By accessing or using iStopwatch (the "Site"), you agree to be bound by these Terms of Service. If you do not agree, please do not use the Site.
iStopwatch provides free, browser-based time-tracking tools, including a stopwatch, countdown timer, interval/Tabata timer, world clock and date calculator. The Site is provided for personal, non-commercial use.
You agree not to:
The Site does not require registration. Any preferences (such as saved world-clock cities) are stored locally in your browser and are not tied to an account.
The Site and its tools are provided "as is" and "as available," without warranties of any kind, express or implied. While we aim for high accuracy, timing tools rely on your device's system clock and browser performance, and we do not guarantee the Site will be error-free, uninterrupted, or suitable for time-critical or safety-critical purposes.
To the fullest extent permitted by law, iStopwatch and its operators shall not be liable for any indirect, incidental, or consequential damages arising from your use of, or inability to use, the Site.
The Site may display advertisements served by Google and other third-party ad networks. We do not control the content of these ads. Your interactions with any advertisement or third-party site are governed by that party's own terms and privacy policy. See our Privacy Policy for more information.
The design, layout, and code of the Site are the property of iStopwatch unless otherwise noted, and may not be copied or redistributed without permission.
We may update these Terms from time to time. Continued use of the Site after changes are posted constitutes acceptance of the revised Terms.
