Privacy & usage measurement

We count page views, calculator interactions, print clicks and pilot-interest clicks to improve these tools. Our application stores daily totals by event, tool and broad referral category. We do not send your calculator inputs, camera names, project details, email address, full referring URL or IP address to this measurement database.

A temporary browser session flag prevents repeated keystrokes from counting as separate calculator uses. It is not sent to the server. Measurement respects Do Not Track and Global Privacy Control where available. Hosting providers may process ordinary request logs for service operation.

A calculator use means someone interacted with its inputs. These counts are approximate and do not prove a unique human visitor, completed project or sale. Tracking begins with this release; earlier use is unknown.
