Secure today. Own tomorrow.
Built for privacy. Designed for freedom.
One device, built around a single principle: your communication is yours. Encrypted calls, separate work and private modes and its own secure app ecosystem — the IMPulse on the CryptoData platform.
Air-gapped security
Works without a SIM card via a Matrix ID. No connection you did not set up yourself — a smaller attack surface.
Crypto protection
A built-in Vault wallet to send and receive supported cryptocurrencies. Your keys, your control.
Privacy by design
No Google services, no external app store. The operating system blocks apps from outside.
Built to stay safe
Hardware-level security with a physical Private Key and Worm Guard against malicious software.
Security
Encryption to the core
The IMPulse uses the Voice over Blockchain Protocol (VoBP) and proven, public cryptographic standards. No marketing — just what it actually does.
Two modes, one device
Privacy mode & Unsecure mode
Secured
Communicate through your Matrix ID — encrypted calls, messages and video calls, even without a SIM card over wifi. For everything that must stay private.
Regular SIM
A normal SIM card for everyday calls. Note: regular calls and texts can — as with any phone — be intercepted.
Ecosystem
A secure app world of its own
No external app store, no tracking. Only apps that run inside the secure CryptoDATA operating system.

What users across Europe say
Reviews from different countries — automatically translated into your language.
Finally a device that lets me have sensitive conversations without worrying. The separate modes are exactly what I needed.
Client communication stays confidential. The encryption works seamlessly and the Private Key gives me extra peace of mind.
Takes a moment to get used to the closed ecosystem, but then you would not want anything else. Solid and well thought out.
Protecting my sources is my job. With the IMPulse I can communicate safely wherever I am.
The Vault and the encrypted calls are ideal for my work. Delivery to Spain went smoothly.
Technically neatly done. No Google services and no tracking — exactly what I was looking for.
We ordered devices for our entire management team. The rollout was easy and the support excellent.
My keys, my control. The built-in wallet and the hardware key make the difference.
Honest marketing and a product that does what it promises. No empty claims, just good security.
Patient data and conversations stay private. Easy to use once you have set it up.
Confidentiality is crucial for us. This device fits that perfectly.
Work and private life finally fully separated. I recommend it to my colleagues.

FAQ
Frequently asked questions
Is this the most secure phone in the world?
No. No device offers absolute security, and we deliberately do not make that claim. What the IMPulse does do: encrypt your communication, separate work and private life and keep you out of the regular app and tracking ecosystem. That significantly reduces your risk — it does not make you invulnerable.
Does it work without a SIM card?
Yes. In Privacy mode you communicate via a Matrix ID over wifi — encrypted calls and messages without a SIM card. For regular telephony you can also use a normal SIM card (Unsecure mode).
Can I install my usual apps?
No. The CryptoDATA operating system blocks external apps and has no regular app store. You use the secure app ecosystem (such as Calls, Group chat, Email, Vault). Fewer apps from outside means less risk.
What is the Private Key?
A physical key that belongs to your device. It unlocks the device and your data — and you can use it to log in on another compatible device. Keep it safe: whoever holds the key has access.
Do you ship across Europe?
Yes, we ship across Europe. Please note that, due to the VoBP encryption algorithm, rules on importing and using encryption products may differ per country. Check the laws and regulations in your country before ordering. In doubt? Get in touch.
Which colours is the IMPulse available in?
Red, Gold, Army and Carbon. You choose your colour when ordering; every box includes all accessories. Availability per colour may vary.
