DPDP Shield

IThe ground

The brief.

India's DPDP Act 2023 calls for a clear, auditable approach to hospital data protection. Promptly AI envisioned a private tool that could connect directly to hospital databases, review compliance readiness, and produce legal-grade audit reports—with all processing kept on-premise.

IIThe plan

Our response.

We created DPDP Shield—an offline-first desktop application that connects to hospital databases (PostgreSQL, MySQL, MSSQL, Oracle, SQLite) in read-only mode and runs 36 readiness checks across 14 DPDP rules. The app generates exposure reports in ₹ Crore, practical fix guides with copyable SQL examples, and evidence PDFs for confident compliance planning. A companion Next.js website handles downloads and licensing, while all hospital data stays on-premise.

Brick by brick.

Course 01
Compliance Engine
Designed 36 database-level checks across 14 DPDP rules — covering consent, encryption, data minimisation, retention, access control, audit logs, breach readiness, children's data, and third-party sharing.
Course 02
Multi-Database Support
Built read-only connectors for PostgreSQL, MySQL, MSSQL, Oracle, and SQLite using a Python sidecar, with query adaptation for each database dialect.
Course 03
Exposure & Reporting System
Implemented exposure modelling in ₹ Crore with min–max ranges based on the DPDP Act schedule, alongside PDF audit reports, CSV export, and evidence-of-compliance PDFs for clear planning.
Course 04
Offline-First Architecture
Built with Tauri 2 + SvelteKit 5 + Rust + Python sidecar. Machine-locked licensing, keychain password storage, zero telemetry — nothing leaves the hospital's network.
