Relays + Messages That Evaporate by Design
No corporate servers. No blockchains. No metadata. Your infrastructure, your rules, your privacy.
Why LetUsMsg
Ephemeral First
All data stored in RAM, automatically purged on shutdown. Relays self-destruct and respawn every ~7 days.
Local First
Hyper-local messaging is possible — messages never leave your building. Deploy on your own network.
Post-Quantum Crypto
All latest Post-Quantum ciphers — including experimental — available for your cipher chain.
Zero Metadata
Relays never learn who you are. Only anonymous channel UUIDs. No logs, no analytics, no traces.
Configurable Encryption
Choose the cipher-chain and number of encryption rounds per chat group. Your security, your rules.
Deploy Anywhere
One static binary deployable on K3s, Docker, or bare metal. No databases, no cloud dependencies.
How It Works
Install Client
Grab the client for your platform: iOS, Android, macOS, Windows, or Linux.
Deploy a Relay
Lightweight static binary runs entirely in memory. Zero disk writes, zero dependencies.
Create a Chat Space
Each chat group forms its own anonymous, isolated identity with unique encryption.
Chat Securely
Share an invite code, connect clients. Messages flow through RAM, then vanish.
