What is encrypted and what is not yet

Honestly, without marketing: personal and group messages, files and voice protected by end-to-end encryption (E2E) - the server sees only the ciphertext, the keys do not leave your device; added post-quantum layer (ML-KEM-768). Calls they work on standard WebRTC encryption: the media stream is encrypted point-to-point (DTLS-SRTP), but end-to-end encryption of the signaling itself is still being finalized - this is protection against passive eavesdropping, but not full E2E like messages. There has not yet been an independent external audit of cryptography.

What is especially important to check
