Privacy Policy

Last updated: March 10, 2026

1. Your Data Stays Yours

CSV GPT is built with a privacy-first architecture. The core value of our service is that your data never leaves your device.

When you upload a CSV file to CSV GPT, it is processed entirely within your web browser using DuckDB WASM. We do not upload, transmit, store, or have access to your raw tabular data.

2. Interaction with AI Providers

To enable natural language querying, CSV GPT sends only your table schema (column names and data types) and your chat messages/questions to the configured Large Language Model (LLM) provider.

We strongly recommend reviewing the privacy policy of the LLM provider you choose to connect (e.g., OpenAI). If you require ultimate privacy, CSV GPT supports connections to locally hosted models (e.g., via Ollama, LM Studio, or llama.cpp), meaning zero data leaves your local network.

3. Local Storage

We use your browser's local storage to save your application preferences, API keys (if applicable), and chat history. This data is stored locally on your device and is not synchronized to any central server. Clearing your browser data will delete this information.

4. Analytics & Telemetry

The CSV GPT application does not utilize tracking cookies or invasive analytics tools to monitor your data analysis behavior. We respect your workspace.

5. Contact

Because CSV GPT operates entirely client-side, we do not have a centralized support team to manage or delete your data (since we don't have it). For bugs or codebase inquiries, please refer to our GitHub repository.
