Two products you can use today.
Vardum Messenger Public beta
End-to-end encrypted, post-quantum messaging with no phone number or email. Calls, groups, vaults and private notes. Free during the beta: a public beta on iPhone, and a small-group beta on Android by request.
Vardum Phones Taking orders
A Google Pixel running GrapheneOS, set up with Vardum and your apps. Three packages from A$750, delivered in 7 to 14 days in Australia. No SIM cards or eSIMs sold. Vardum is not affiliated with or endorsed by GrapheneOS.
In testing
AI that runs on your own device.
Both are in internal testing and review by our team before a beta release. Neither is for sale, and neither has a price or release date yet.
Vardum AI for Android In testing
A small assistant that runs on the phone itself: phone guidance, everyday help and small tools, with no AI account and no cloud AI.
Vardum Desktop In testing
Local AI for your computer: chat, build and fix code, research and review projects, with the model running on your own machine, not a cloud AI.
One promise
Your data stays on your devices.
Kept on your device
Messages are encrypted on your phone before they leave it. Our AI runs on the device in front of you, not on our servers.
Honest about limits
Every security claim is listed with its limits in our claims register. The messenger's code is open source.
