I built Quldra (www.quldra.com) completely from the ground up with one clear goal: to create a private and secure messaging app that is as ready as possible for the potential arrival of quantum computers. One thing that mattered especially to me was making sure that the usual “harvest now, decrypt later” risk would not apply to the solution I built. Key points: - Post-quantum end-to-end encryption (ML-KEM-768 + ChaCha20-Poly1305) – each conversation gets its own random key. - One device, one account – message history does not travel between devices. - No phone number, no email, no social media account – only a username is required. - iOS and Android apps, plus temporary browser chat capability.
