No. Fragment runs in the background once installed and configured. There are no manual timers to start or stop. It watches your foreground window automatically.
Every app and website has a classification rule (productive, distracted, or neutral) that you can view and edit in Settings. You can also override specific time blocks, like marking one part of a YouTube session differently from the rest.
No. Fragment checks whether audio is actually playing before applying its idle timeout, so a silently-watched video won't get flagged as time away from your desk.
Locally, in a SQLite database on your own machine - nothing is uploaded anywhere.
Fragment targets Windows 10 and 11. macOS and Linux are not currently planned.
Not yet. It's currently a concept and early prototype. See the USB Hub project page for the current plan.
The exact behavior is still being designed, likely a reduced charge rate or a full pause on selected ports, based on rules you configure in Fragment. This will be documented in full once finalized.
Yes. A manual override is a planned feature, so the hub never leaves you stuck without power when you genuinely need it.
