End-to-end encrypted device sync — keys stay with you

Signal's and WhatsApp's familiar E2EE pattern, extended to AI memory, embeddings and documents. A server cannot read your data, even in theory.

Device-held keysForward secrecyAuditable

The word 'encrypted' can mean anything from transport-layer encryption (TLS) to real end-to-end encryption (E2EE). Sinun AI uses the latter: only your devices see plaintext, and keys never leave them.

What's encrypted

Every conversation, document, embedding and memory variable is encrypted before sync. Metadata is minimised; e.g. a message timestamp is stored, but the content is invisible to any server.

Key management

Devices pair securely (QR or manual key exchange). Your recovery phrase lives in your own password manager. We cannot recover data if you lose every device and the recovery phrase — this is the flip side of real E2EE.

Frequently asked

Is this the same as Signal?
Same principle: E2EE, per-device keys, forward secrecy. Different domain: we sync AI memory rather than human messages.
