Privacy Policy

Effective Date: 2/8/2026

At KooQuery, we prioritize your privacy above all else. Our core philosophy is Local-First, meaning your data stays on your device.

1. Data Collection & Usage

We do not collect, store, or transmit your CSV files or data content. All data processing happens locally on your machine using DuckDB-WASM (for Web) or our native engine (for Desktop).

We may collect anonymous usage statistics (e.g., number of app launches, crash reports) to improve stability and performance. This data is non-personally identifiable.

2. Local Storage

KooQuery uses your browser's IndexedDB and OPFS (Origin Private File System) to persist your workspace state and metadata. This data remains strictly within your browser environment.

3. Third-Party Services

We host our website and documentation on trusted platforms (e.g., Vercel, GitHub). These platforms may collect standard server logs (IP addresses, user agents) for security and analytics purposes.

4. Updates to this Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.

5. Developer

KooQuery is an open-source project developed by Junjie Huang.
