How it works
Clock in and Clock out read this device's clock when you select them. Worked time is the time between them minus breaks, counted in clock minutes.
Each shift counts in the week of the day it started. Weeks start on Sunday by default; you can switch to Monday.
One shift can last up to 24 hours. If a running shift goes past that, or the device clock moves back, the tracker asks you to discard it and add it by hand instead of guessing.
worked = clock out − clock in − breaks
week total = Σ worked time of the shifts that started that weekPrivacy. Shifts stay in this browser. Saving is off by default; when it is on, anyone who uses this browser can see the saved shifts.
Limitation. Times are clock minutes without daylight saving adjustments, so a shift that crosses a clock change can differ by one hour. Correct it by hand if needed.

Frequently asked questions
Are my shifts saved?
Only if you turn on “Save shifts on this device”. They stay in this browser, are removed 90 days after the last save, and you can clear them at any time.
What happens if I close the tab during a shift?
With saving on, the running shift is still there when you come back. With saving off, your browser warns you before the tab closes, because the shift would be lost.
Does it calculate pay or overtime?
No. It totals hours. To estimate overtime and gross pay, enter the hours in the Time Card Calculator.
Can I use it on more than one device?
No. There is no account and nothing is synced. Each browser keeps its own list; export a CSV file to move the hours.
