About Sanket.Chat
Why Sanket.Chat
Most organisations discover their communication problem only after a breach, a regulator inquiry, or a whistleblower disclosure. Sanket.Chat is built so sensitive organisations never reach that point - giving decision makers a platform they can control, audit, brand, and deploy without surrendering data ownership to a foreign consumer platform.
What this means
The platform, in plain terms
Signal Protocol end-to-end encryption - plaintext never leaves the device, never transits unencrypted infrastructure
Zero-knowledge server architecture: your deployment stores ciphertext only, never readable content
Sovereign deployment options for organisations that cannot allow foreign jurisdiction over operational communication
Whitelabel and on-premise paths designed for defence forces, public institutions, governments, and critical operators
No advertising model, no user profiling, no third-party analytics that monetise your communication metadata
Admin controls for user provisioning, access revocation, group governance, and device trust
Zero-knowledge by design
Privacy architecture
Privacy is not a settings page - it is an architecture decision. Sanket avoids the advertising, profiling, and third-party analytics models that turn communication metadata into business intelligence for someone else. Your message content, group structure, and communication patterns remain under your governance, not a platform provider's commercial model.

Security model
The security model keeps plaintext outside the server trust boundary at every point: in transit, at rest, and under administrative access. Organisations can choose the deployment model - cloud, whitelabel, or air-gapped on-premise - that matches their risk profile without sacrificing the encryption guarantee.

Frequently asked questions
What makes Sanket.Chat different from Signal or WhatsApp?
Sanket is built for organisations, not individuals. Unlike Signal or WhatsApp, Sanket gives administrators control over user provisioning, group membership, access revocation, device trust, and deployment environment. The encryption is the same class - Signal Protocol - but the governance layer is purpose-built for institutional use.
Can Sanket be deployed on our own infrastructure?
Yes. Sanket.Work supports whitelabel cloud deployment on approved infrastructure. Sanket.Enterprise is designed for fully on-premise or air-gapped deployment with no dependency on foreign cloud services or external certificate authorities.
Does Sanket collect any communication data for analytics or advertising?
No. Sanket has no advertising model and no user profiling. The platform is designed around a zero-knowledge server architecture where the server stores only encrypted content. There are no third-party analytics integrations in the application.
Who is Sanket built for?
Sanket is purpose-built for organisations that treat communication security as a mission-critical requirement - defence forces, government departments, public institutions, hospitals, financial services firms, and any organisation replacing consumer app risk with institutional governance.
How does Sanket handle encryption key management?
Encryption keys are generated and stored on the user's device. The server never holds private keys. Signal Protocol's Double Ratchet key derivation means each message session generates ephemeral keys, providing Perfect Forward Secrecy - a compromised key cannot decrypt past messages.
