking your specific bank before making a decision.

Signal, ProtonMail, Brave, Mullvad VPN — everything we configure on your phone works flawlessly. For the way most privacy-conscious Australians actually use their devices, GrapheneOS is not a compromise. It is a material improvement.
