Is my data saved when I close the browser?

Yes. All task and session data is stored in your browser's localStorage and will be there the next time you open the page on the same device and browser.

Can I run multiple timers at the same time?

No. Only one timer can run at a time. Starting a new timer automatically stops the currently running one, keeping your log accurate.

How do I export my time log?

Click the Export CSV button. The downloaded file contains columns for task name, start time, end time, and duration in minutes for every session.

Can I delete a task or session?

Yes. Each task has a delete button. Deleting a task removes all its recorded sessions. Individual sessions can also be removed from the task detail view.

このツールについて

Time Tracker is a lightweight, browser-based productivity tool for logging how you spend your day. Add named tasks, start a timer with one click, and stop it when you switch contexts. Each session is recorded with its start time, end time, and duration. The dashboard shows total time per task and a daily summary. All data is stored in localStorage so it persists between browser sessions without any account. Export your log as a CSV file for import into spreadsheets or invoicing tools.
