Trako stores aggregate active-time totals locally on your Mac.
Trako does not collect, transmit, sell, or share personal data. Trako does not record which apps, windows, websites, documents, keystrokes, screenshots, or screen contents you use.
Trako stores daily totals and hourly totals in local app storage so the app can show your usage charts. If you enable Launch at Login, macOS stores that preference using Apple's login item system.
You can pause tracking at any time from the menu bar. Trako can also pause when the screen is locked, after a period without keyboard or mouse input, or when the Mac sleeps. You can reset today's tracked time from the menu bar or dashboard. To remove all stored history and projects, use Settings → Privacy → Delete all local data.
