You shouldn't have to worry private messages stick around. With CoverMsg, they won't.
Everything you type today outlives the conversation it was part of.
Not because someone's listening — because nothing you send actually disappears. It sits on a phone, a server, a backup you forgot about, long after the moment it was meant for has passed.
Encrypted isn't the same as gone. Most messages you've ever sent still exist — readable, on phones and servers you don't control.
Here's what changes.
A one-time hidden message, sealed inside an ordinary one. Hold to reveal. Read once. Gone for good. Try it below.
To anyone glancing at the screen, that conversation is all there is.
OPENED ONCE. GONE EVERYWHERE.The hidden message lived for a few seconds — the ordinary cover conversation above is all that remains, and all anyone will ever see.
Sealed. Sent. Read once. Gone.
Here's what just happened, step by step.
Write the cover — an ordinary message. Seal a hidden message inside.
The hidden message is locked on your phone before it ever leaves. The moment you send, your copy is destroyed — even you can't reopen it.
What they see looks completely ordinary.
No lock icons. No banner. Not even a tint — at rest, the thread is pixel-identical to one carrying nothing hidden at all.
They press and hold to reveal it — once.
It appears, then destroys itself everywhere — their phone and the sealed queue on our server. Your copy was already gone the moment you hit send. The cover message stays in the chat, ordinary as ever.
1The hidden message is sealed on your phone — your copy destroyed at send.
2Queued as a locked blob our server has no key to open.
3Delivered — and deleted from the server that instant.
Revealed once, then gone everywhere. Only the cover message remains on your two phones.
We're not Signal. We're not trying to be.
Signal stops interception, and stops it well. But interception was solved years ago. What wasn't: the readable copy that piles up in chat history on both phones, and an app whose very presence announces you have something to hide.
A hidden message sealed inside an ordinary one. A thread that marks nothing. A readable life measured in seconds. No other messenger does any of it.
Everything we store fits right here.
Most apps show you a privacy policy. We can show you the whole inventory — there is nothing else to leak, subpoena, or steal.
Nothing waits forever. A hidden message sits sealed and unreadable in the delivery queue — never decrypted, never backed up. Delivered, it's gone at that instant. Left unopened, it expires after 7 days, then it's gone too.
No cloud, no sync. Your cover conversation passes through only to reach the other phone — it's never retained, backed up, or archived anywhere, by us, Apple, Google, or anyone else. Once delivered, it exists only on your two phones. The hidden message, while it's in transit, exists only as a sealed blob we hold no key to — not backed up, not readable, and never kept past delivery or its 7-day expiry.
No ads to feed. CoverMsg is funded by subscriptions, not advertising. There is no ad profile, and nothing readable to build one from.
Identity stops at an email. It must be an address you actually receive, but it never has to reveal who you are — and it attaches to an account code, never to a conversation.
Take back what's yours.
Nothing left sitting in a thread to resurface later. Nothing on the screen that looks like it's hiding something. And nothing left depending on the other person remembering to delete it — it's just not there anymore, for either of you.
