No account, no signup, no email, no password, no credit card. Just a phone.
GDPR. CCPA. LGPD. Governments worldwide are tightening privacy laws.
We developed a platform with zero knowledge about your personal information. Your device generates a key, that is your entire identity.
In early 2025, senior U.S. government officials used a commercial encrypted messaging app to discuss military operations. A civilian journalist was accidentally added to the group, because the app relied on phone numbers pulled from a user's contact list. One wrong tap, and sensitive information was exposed publicly.
The app encrypted the content. It could not prevent the wrong person from being added, and it could not prevent attribution once the messages were shared.
ZKA is architecturally different. Three layers prevent this.
Users connect through anonymous key exchange. There is no contact book to scroll through and no phone number to accidentally select. A civilian cannot be added to a group, because no mechanism exists to find or invite one.
Even when a group exists, the server does not know who is in it. There are no usernames, no phone numbers and no account records linking participants to real identities.
Captured or screenshotted messages show only anonymous IDs and initials. Nothing ties a message to a real person, so a leaked screenshot is unverifiable — the identity association does not exist at any layer.
Every product runs on the same patent-pending Zero-Knowledge Architecture. No accounts, no phone numbers, no personal data. Just a device keypair and end-to-end encryption.
Real-time encrypted GPS sharing within circles. See your people on a map without revealing your identity. Invite via code, approve members, share location privately.
VoIP calls encrypted within your circle. No phone number to dial, no carrier metadata, no call logs on any server. Just tap a circle member and talk privately.
End-to-end encrypted group messaging within circles. No phone number to sign up. No message history on servers. Just your initials and your words.
Share posts, photos, and updates within your circle. No public profile, no algorithmic feed, no data harvesting. Social networking built on privacy, not surveillance.
Connect wearables to share heart rate, SpO2, and glucose levels with your circle. Encrypted alerts when something is off. No medical records on any server.
Attach a ZKA tracker to your pet's collar. See them on the same encrypted map as your family. Geofence alerts when they leave a safe zone. All private.
Track keys, bags, luggage, and belongings on the encrypted map. No company sees what you are tracking or where it is. Private asset tracking within your circle only.
ZKA architecture separates data from identity at the infrastructure level. The server processes information without ever knowing who it belongs to.
Monitor patient vitals without storing personal information.
Track wellness and activity data without identity exposure.
Monitor residents without creating records tied to identity.
Track vehicles and assets without associating devices to employees.
Communicate without creating metadata tied to sender identity.
Share location intelligence without associating agents to coordinates.
Any workflow where data needs to flow without identity attached to it.
Your location. Your circle. Without sharing your personal information. ZKA Circle is the first app built on Zero-Knowledge Architecture, proving that real-time location sharing works without knowing who anyone is.
The same encryption protocol used by leading secure messengers. Every location update is encrypted on your device before it leaves. The server stores ciphertext it cannot read.
No name. No email. No phone number. Your device generates a cryptographic keypair. You choose 2-letter initials. That is all anyone sees.
Even with full access to our servers, all anyone finds is random IDs and encrypted blobs. We do not know who you are. We do not know where you are. By design.
ZKA Circle is the beginning. The ZKA Platform connects people, pets, belongings, and health data on one encrypted map. Here is what the future looks like.
Open the app. Enter your 2-letter initials. Tap "Enter Anonymously." Your circle is live in under 3 seconds.
Tap invite. A short code is generated. Send it via text or email. No URL, no browser, no tracking link, just a code.
They enter the code in the app. You approve. Encrypted location sharing begins instantly. Real-time. Private. Anonymous.
Monitor the people who matter most: elderly parents with heart conditions, diabetic family members, children with asthma. Their wearable tracks vitals. Your circle gets alerts when something is off. No medical records shared, no identity exposed, just encrypted alerts when it counts. This will be achieved through future partnerships with leading wearable companies.
Example Alert: Your mother's heart rate spiked to 142 bpm and she is not at a gym or exercise location. An encrypted alert was sent to 3 family members. The platform never saw the data, never knew who she is, and has no medical records on file.
AI that runs on your phone, not our servers. It learns patterns, detects anomalies, and alerts your circle, without any data ever leaving your device unencrypted.
"JJ has not moved in 2 hours." "AL is moving at highway speed in a school zone." Contextual alerts that understand patterns.
"Based on current movement, MK will arrive home in approximately 12 minutes." Local inference from encrypted data. No cloud processing.
Biomarker spike combined with unusual location triggers an automatic encrypted alert. AI connects the dots on-device only.
Group messaging within your circle. End-to-end encrypted. No phone number to sign up. No message history on our servers. Just your initials and your words.
Circle admins generate a view-only code. Enter it in any browser to watch the circle in real-time without joining it. Perfect for parents monitoring from a laptop, without being visible to the group.
Your identity is a cryptographic key on your device. When you first create it, the app generates a 12-word recovery phrase. Write it down. If you lose your phone, enter those 12 words on your new device and you are back in all your circles instantly.
We never see this phrase. It never leaves your device. It reconstructs your keypair on any new phone, the same way crypto wallets work. No cloud backup. You control it.
GDPR in Europe. CCPA in California. India's DPDP Act. Brazil's LGPD. Privacy regulations are tightening worldwide, and every major platform is scrambling to retrofit privacy into architectures that were built to harvest data.
ZKA does not retrofit. There is no data to breach, no profiles to leak, nothing readable to expose. As regulations tighten, platforms built on Zero-Knowledge Architecture will not need to adapt. They are already compliant by design.
Everything above this line works today. Everything below it is direction, not product. The same zero-knowledge architecture extends outward — into the SIM, into the device, and into the AI layer that will replace the app.
Three phases, each adding a layer on top of the same architecture: first a custom SIM, then a hardened device, then a larger device on the same platform.
The next phase is ZKA developing its own Secure SIM — not a commodity data card, but a security component built directly into the zero-knowledge architecture.
A ZKA Secure SIM uses a custom APN (Access Point Name) that forces all device traffic through ZKA's private network, so the phone can only communicate through our encrypted infrastructure. No data can leak to the open internet, and any SIM can be remotely deactivated or geo-fenced from a central dashboard.
A regular SIM gives the phone access to the entire internet. A ZKA Secure SIM acts as a locked tunnel — the device can only reach ZKA servers. If it is compromised, it is killed remotely. If it leaves the operational zone, it shuts down automatically. The SIM becomes a security component, not just a data card.
| Capability | What it does |
|---|---|
| Custom APN | Forces all traffic through ZKA's private network. The phone can only reach ZKA servers, not the open internet — no data leaks, no unauthorized connections. |
| Fleet Management | A centralized dashboard for SIM control: activate, deactivate and monitor every SIM in the field. |
| Remote Kill Switch | Instantly disable a compromised SIM. |
| Geo-Fencing | Automatically disable a SIM the moment it leaves a defined operational zone. |
Where this is headed: the ZKA Secure SIM is not a commodity data card. It is a security component integrated into the zero-knowledge architecture.
The complete product vision is a purpose-built, locked-down device that runs only the ZKA platform. Every layer of the communication stack is controlled and secured — hardware, operating system, application and SIM.
| Hardened layer | Detail |
|---|---|
| Locked-Down OS | No pre-installed apps, no app store, no web browser, no bloatware — only the ZKA platform. |
| Hardware Kill Switches | Physical switches for camera, microphone and GPS. |
| Secure Enclave | Tamper-resistant secure enclave for encryption key storage. |
| Custom Secure Boot | A custom secure boot process — only authorized software can run. |
Where this is headed: the operator receives one device. Insert the SIM and they are operational in seconds. Every layer — SIM, device, operating system and encrypted platform — sits under the same security architecture.
The ZKA Book is a Chromebook-sized, locked-down device running the full ZKA app. It is not a separate product — it is the same app on a larger screen.
Everything the phone does — encrypted chat, voice, location, health, circles and posts — on the same encryption, the same zero-knowledge architecture and the same ZKA Secure SIM.
Purpose-built for the work that needs one: research, documents, mission planning and command coordination.
Secure browsing: web traffic routes through a ZKA private proxy — a site sees the proxy, never the user's device, location or identity.
ZKA hides what you communicate. How the device reaches the network decides whether anyone can tell a communication is happening at all. Bought in bulk, the identity chain breaks before encryption is even involved.
A unit purchases SIM cards in bulk under a single account.
SIMs are handed out internally. No external record shows which SIM went to which operator.
The carrier sees one bulk account, never an individual operator.
Not the carrier, not the server, not the platform operator. No point connects a person to their communication.
| Connection method | Carrier knows user? | Purchase tied to individual? | ZKA content hidden? |
|---|---|---|---|
| Personal carrier account | Yes | Yes | Yes |
| Bulk unit procurement | No | No | Yes |
| Wi-Fi only, no SIM | No | No | Yes |
ZKA's encryption is identical no matter how the device gets online — the platform is network-agnostic. The connection method only changes how much anonymity exists at the physical network layer, beneath the encryption.
The next generation of devices will act as edge nodes for AI, where a local model talks directly to a more powerful model in the cloud. That conversation travels through ZKA's existing encrypted channel.
A model on the device handles local queries and private processing.
The same encryption used for chat, voice and location. Anonymous ID. No user identity.
A model on ZKA infrastructure, not a third-party provider, for complex analysis.
The question itself is the sensitive data. Asking an AI to analyze a defense system reveals what you are working on; asking about a drug interaction reveals a medical condition. ZKA's architecture ensures the platform cannot see who is asking or what is being asked — the AI processes the query without knowing the human behind it.
