What To-Do List App does, with a checked example
This is a task list that lives entirely in the browser you open it in. Each task takes a priority, a due date, and a category, and you arrange the rows by dragging them - the list does not sort itself, so the order you see is the order you left it. Every change is saved locally as you make it, so reloads and closed tabs cost you nothing. The surprise is the word 'locally': the list is tied to one browser on one device. Open the same page in another browser or on another computer and you start with an empty list; there is no account and no sync.
Worked example
A concrete input and expected output from the current implementation.
Input
Add these tasks: 'Renew car insurance' - priority High, due 2026-08-18, category Personal. 'Draft quarterly report' - priority High, due 2026-08-21, category Work. 'Call dentist' - priority Low, no due date, category Personal.

Expected output
The list shows three rows in the order they were added: 'Renew car insurance' with High priority, due 2026-08-18, category Personal; 'Draft quarterly report' with High priority, due 2026-08-21, category Work; and 'Call dentist' with Low priority and no due date. Reloading the page restores the same three rows because the list is saved locally.
The output echoes the input: each entry's title, priority, due date, and category are stored and rendered as a row, and the app never reorders tasks on its own, so the rows match the order they were entered. The persistence after reload follows from the local saving the tool's description promises.
