Secure. Simple. Fast. QSafeChat is a free messenger for everyone: chat, share photos and videos, post statuses and make voice and video calls — all end-to-end encrypted, with no ads and nothing to set up. WHY "QUANTUM-SAFE"? Most encrypted apps today rely on math that a large enough quantum computer is expected to break. Someone could record your encrypted messages now and try to open them years later — "harvest now, decrypt later". QSafeChat protects against that with post-quantum cryptography (PQC): new encryption algorithms designed to resist quantum computers, standardized by the U.S. National Institute of Standards and Technology (NIST). Every direct conversation starts with a PQXDH key agreement using ML-KEM and continues with a Double Ratchet, so your messages stay private today and tomorrow. SIMPLE TO START • Pick a name and an @handle — that's your identity • Add people by scanning their QR code (or sharing yours as an image), or by @handle • Your phone number is used once to check you are a real person, then discarded — never stored by us, never searchable FAST AND FRIENDLY • Messages, photos, videos, voice notes and documents • Voice and video calls, encrypted on your device • Statuses for your contacts, reactions, replies and disappearing messages • English and Turkish WHAT STAYS PRIVATE • Direct messages, media, statuses and calls are end-to-end encrypted • Your contact list never leaves your device • Everything the app keeps on your phone lives in an encrypted vault, behind an optional PIN or Face ID • No ads, no trackers, no analytics HONEST BY DESIGN Every conversation is labeled truthfully: group chats are currently protected in transit while group end-to-end encryption is in development. INDEPENDENT INFRASTRUCTURE QSafeChat runs on its own servers — no third-party messaging cloud in between. The server only sees sealed envelopes and the routing data needed to deliver them, and you can delete your account and its server-side data at any time from Settings. FREE FOR EVERYONE No invitation, no waiting list, no subscriptions, no in-app purchases. Questions or feedback: mert@qsaferoom.com
