How it works

Accepts clock in and clock out times (including overnight shifts) or a plain hours column, with break minutes deducted.
Configurable rules: weekly threshold (40h by default), daily overtime after 8h and double time after 12h.
Flags overlapping shifts, days over 16 hours, negative hours and long shifts with no break recorded.
Builds a per employee, per week summary of regular, overtime and double time hours.
Export the audit CSV for payroll review. Everything is computed locally on your device.
