WINBIGFOX/TimeScribe ? reverse-engineered prompt

Build me a private time tracking app for macOS and Windows that works completely offline, with no account, no cloud sync, and no paywall.

I want a clean desktop app where I can start, pause, and stop tracking with one click, then see my day and week at a glance. It should let me track projects with notes, hourly rates, and billing totals, and also keep track of absences like vacation, sick days, and holidays. It would be great if it can show app usage and help me separate work from distractions, plus support automatic start and pause when I am idle or active.

Please include export options like PDF, Excel, and CSV, support multiple languages, keyboard shortcuts, and auto updates. Make it feel modern and easy to use, with all data stored locally on the device. If you need to look up any current desktop app or build docs online, go ahead and do that.
