Built so no one, not even us, can read your messages.
Coveton is a private, end-to-end encrypted messenger. Your keys live on your device, our servers only ever see ciphertext, and privacy is enforced by the architecture, not a promise.
Privacy enforced by design, not by policy.
Every layer of Coveton is built to keep your conversations yours.
End-to-end encrypted by default
Every chat, call, voice note, status and file is encrypted on your device before it leaves it and only decrypted on the device it is meant for. Encryption is not a setting you turn on, it is how Coveton works.
Zero-knowledge, keys never leave the device
Your private keys are generated and stay on your devices. We never hold them, so we cannot read your messages, hand them over, or lose them in a breach. Your account, not our servers, holds the keys.
Servers only ever see ciphertext
Coveton servers route encrypted data they cannot open. There is no readable copy of your conversations anywhere on our infrastructure, by design.
Proven, audited cryptography
We build on well-established, battle-tested cryptographic primitives rather than inventing our own. The unglamorous, reviewed path is the safe one.
No ads, no tracking, no profiling
Coveton makes money from subscriptions, not from you. There are no ads, no trackers, no engagement loops and nothing about your conversations is mined or sold.
Tamper alerts
Know when someone copies, forwards or screenshots a message you sent. Coveton surfaces these events so you keep awareness of what happens to your words after they leave you.
App lock
Lock Coveton behind a PIN so a glance at your phone never becomes a glance at your conversations.
Disappearing messages
Set messages to delete themselves on a timer, and send view-once photos and videos that vanish after a single look.
Three principles we will not bend.
Privacy is structural
We do not ask you to trust a policy. We build systems where reading your messages is impossible, both for attackers and for us.
Boring cryptography
We use audited, standard primitives and never roll our own encryption. Predictable beats clever when your secrets are on the line.
Least data, always
We collect the minimum needed to deliver a message and nothing that lets us read it. What we never store, we can never leak.
