About Signal
Closing the UX gap while pushing the crypto frontier.
Signal is running two parallel programs: a cryptographic agenda (post-quantum ratchet, defenses against Microsoft Recall) and a long-overdue UX parity push (secure backups, polls, pinned messages, group labels). The product has matured past pure privacy infrastructure and now ships features mainstream users have asked for for years. Each direction reinforces the brand: still the most paranoid messenger, but no longer the one that loses your chat history when your phone breaks.
