Currently, Y Communicator is designed for single-device use to maintain maximum security. Your encryption keys are stored only on your device. Multi-device support is planned for future releases.
Since Y Communicator uses zero-knowledge architecture, your messages and encryption keys are stored only on your device. If you lose your device or delete the app, your message history cannot be recovered. We recommend backing up important information separately.
No. Y Communicator does not backup your messages to any cloud service. All messages are stored locally on your device and encrypted. This ensures that only you have access to your conversations.
Post-quantum encryption uses cryptographic algorithms that are resistant to attacks from future quantum computers. Y Communicator implements NIST-approved post-quantum algorithms to ensure your messages remain secure even as computing technology advances.
