ActivityWatch/activitywatch — reverse-engineered prompt

Build me a privacy focused time tracker that runs on Windows, Mac, and Linux. I want it to quietly record what I’m doing on my computer so I can understand where my time went, without sending my data to someone else’s server.

It should track the active app, window title, browser tab title and URL when possible, and keyboard or mouse activity so it can tell when I’m away. Store everything locally by default. Give me a clean dashboard where I can pick a day or date range, see a timeline, view totals by app or website, and spot idle time. I should be able to pause tracking, delete data, and export my own data.

Please make it feel easy for a normal person to install and use, not just developers. Keep the design simple and readable. Leave room for extra trackers later, like small add ons. Look up current docs online if you need to.
