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.
Every product runs on the same patented 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 Signal. 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.
If subpoenaed, all we can produce 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, no records to subpoena. As regulations tighten, platforms built on Zero-Knowledge Architecture will not need to adapt. They are already compliant by design.
Subscriptions are handled by the app store. Google Play or Apple processes the payment. We receive a token that says "this device is premium." We never see your credit card, name, or email. Privacy even in billing.
