LOCAL FILES. REAL POSSIBILITIES.

Local time tracker

Start and stop work sessions, then transfer entries into timesheets or invoices.

Sessions stay in this tab. Download a JSON backup before leaving. Closing or reloading stops the active workflow; there is no background service or automatic storage.

No running session.

Billable minute rounding

Exact elapsed time is retained. Transfers use whole minutes, rounded once per session. Sessions crossing midnight split into local calendar days. Transfers use this browser’s current time zone. Sleep/background time is included; clock changes can affect elapsed time.

How privacy works

How it works

Name a task and hourly rate, start a work session and stop it when finished. Choose minute rounding and open the entries as a timesheet or invoice.

Supported formats

Active-tab work sessions; explicit JSON backups; in-memory transfers to timesheet and invoice tools.

Good to know

No automatic saving, background service or account history. Up to 200 sessions, seven days each. Clock changes affect elapsed time. Transfers split local calendar days and round once per session.

Worked example

Before

A 90-second work session with nearest-minute rounding

After

Two billable minutes transferred to a timesheet

Exact milliseconds remain in the tracker backup; the existing timesheet uses integer minutes and currency-precise amounts.

Save your work log before leaving

Stop the timer before exporting a backup or transferring entries. Keep the source tab open until the new tab confirms receipt. Transfers do not put tasks, rates or names into URLs or browser storage.

Troubleshooting

Why does my short tracked session show zero billable minutes?

Nearest-minute rounding gives zero below thirty seconds. Exact elapsed time is retained; choose round up only when that matches your billing arrangement.

Common questions

Does the tracker keep running after I close the tab?

No active session is saved automatically. Keep the tab open, stop completed work and export a JSON backup before closing.

Can I use this without an internet connection?

Yes, after you prepare this tool from Offline help and the browser retains its assets. Installation is optional. All processing dependencies are bundled locally.
