Input is processed locally and a draft is saved automatically in this browser profile when storage is available. Reset to sample clears that draft; Pro history has its own clear button. A state link encodes your inputs in its URL: share only non-sensitive rows. Browser history, clipboard and anyone receiving the link may retain it. Optional AI use below leaves this device; it is not required.
Data note: Everything runs in this browser tab on the passage clearance strip: your building passage | measured clear width mm | frame obstruction mm stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
