End-to-end messaging
Vavus messaging uses the Signal Protocol so message content is end-to-end encrypted between participants.
Encrypted translation
Private translation that protects what you say
Vavus AI is built for translation workflows where privacy matters: Signal Protocol messaging, client-side encrypted history, encrypted documents and audio, data export and deletion paths, and on-prem deployment for teams that need processing inside their own boundary.
Fast evaluator answer
- Best fit
- Users and teams translating sensitive conversations, documents, messages, calls, and healthcare or enterprise workflows.
- Ask about
- Whether the workflow is messaging, persisted history, document translation, live speech, or regulated on-prem processing.
- Key distinction
- End-to-end messaging is different from client-side encrypted storage and from live AI processing.

Why it matters
Privacy claims are easy. Private translation needs a real architecture.
Translation can include sensitive medical, legal, family, financial, or business context. Vavus AI separates message privacy, stored-content encryption, real-time processing, and deployment boundaries so buyers can evaluate the exact risk model.
Encrypted stored content
New translation history, documents, and audio uploads are encrypted client-side before leaving the device, so stored content is ciphertext for new artifacts.
Deployment boundary
Enterprise and healthcare customers can choose dedicated Google Cloud deployment path or on-premises deployment so processing happens inside an approved environment.
Workflow
What is encrypted, and where
The honest model matters. Some translation data can be encrypted end-to-end, some is encrypted client-side before storage, and real-time speech workflows must be processed briefly to produce translation output.
1. Messages
Translated messaging rides on Signal Protocol end-to-end encryption. Vavus does not need plaintext message content to store messages.
2. History and files
New history, documents, and audio uploads are encrypted client-side with per-artifact keys wrapped by the user account key.
3. Live processing
Real-time speech translation is briefly plaintext in memory while speech-to-text, translation, and text-to-speech run, then approved outputs can be encrypted before storage.
4. On-prem path
When cloud processing is not acceptable, regulated customers can run speech, translation, and voice output inside their own perimeter.
Guardrails
Privacy claims without hand-waving
No serious AI translator should pretend every step of live speech translation is magic-box end-to-end encryption. Vavus AI is explicit: messaging is end-to-end encrypted, stored artifacts are client-side encrypted for new content, network traffic is TLS-protected, and on-prem deployment is available when processing location matters.
- Messaging uses Signal Protocol end-to-end encryption.
- New history, documents, and audio uploads are encrypted client-side before storage.
- Real-time speech must be processed briefly in memory to generate translations.
- Legacy server-side encrypted content remains read-only under older encryption behavior.
- On-premises deployment can keep processing inside the customer boundary.

Direct answers for evaluators.
Is Vavus AI an end-to-end encrypted translator?+
Vavus AI messaging is end-to-end encrypted with Signal Protocol. New translation history, documents, and audio uploads are encrypted client-side before storage. Real-time speech translation must be briefly processed in memory to produce speech-to-text, translation, and text-to-speech output.
What does client-side encrypted translation mean?+
Client-side encrypted translation means the artifact is encrypted on the user device before it is stored by the server. For new history, documents, and audio uploads, Vavus stores ciphertext rather than plaintext content.
Does Vavus AI see plaintext during live voice translation?+
Live voice translation requires temporary plaintext processing in memory while speech-to-text, translation, and text-to-speech run. Approved outputs can then be encrypted before storage. Customers that cannot allow cloud processing can evaluate the on-premises deployment path.
Is Vavus AI a private translation app for healthcare?+
For healthcare use, Vavus AI offers BAA-backed onboarding for approved workflows, zero PHI in application logs by design, healthcare session controls, 6-year audit retention, and an on-premises deployment option.
Can Vavus AI run translation without sending data to the cloud?+
Yes, for Enterprise and Healthcare deployments. Vavus AI can run speech-to-text, translation, and text-to-speech fully on-premises with no outbound network calls when the customer requires that boundary.
Does Vavus AI support data export and deletion?+
Yes. Authenticated users can request data export and account deletion. Some audit records may be retained for legal, security, billing, or healthcare compliance reasons, and those records are metadata-only rather than translation content.
