What We Collect

When you use Excelio in browser mode, your data files are processed entirely in your browser using DuckDB-WASM. We do not upload, store, or access your data files on our servers.

If you create an account, we store your email address (via Clerk authentication) and any workflows you explicitly save.

We use analytics (Posthog) to understand how features are used. This includes page views and feature usage — not your data content.

AI Features

When you use the AI assistant, your prompts and workflow context are sent to OpenAI's API to generate SQL queries. We do not send your actual data rows — only schema information (column names and types).

Data Security

All browser-mode processing happens locally. Saved workflows are stored in PostgreSQL with user-level isolation. We use HTTPS for all communications.
