Terms of use
Use the tools freely for personal or professional timing. There is no warranty and no account, and nothing here should be used for safety-critical timing.

Using this site
You may use these tools for personal and professional purposes at no cost. Please do not attempt to break, overload or scrape the service at scale, and do not misrepresent it as your own.
No warranty
The tools are provided as they are, without warranties of any kind. A browser-based stopwatch depends on your device clock and on your browser continuing to run. For medical, safety, legal or competition-critical timing, use certified hardware.
Accuracy and limitations
Timing is derived from your device clock with millisecond resolution and is intended for everyday use: sport practice, workouts, study, cooking, classroom activities and similar tasks.
Closing a tab or restarting a device ends a session, and settings stored in your browser can be lost if you clear site data.
Advertising and third-party services
The site displays third-party advertising and may use analytics, each subject to its own provider’s terms. Advertisements are labelled and are not part of the tools.
Changes
These terms and the tools themselves may change as the site evolves. If a change is significant, the update date on this page moves with it.
