Private communication infrastructure for modern organizations.
Your conversations belong to your organization, not the internet. Every message is encrypted on your own devices, so no one, not even us, can read it.

EncryptedBuilt for organizations that cannot afford to leak
This is not another social network.
Coveton has no feeds, no timelines, no stories, no followers and no public profiles. It is communication infrastructure your organization owns, closer to a secure operating system than a chat app.
Everything an organization needs to talk privately.
A complete, encrypted communication layer (messaging, voice, files, rooms and governance) without a single line of plaintext on our servers.
Zero-knowledge by design
Every message is encrypted on-device. Ciphertext is all our servers ever store. We cannot read your conversations, and neither can anyone who compromises us.
Organization-native
Organizations, teams, departments, roles and permissions are first-class. Onboard a whole firm in minutes with RBAC and invite links.
Encrypted messaging
One-to-one and group chats with reactions, edits, deletions, encrypted voice notes and encrypted file sharing, all end-to-end protected.
Self-destruct & tamper alerts
Messages can vanish on a timer. And the moment someone screenshots, copies or forwards a message, everyone in the conversation is notified, so nothing leaves a chat quietly.
Device authorization
Every device is explicitly authorized. Link a new device by scanning a QR code, review login history, and revoke access with one tap.
Calls & ephemeral rooms
Encrypted voice and video calls, plus temporary or anonymous audio rooms for a quick standup or a confidential conversation.
We built Coveton so we could never betray you.
Privacy is not a policy you have to trust. It is a property of the system. Here is the path a message takes.
Encrypted on your device
Your device generates the keys and encrypts the message before it ever leaves. Private keys are never transmitted.
Routed as ciphertext
Our servers store and deliver unreadable ciphertext. There is no key on our side that could decrypt it.
Decrypted only by the recipient
Only an authorized recipient device holds the key to read the message. Decryption never happens on a server.
What Coveton’s servers store
8f3a91c0e7d4…b2e6f1a4c9d8e0773a6b1f5c2d9e84a0f7c3b6e1d5a2…4e9f0c1
Unreadable ciphertext. No key on our side.
What your recipient sees
“Sealed filing is ready. Sending the encrypted draft now.”
Decrypted on their authorized device, and nowhere else.
We never invent encryption. Coveton is built on proven, independently audited cryptography, the same kind trusted to protect the most sensitive communication in the world.
Trust, by construction.
Every layer is designed so that compromising Coveton gives an attacker ciphertext and nothing more.
Keys never leave the device
Private keys are generated and stored only on your devices. They are never transmitted to or stored on Coveton servers.
Servers never decrypt
Our infrastructure routes and stores ciphertext. Decryption happens exclusively on authorized client devices.
Proven cryptography
We build on proven, independently audited encryption. We never invent our own; the boring, well-tested path is the safe one.
Tamper-evident audit logs
Administrative actions are recorded in append-only audit logs. See who did what and when, without ever exposing message content.
The honest answers.
If it is about privacy, we would rather over-explain than have you guess.
Yes. The Free plan gives individuals and small groups unlimited end-to-end encrypted messaging and voice notes at no cost, with up to 2 linked devices and 500 MB of encrypted media storage. Text messages are tiny, so the storage limit really only applies to photos, videos and files. Pro unlocks calls, tamper alerts (screenshot, copy and forward notifications), unlimited devices and much more storage.
Encrypted media (photos, videos, voice notes, files) is stored as ciphertext so it can sync across your devices. Because we pay for that cloud storage and never offset it with ads, each plan includes a fair media allowance: 500 MB on Free, 20 GB on Pro, 500 GB per user on Business, and custom on Enterprise. You can upgrade at any time, and most media also lives on your own devices.
It means Coveton has no technical ability to read your messages. Encryption keys are generated and held on your devices; our servers only ever see encrypted ciphertext. Even under subpoena, we cannot produce readable conversation content because we never possess it.
No. Coveton has no feeds, timelines, stories, followers, public profiles or likes. It is private communication for people and organizations, closer to a secure operating system than a social app.
Coveton uses proven, independently audited encryption that is trusted to protect billions of private conversations around the world. We never build encryption from scratch, because relying on cryptography that security experts have tested for years is far safer than inventing something new.
No. Administrators manage membership, devices, billing and policy, but message content remains end-to-end encrypted between participants. Admin power stops at metadata and governance, never plaintext.
Revoke it instantly from any other authorized device or from the admin dashboard. Because keys live on devices, removing a device cuts off its access immediately. You can link a new device by scanning a QR code from your phone.
Free is free forever. Pro and Business include a 14-day free trial with no credit card required. Custom plans are negotiated with our sales team and billed by invoice.
