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.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Calls now show every step — Calling, Ringing, Connecting — with a gentle ringback tone and a timer once you're talking. The screens after a call ends no longer pile up.
• Message and call notifications reach your phone.
• Add someone by QR and you're straight in the chat with a friendly hello. Share your code as an image, or scan one from Photos or Files.
• Post a status or set your photo straight from the camera.
• Picking and editing photos is much faster, and portrait photos stay upright.
• Stronger account security behind the scenes.
