1. Information We Collect & Local Processing

Infradigital CAD operates with a privacy-first, client-side engineering architecture. Any data files, Civil 3D LandXML exports, survey points (PENZD), alignment tables, BoQ spreadsheets, or coordinate files loaded into our engineering calculators are processed entirely locally within your web browser.

We never upload, transfer, or store your engineering designs, client CAD drawings, or raw coordinate data on external servers or third-party cloud storage. Your intellectual property and engineering files remain stored on your local device at all times.
