Back to stopwatch About the app

Data we collect

Local timer data stored in your browser (start timestamp and total elapsed time).
Analytics data such as page views, approximate location, device type, and interaction events.

How we use data

To keep your stopwatch running across sessions.
To understand which features are used and improve the app.

Local storage

The stopwatch stores two values in localStorage on your device:

start_tmp: Timestamp in milliseconds when the timer is running.
accumulated_time: Total elapsed time in milliseconds.

These values never leave your browser unless you clear or sync your browser storage.

Analytics provider

We use Google Analytics 4 to collect usage statistics. Google may set cookies or similar identifiers to measure traffic and usage. Data is processed by Google LLC in accordance with their privacy policy.

Your choices

You can clear localStorage at any time to reset the stopwatch.
You can block analytics cookies in your browser settings or with privacy extensions.
