Lyra Secure Messenger

Lyra is a post-quantum secure messenger that keeps your conversations private — today and against tomorrow's quantum computers.

FEATURES • End-to-end encrypted messaging with post-quantum protection • Encrypted voice and video calls • Send files, photos, and voice messages — all encrypted • Direct messages and group conversations • Device verification so you know who you're really talking to • No ads, no tracking, and we never read your messages Lyra is built by URSA Mobile for people who need serious, future-proof privacy for their conversations.
