Inputs are not stored

When a calculation runs, the relevant part of your model is sent to a stateless function, computed and returned. The request body is not stored, and error logs record only counts and error codes, never input values.

Public data lookups

Some tools can fill site data from coordinates (“Fill from coordinates”). Only when you press that button, the latitude and longitude, rounded to 0.1° (about 10 km), are sent through our server to the NASA POWER service, which returns climate averages. Nothing else from your inputs is sent, and the coordinates are not stored by RokBench. The NASA response may be cached by location to reduce load.

The Solar PV tool can also fill insolation from NREL PVWatts. Only when you press that button, the coordinates rounded to 0.01° (about 1 km), the mounting type and the tilt are sent through our server to the PVWatts service of the U.S. Department of Energy's National Laboratory of the Rockies (formerly NREL). Nothing else is sent, nothing is stored by RokBench, and the response may be cached by location.

Usage limits

To keep the service available and to prevent automated extraction, detailed contingency studies are limited per network per day. For that count only, your IP address is combined with the date and turned into a one-way hash; the count is kept under that hash and deleted automatically after about a day. The IP address itself is not stored, and nothing in the count identifies your model or inputs.

Your model lives in your browser

The Workbench keeps your model in this browser's memory and saves a recovery copy to this browser's local storage so a closed tab does not lose work. It never leaves your device unless you export it or run a calculation. Clearing site data removes it.
