1. Overview

SamVault Ltd ("SamVault", "we", "us") is the data controller for personal data processed through the SamVault platform. We are registered in India and comply with applicable data protection legislation including the Information Technology Act 2000 and the Digital Personal Data Protection Act 2023 (DPDPA).

Zero-knowledge architecture: The content of documents you upload is protected with strong encryption. We do not have access to the content of your documents — only encrypted data is stored.

3. How We Use Your Data

We use your personal data only for the following purposes:

  • Providing the Service — authenticating you, storing and serving your encrypted documents, sending sharing notification emails.
  • Security and fraud prevention — detecting anomalous access patterns, maintaining audit trails, responding to security incidents.
  • Service communications — sending transactional emails (upload confirmations, share notifications, account alerts). These are not marketing emails and cannot be unsubscribed from while your account is active.
  • Service improvement — anonymised analytics to understand how users interact with the platform.
  • Legal obligations — complying with applicable law, court orders, or regulatory requirements.

We do not use your data for advertising, profiling, or automated decision-making with legal or similarly significant effects.

4. Encryption & Zero-Knowledge

SamVault uses a zero-knowledge encryption architecture. Here is what this means for your data:

  • Each user vault is protected by a unique encryption key generated at registration. It is never stored in a recoverable form.
  • A layered encryption system ensures each document is independently protected with its own key.
  • Document content is encrypted with AES-256-GCM before being stored. Only encrypted data reaches our storage systems.
In plain terms: Even if our database or storage were ever compromised, your document contents would remain unreadable. Your encryption key is never stored in a way that can be reconstructed by us or anyone else.
