Frequently asked questions

Is my data safe?

Yes. Your Parquet files are processed entirely in your browser using WebAssembly. They never leave your machine — we don't even have a server to send them to.

What's limited in the free plan?

Only the number of files. You can load 1 file and run any SQL query on it — no row limits, no feature restrictions. You need Pro to load multiple files and JOIN them.

How large can my files be?

DuckDB can handle files up to ~1GB comfortably in most modern browsers. Larger files depend on your device's available RAM.

Can I cancel anytime?

Yes, you can cancel your Pro subscription at any time. You'll keep Pro access until the end of your billing period.
