Not even we can read your messages. No phone number required. No tracking. Just pure, encrypted communication that syncs across all your devices.
The world's biggest messaging apps scan your conversations, contacts, and behavior to build advertising profiles. You're not the user — you're the product being sold to advertisers.
Most "encrypted" apps still require your phone number — linking your real identity to every message, every group, every call. Governments and corporations can trace you with a single number.
Some platforms claim encryption but keep a backdoor. Unencrypted backups, metadata logging, cloud copies they can access. If the company can read it, so can anyone who compromises them.
Billions of people trust their most intimate conversations to platforms that profit from reading them. We built PoSec because that's insane.
Every feature designed with one principle: you own your data.
X3DH key exchange + Double Ratchet. The same encryption used by Signal, but without requiring your phone number.
Server stores encrypted blobs only. We can't read your messages, see your contacts, or access your keys. Ever.
Your encrypted messages sync across all devices. Only your keys can decrypt them. Lose a device? Your data stays safe.
No phone number. No email. Your cryptographic key pair IS your identity. Truly anonymous, truly yours.
E2E encrypted group chats with Sender Key protocol. Broadcast channels for communities. All encrypted.
Hyperlocal social feed and anonymous discussion forums. Connect with people nearby or debate ideas globally.
From signup to encrypted conversation in under 30 seconds.
Pick a username. Your device generates a unique cryptographic key pair. No phone number, no email, no tracking.
12 words that unlock your identity on any device. Write them down. This is your master key — we never see it.
Every message is encrypted before it leaves your device. The server only sees encrypted blobs. Not even we can read them.
