New: Usage analytics — on your device, opt-in only
- See where your time actually goes. A new Usage page shows a per-app time breakdown by day, with the FocusLock twist: every sample is tagged in-focus or out-of-focus at capture time, so you can see whether your top apps live inside your sessions or outside them.
- Off by default. Wiped on disable. Nothing is recorded until you turn it on from Settings. Turning it off atomically stops sampling and deletes every stored sample — no soft delete, no archive. The data lives in a local SQLite file on your Mac or PC and never touches a network. Not FocusLock's servers, not any cloud, not the family-controls server.
- Trust badge updated. "No Usage Tracking" was accurate before this release; now that opt-in analytics exist, the badge reads "Your Data Stays On-Device" — a more precise promise for what actually happens.
