Analyze CSV, Excel, Parquet and databases using natural language — while your raw records stay 100% on your machine.
How natural language Text-to-SQL operates without ever transmitting sensitive records or PII outside your RAM perimeter.
Enterprise security teams and independent developers ask: "How do I know my data is safe?" Here is our audited network transmission matrix.
| Data Category | Leaves Device? | Where Does It Go & Why? |
|---|---|---|
| 📁 CSV / Excel / Parquet raw data rows | ❌ NO | Processed 100% locally in RAM by native DuckDB. Never transmitted across the network. |
| 👤 Customer records & Sensitive PII / PHI | ❌ NO | Zero raw customer records or health info ever reach external APIs or LLMs. |
| 📊 Query execution results & aggregates | ❌ NO | Result sets stay strictly inside your local client process memory and browser canvas. |
| 📋 Table & Column Names | ⚠️ Schema Only | Sent to LLM only when AI mode is queried to construct the SQL statement (e.g. region, sales). |
| 🏷️ Column Data Types (INT, VARCHAR, DATE) | ⚠️ Schema Only | Required for LLM to produce syntactically valid DuckDB SQL casts and aggregations. |
| 🤖 AI-Synthesized SQL Query | ⬇️ Inbound Only | Returned to your device from the LLM, verified by local AST SELECT-only sandbox before execution. |
| 🔒 Air-Gapped Mode (Local Ollama / Direct SQL) | ❌ ZERO BYTES | 100% Offline. Zero network requests. Operates completely air-gapped without internet. |

"I built VeilAnalytics to solve a fundamental dilemma: data analysts want the productivity of AI text-to-SQL, but security teams cannot allow confidential raw records to be ingested by cloud LLM vendors. By combining local embedded DuckDB C++ execution with zero-raw-data metadata prompt engineering, VeilAnalytics provides instant sub-50ms analytics while guaranteeing 100% data isolation."
