Post-quantum secure messaging.
Exchange keys in person. Message from anywhere.
Traditional messaging apps rely on centralized servers to exchange encryption keys. You're trusting a company with your most private communications.
Worse, quantum computers will soon break the encryption protecting today's messages. Data harvested now can be decrypted later.
Meet your contact face-to-face. Scan each other's QR codes to exchange public keys directly.
Your private keys never leave your device. No server ever sees them. No company can access your messages.
Send encrypted messages from anywhere. Only your contact can decrypt them.
Meet in the Park uses NIST-approved post-quantum cryptography standards:
FIPS 203 Module-Lattice Key Encapsulation. Securely establishes shared secrets resistant to quantum attacks.
FIPS 204 Module-Lattice Digital Signatures. Authenticates messages so you know who sent them.
Every message is encrypted with AES-256-GCM and signed. If anyone tampers with a message, you'll know.
The name reflects the core principle: trust is established in person, not through servers.
When you meet someone in a park and exchange keys face-to-face, there's no man-in-the-middle. No company policy. No government request. Just you and your contact.
That moment of physical presence creates an unbreakable chain of trust for all future communication.
We're building in public. Here's where we are.
We're looking for privacy-conscious individuals who want to help test post-quantum secure messaging. You'll need to understand that this is alpha software and be willing to provide feedback.
