Step back through previous days one at a time. • Per-app daily time limits with a desktop notification when you cross one • 7-day history chart in preferences • Configurable data retention, plus a one-click purge • Time spent on the lock screen, while the screen is blanked, or while suspended is never counted Everything is stored locally in a plain JSON file. No network access, no telemetry.
