Keep a copy you control

Hours are stored in this browser on this device. Download a backup before clearing browser data or moving to another device.

Imports add missing records, keep existing ones, and never overwrite your current hours. Original Studio Clock JSON files are supported.

Optional file saving

On supported browsers, connect a JSON file to save a snapshot whenever your data changes. Reconnect after reopening this page.

01  Start small

Pick a project, describe your task, and start. Stop when you take a break. Resume a past task from its entry.

02  Make it accurate

Forgot to start or stop? Add time manually or edit an entry. The timer includes time when your device sleeps; review long sessions.

03  Take your hours with you

Filter a period, then export a CSV for spreadsheets. Use a JSON backup to move your full history. No account or cloud sync required.

Review your import

Existing IDs will be kept. Imported running timers will become stopped entries ending at the import time. Review their duration afterwards.

Deleted entries

These entries are excluded from totals and CSV exports. Restore them at any time.
