HushHush — secret hidden messenger
Hand someone your phone. They can't prove you talk to anyone.
Other apps hide what you said. Hush hides that there's anyone to say it to. The home screen is a keypad — every chat stays hidden behind its own 6-digit code.
Free · No phone number needed · iOS & Android
Nothing on screen admits a conversation exists
No contact list. No conversation list. No master unlock. An app holding zero chats looks identical to one holding a hundred.
How Hush works
Four design choices make the promise literally true. Remove any one and it collapses — so Hush is built on all four.
The home screen is a keypad
No list, no thread, no badge. Nothing on screen admits a conversation exists — because nothing is listed anywhere.
One code, one person
You choose a unique 6-digit code per contact. There is no master key, so revealing one code exposes exactly one chat — never the rest.
A wrong code shows nothing
No error, no hint. An empty app and a full app look identical from the outside. Failed attempts are logged to Security Alerts for 48 hours.
No phone number
Accounts are username-only — like alex.42. Hush is a separate, deniable channel, not a directory of your real contacts.
"One code, one person. No master key. Wrong code — nothing happens."
What Hush is not
Privacy tools earn trust by being precise about their limits. Here is exactly where Hush's promise ends.
Not encryption
Hush is invisibility, not encryption. It doesn't promise the strongest adversary in the world can't read your data — it promises a person holding your phone can't tell who, if anyone, you talk to.
Not anonymity from the network
No phone number means no phone number — a username-only account. It does not make you anonymous to your carrier, your network, or the service itself.
No passcode recovery — on purpose
There is no "forgot passcode" option, because recovery flows are the back door every social-engineering attack walks through. A forgotten code is gone. "I can't open it" can be true.
Built for one adversary
The person physically holding your unlocked phone. Against network-level or forensic adversaries, Hush is honestly the wrong tool — and says so.
Don't believe it? Try it in 60 seconds
The whole claim is testable on your own phone, for free, before you tell anyone anything.
- Download Hush free. No phone number, no email — pick a username and you're in.
- Look at the home screen. Just a keypad. No chats, no names, no hint that anything is inside.
- Type 111111. A demo chat with Echo Bot appears out of nowhere. That's how every hidden chat works.

How do I hide messages from one specific person?
In Hush, every contact lives behind their own 6-digit code that you choose. Enter the code, the chat appears; leave the chat, it disappears again. There is no contact list, so hiding one person never means locking your whole phone. Learn more →
Is there a messaging app that doesn't need a phone number?
Yes. Hush accounts are created without a phone number or email — you pick a username like alex.42 and connect by sharing it or an invite link. Nothing in the app ties a chat to your number. Learn more →
Can I put a password on my messages?
Most apps lock chats behind one visible lock — which shows anyone holding the phone that something is locked. Hush works differently: each contact has their own code, there is no master unlock, and a wrong code opens nothing and shows no lock at all. Learn more →
How do I hide text messages on an iPhone?
iOS can hide alerts and lock apps behind Face ID, but the conversation itself stays in your message list. Hush keeps whole conversations off the surface entirely: its home screen is a keypad, and chats only exist on screen after you type the right code. Learn more →
How do I stop message previews showing on my lock screen?
You can turn off previews per app in iOS and Android notification settings. Hush is stealth-first by default: notifications never show a name or message content on your lock screen. Learn more →
Do disappearing messages really disappear?
Expired messages are deleted, but in most apps the conversation itself — the name, the thread — stays visible. Hush combines message expiry (1h to 48h) with a thread that is never visible in the first place. Learn more →
What's the best secret messaging app for iPhone?
Judge any secret messaging app on four points: does a chat list exist, is there one master lock or a code per chat, what happens on a wrong code, and does it need your phone number. Hush was built around exactly those four. Learn more →
What about secret messaging on Android?
Hush runs on Android and iOS, and a hidden chat works across both. The same rules apply: keypad-only home screen, per-contact codes, silent failure on a wrong code, no phone number required. Learn more →
Do secret apps that look like a calculator actually work?
Calculator vaults work until someone recognizes the trick — and a discovered disguise is itself evidence. Hush takes the opposite approach: no disguise, just a keypad that reveals nothing at all, whether it holds zero chats or a hundred. Learn more →
Is there a private texting app for couples?
Hush is built for exactly two people who both want one conversation kept private. Both install Hush, connect by username, choose codes — and on both phones the chat is invisible until its code is typed. Learn more →
Is Hush encrypted?
Hush is invisibility, not encryption. Messages use standard transport security (TLS), but Hush does not claim end-to-end encryption and is not the right tool against network or forensic adversaries. What it does is different: a person holding your unlocked phone cannot tell who, if anyone, you talk to.
What happens if someone types the wrong code?
Nothing visible. No error, no hint, no locked-out screen — an empty app and a full one look identical. The failed attempt is logged, and you can review attempts from the last 48 hours in Security Alerts.
What if I forget a contact's code?
That contact is gone — there is no recovery, by design. A "forgot passcode" flow would be a back door for anyone pressuring you to open the app. No recovery also means "I can't open it" can be literally true.
Your conversations are nobody's business but yours
Free to use. No phone number. Six digits between any curious pair of eyes and absolutely nothing to find.
