Your files are read in this browser and are not uploaded. The engine is downloaded once from krusgraph.com (15 MB unpacked, about 7 MB over the network) and runs here. The page sends only two anonymous events to krusgraph.com, that the engine has loaded and that a check is done, with no file contents, file names or table names.

Measured on “A total that doubles”, from opening the page to the result (Chromium, 28 October 2026): about 13.5 s the first time on a 5 Mbit/s line, 5.5 s on 20 Mbit/s, and 2.5 s once the engine is in the browser's cache. With your own files, choosing them is most of the two minutes.
