Privacy Policy
Last updated: June 2, 2026
viewparquet is operated by Kaladev Digital Private Limited. This policy describes how we handle information when you use our website and in-browser Parquet viewer.
Your files stay on your device
Parquet, GeoParquet, CSV, and JSON files you open are processed locally in your browser using DuckDB-WASM. We do not upload your datasets to our servers for viewing or SQL execution. You can verify this in your browser's developer tools Network tab while using the product.
Your privacy choices
On your first visit we ask how you'd like to help us improve the product. You can Allow all, Essential only, or use Customize to toggle each category below. None of these options ever send your file contents anywhere — your data stays in your browser regardless of what you choose.
Information we may collect
- Product analytics (optional) — if you consent, we load Google Analytics (measurement ID G-S2V3Q426KV) and Vercel Analytics to collect aggregated page views, referral sources, and feature usage. Neither receives your file contents.
- Error monitoring (essential) — we use Sentry to capture crash and error reports so we can keep the app working. This is part of the core service and does not include your file contents.
- Session replay & diagnostics (optional) — if you consent to diagnostics, Sentry additionally records anonymized session replays and may collect technical identifiers (such as your IP address) to help us reproduce and fix issues.
- AI assistant requests — when you use the optional AI features, query text and schema context may be sent to our API providers to generate SQL. Do not include secrets or personal data you are not permitted to share.
- Local storage — preferences (such as theme, cookie consent, and welcome modal state) and optionally saved file references in IndexedDB on your device only.
Third-party services
The app may load open-source runtime assets (for example DuckDB-WASM) from our CDN. Google Analytics processes data according to Google's Privacy Policy, Vercel Analytics according to Vercel's Privacy & Compliance policy, and Sentry according to Sentry's Privacy Policy. Third-party AI providers process assistant prompts according to their own policies when you invoke AI features.
