Field notes
The project grid exposes fields for task, duration, dates, predecessor, completion percentage, colour, and notes. The file manager supports folders and recent projects, while the help explains importing by drag-and-drop and automatic saving. The site says project contents remain on the user's device; its privacy text separately describes anonymous visit statistics, including country, browser/device type, and referring site.
