The Vardum Privacy StackFor professionals
Your phone. Your messages. Your AI. Nobody else's.
For business owners, lawyers, journalists and anyone whose work runs on sensitive information. One box, set up for you: a Pixel 11 hardened with GrapheneOS, an encrypted messenger, an AI on the phone, and a private AI for your computer on a USB stick.
A$2,500
incl. GST · Pixel 11, 256 GB · Unlocked, SIM or eSIMShips the next business day after your invoice is paid
Now until 31 December: both AIs, Standard and Unfiltered, on your stick, plus your apps set up free.
- No phone number, no email. Your messenger identity isn't tied to you.
- No cloud AI. Both AIs run on your own devices.
- No Google account needed. GrapheneOS, set up for you.
- We hold no keys. We can't read your messages.
Who it's for
Built for people who can't afford a leak.
If your phone holds other people's secrets, an ordinary phone, a phone-number messenger and a cloud AI are three places they can escape from. The Stack closes all three.
Business owners and executives
Deals, pricing, staff matters and board talk. Message without a phone number attached, and draft with an AI that never sends your figures to a cloud.
Lawyers
Client confidences stay with you. Summarise, draft and research a matter on your own computer, and talk to clients over end-to-end encryption.
Journalists
Protect your sources. A messenger with no phone number or email to trace, a phone that limits what each app can reach, and research that never leaves your device.
Anyone holding sensitive data
Health, finance, HR, IT and security teams. If you hold or send records that aren't yours to lose, the Stack keeps them on devices you control.
The phone · GrapheneOS
An operating system built for one thing: your security and privacy.
iOS and ordinary Android are built to sell you services, with security added on top. GrapheneOS was built the other way round: every part of it was designed for security and privacy first. We load it onto a brand new Pixel 11, lock it down and set it up before it ships, so you get that protection without handing your life to Apple or Google.
GrapheneOS vs iPhone vs ordinary Android
| iPhone (iOS) | Ordinary Android | Vardum Phone (GrapheneOS) | |
|---|---|---|---|
| Account to use the phone | Apple ID for the App Store | Google account for Play | None needed |
| Data sent to the phone's maker | Some, to Apple | A lot, to Google, built in | No Google services unless you add them |
| Cut an app off the internet | Mobile data only | Not built in | Yes, Wi-Fi and mobile |
| Block an app's sensors | No | No | Yes |
| Show an app only the files and contacts you pick | Photos and contacts | Photos only | Any files, any contacts |
| Duress PIN that wipes the phone | No | No | Yes, if you switch it on |
| Restart to re-lock your data | After 3 days locked | After 3 days locked | After 18 hours, or sooner if you choose |
| Block USB data while locked | After an hour locked | Depends on the phone | Straight away, or charging only |
| VPN with lockdown, set up for you | You set it up | You set it up | Done before it ships |
| Extra protection against spyware | Strong, plus optional Lockdown Mode | Standard | Hardened memory and memory tagging, on by default |
Default features on current versions as of October 2026. Ordinary Android means a Pixel or similar phone with Google's standard software.
Hardened against attacks
A hardened memory allocator and extra exploit protections, including hardware memory tagging on Pixel, make spyware much harder to get in.
Network and sensor switches
Turn off internet access or sensors for any app. An app that can't reach the internet can't send your data anywhere.
Storage and Contact Scopes
Give an app only the files or contacts you pick, not your whole phone. The app doesn't know it's been limited.
Duress PIN and auto-reboot
An optional second PIN that wipes the phone, and a restart after a set time locked that puts your data back behind full encryption.
USB-C port control
New USB data connections are blocked while the phone is locked, so a cable can't be used to pull data. You can set it to charging only.
VPN lockdown and a new Wi-Fi identity
Bring your own VPN (we suggest Proton VPN) and we set it as always-on with "block connections without VPN". A fresh random Wi-Fi address for every connection.
Verified boot, relocked
The bootloader is locked again after install, so the phone checks the system hasn't been tampered with every time it starts.
Separate profiles
Keep work and personal apps in separate profiles, each with its own encryption, and end a profile's session to lock it away.
Unlocked, any network
Bought outright and unlocked, so it works on any Australian network: Telstra, Optus, Vodafone or their resellers. Use a regular SIM or an eSIM.

Vardum Unfiltered · 18+
Ask what ChatGPT and Claude won't answer. Nobody ever sees the question.
The big AI apps send every question to their servers, then decide whether you're allowed an answer. Unfiltered runs on your own computer. It answers frankly, and your questions never leave your device. Ask about a client's case, a leaked document or a deal under wraps, and it never touches a cloud.
How often each AI answers sensitive questions
| Cloud AI apps | Vardum Unfiltered | |
|---|---|---|
| Where your question goes | To the company's servers | Nowhere. It stays on your computer |
| Who can see it | The provider, under its own policies | Only you |
| Account needed | Usually, linked to your email | None |
| Works offline | No | Yes |
Vardum Unfiltered and ChatGPT: Vardum's own testing, 2026. Claude: 2024 model version on OR-Bench-Hard-1K, a published set of harmless questions that sound risky, built to measure over-refusal (Cui et al., 2024). Adults only: age check at checkout and an 18+ signature on delivery.
What's inside
Four pieces that work together, and none of them reports back to us.
Vardum Phone
A brand new Google Pixel 11 (256 GB) running GrapheneOS, hardened and set up with your VPN before it ships. Unlocked for any network, with a regular SIM or an eSIM. More about the phone

Two AIs, one stick
Standard for everyday work. Unfiltered for frank answers.
Standard
- Powered by Google's Gemma 4 (Apache 2.0)
- Works fully offline, even with the internet switched off
- Drafts, summarises and answers from your own documents, without uploading them
- Runs on 16 GB laptops without a graphics card
Unfiltered 18+
- Answered 95% of sensitive questions in our own testing
- Powered by Qwen 3.5, with refusals removed

Both are small AIs running on your own devices, so answers can be wrong. Check anything important. You're responsible for how you use them, and our terms don't allow using them for anything illegal.

Questions
The honest answers
Does this make me compliant with my professional duties?
No product can do that on its own. What the Stack does is cut down where your information goes: no cloud AI, no phone-number messenger, no Google account. Check your firm's or employer's policies, and your professional body's guidance, on how you store and send client information.
Can I still use my work and banking apps?
Most apps work on GrapheneOS, including through optional sandboxed Google Play. A few banking and payment apps refuse to run on anything but Google's own Android, so check your must-have apps with us before you order.
Is it safe to plug in a USB stick you send me?
Good instinct to ask. Every stick comes with a list of checksums for every file (SHA256SUMS.txt), so you can check nothing was changed before you use it.
Will the desktop AI run on my computer?
It needs Windows 10 or 11 and ideally 16 GB of memory. No graphics card needed: it runs on the processor, so answers take seconds to a couple of minutes, not instantly. Windows only for now.
What does "Unfiltered" actually mean?
It won't refuse ordinary adult questions or lecture you. It's for adults only, and we check age before we send it. You're responsible for how you use it, and our terms don't allow using it for anything illegal.
Do you see what I ask the AI?
No. Both AIs run on your devices. Your questions never reach us or a cloud AI.
