LADON messenger is the iPhone messenger that knows nothing about you. No phone number. No account. No trace. Not WhatsApp, not a hacker, not a government — not even us. Just the two of you.

LADON messenger — an end-to-end encrypted chat on iPhone

Try it: who can read this message?

"Yes! Want to meet at 5:30 at the café?" ENCRYPTED

→ Mira: Sure — this message is meant for her.

Why this matters

Encryption alone isn't enough.

To surveil you, someone doesn't even need to read your messages. Who with whom, when and how often — that often reveals more than the content itself.

ATTACK

"Who's talking to whom?"

Even without the content, someone can build a full profile of you — just from your connections.

Sender sealed

Patterns in the data flow

Even encrypted traffic gives you away: its rhythm shows exactly when a real conversation is happening.

Hidden by cover traffic

ATTACK

"Store today, crack later"

Today's data gets archived. In a few years, quantum computers decrypt it all at once.

Quantum-safe today

Identity linked

A phone number, email or device ID instantly links your "private" account to your real name.

No identity to link

Chat control · 2026

The EU is debating scanning private messages. Here, there's nothing to scan.

Since July 2026, providers in the EU may once again scan messages without any suspicion — and the follow-up law on the table would make scanning mandatory. LADON messenger was built for exactly this moment: our servers see only noise. No text, no sender, nothing to hand over.

Chat control, explained simply

Under the hood

Here's what happens to your message.

Between your keyboard and your contact's screen, every message goes through this — automatically, before it ever leaves your phone. No setup, no buttons.

Your message "Hey, want to meet at 5:30?"

↓

01Locked on your phone

Turned into code only your contact can open — before it leaves.

02A new key each time

Every message gets its own key. Crack one, the rest stay sealed.

03Sender erased

The server passes it on without ever learning who sent it.

04Buried in noise

Padded to a fixed size and hidden among fake messages over Tor.

LADON messenger is a young project and has not yet had an external audit. Signal remains, for most users, the gold standard. Our goal: to raise the technical bar beyond Signal — audits and open source are planned.

Who it's for

Built for people whose words carry weight. And for everyone who thinks private is private.

Journalists protecting a source. Lawyers and doctors bound to secrecy. Activists in the wrong country at the wrong time. And you — because a private life shouldn't be a privilege for tech professionals. You don't need a reason to close your curtains.

FAQ

Questions you should ask every messenger.

Technically, LADON messenger has protection layers Signal doesn't offer today: cover traffic, split knowledge across two servers, a hidden sender, quantum-safe signatures. Signal, in turn, has years of independent audits and hundreds of millions of users. Security is more than code — it's trust, scrutiny and reach. For most users, Signal remains the right choice today.

If someone records your encrypted messages today, they will likely be able to decrypt them with quantum computers within a few years. LADON messenger combines classical and quantum-safe encryption. So messages you send today stay private even in 2035.

Your keys exist only on your device. There's no cloud backup and no recovery service. You'd have to scan new QR codes with your contacts. That's inconvenient — but no one can steal your keys from a cloud.

No. Neither we nor the server operator can decrypt anything. A seizure turns up only encrypted data packets — with no information about who sent them or where they're going.

LADON messenger automatically sends fake messages at regular intervals through the same line as your real ones. An observer can't tell what's real and what's just camouflage.

From you — through a simple monthly subscription. That's the point: when you pay for the app, you're the customer, not the product. No ads, no trackers, no selling your data. Ever.

A small team's focus: get one platform right before tackling the next. Android is on the roadmap.
