Field notes
The photo workflow is described as checking head length, background, and shadows, then cropping for several document formats and online submission limits. The bill calculator accounts for uneven participation, such as someone leaving after the first round or not drinking, and provides a message stating who should pay whom. The homepage says tool inputs stay on the user's device; its problem-report form is the stated exception to its no-storage claim.
