CalcSimply is supported by display advertising. You may see ads on some pages — these are served by Google AdSense and similar networks. We do not show intrusive pop-ups or interstitials.
We do not sell your data, and your inputs are never sent to any server. The ads are the only thing that keeps the lights on.
