The simple rules that apply when you use stopwatch-online.com. Please take a minute to read them.
Last updated: April 30, 2026
1. Acceptance of these terms
Welcome to stopwatch-online.com (the "Service", "Site", or "we"). These Terms of Use ("Terms") govern your access to and use of the website at https://stopwatch-online.com, including the stopwatch, timer, alarm clock, pomodoro timer, world clock, age calculator, holidays, and any other tool we publish on the same domain.
By accessing or using the Site, you agree to be bound by these Terms and by our Privacy Policy. If you do not agree, please do not use the Site.
2. About the Service
stopwatch-online.com is a free, browser-based collection of time-related utilities. Each tool runs in your browser using standard web technologies (HTML, CSS, JavaScript). You do not need an account to use any of the tools, and we do not charge for access.
Because the Service is free of charge, we reserve the right to modify, suspend, or discontinue any tool, page, or feature at any time and without prior notice. We will try to give reasonable advance notice for major changes, but we cannot guarantee it.
3. License to use the Service
Subject to your compliance with these Terms, we grant you a personal, worldwide, non-exclusive, non-transferable, revocable licence to access and use the Site for your own personal or internal business purposes. You may use the tools as often as you like, on as many devices as you own.
This licence does not give you any ownership of the Site or its underlying source code, branding, or content.
4. Acceptable use
When using the Service, you agree that you will not:
- Use the Service for any unlawful purpose, or in violation of any applicable law or regulation.
- Attempt to gain unauthorised access to the Site, our hosting infrastructure, or any other system.
- Probe, scan, or test the vulnerability of the Service or its network without our express written permission.
- Interfere with or disrupt the Service - for example by introducing malware, by performing denial-of-service attacks, or by sending automated traffic at a rate that degrades the experience for other visitors.
- Use automated scrapers, bots, or other tools to mass-extract content from the Site beyond what a normal browser would request.
- Repackage, mirror, or republish the Service as if it were your own.
- Remove, obscure, or alter any copyright, trademark, or other proprietary notices.
We reserve the right to block any IP address, user-agent, or other source of traffic that we reasonably believe is engaged in any of the above.
5. Intellectual property
All content on the Site - including the visual design, text, layout, branding, source code, illustrations, icons, and logos - is owned by or licensed to stopwatch-online.com and is protected by copyright, trademark, and other intellectual property laws.
You may share links to public pages on the Site freely. You may take screenshots for personal use, reviews, or news commentary. Beyond that, you may not copy, modify, distribute, sell, or lease any part of the Site without our prior written permission, except where doing so is permitted by applicable copyright law (e.g. fair use, fair dealing).
Third-party trademarks (such as "Pomodoro Technique", which is a registered trademark of Francesco Cirillo) belong to their respective owners and are referenced only for descriptive purposes.
6. Accuracy and "as-is" service
We work hard to keep our tools accurate and reliable. The stopwatch and timer use the browser's performance.now() high-resolution clock, which is sub-millisecond accurate on modern devices. The Holidays data, World Clock zones, and similar reference data are maintained on a best-effort basis from public sources.
However, the Service is provided "as is" and "as available", without any warranty of any kind, whether express, implied, or statutory. To the maximum extent permitted by law, we disclaim all warranties, including but not limited to:
- Warranties of merchantability or fitness for a particular purpose.
- Warranties that the Service will be uninterrupted, error-free, secure, or free of harmful components.
- Warranties about the accuracy, reliability, or timeliness of any data shown - including holiday dates, time-zone offsets, and the maximum precision of the timer.
You should not rely on the Site for any purpose where an inaccurate result could cause harm - for example, official sports timing, medical timing, legal deadlines, aviation, scientific instrumentation, or any other safety-critical use. For those use cases, please use a certified hardware device or a service that explicitly guarantees accuracy.
7. Limitation of liability
To the maximum extent permitted by applicable law, in no event shall stopwatch-online.com, its operators, contributors, or affiliates be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or goodwill - whether arising in contract, tort (including negligence), or otherwise - arising out of or in connection with your use of, or inability to use, the Service.
Where liability cannot be excluded by law, our total aggregate liability to you for all claims arising out of or relating to the Service shall be limited to the greater of (a) the amount you paid us to use the Service in the 12 months preceding the claim, or (b) ten US dollars (US$10). Because the Service is free, in most cases this means our liability is effectively capped at US$10.
Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain damages. In those jurisdictions, the disclaimers and limitations above apply only to the maximum extent permitted by law, and nothing in these Terms is intended to limit any rights you have that cannot be lawfully limited.
8. Indemnity
You agree to indemnify, defend, and hold harmless stopwatch-online.com and its operators from and against any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or in any way connected with your use of the Service in breach of these Terms or in violation of any applicable law.
9. Third-party links and services
The Site may contain links to third-party websites or services that are not owned or controlled by us - for example, articles on MDN Web Docs, Wikipedia, or other reference sources. We do not endorse, monitor, or take responsibility for any third-party content, privacy policies, or practices. Once you click an external link, the destination site's terms and privacy policy apply, not ours.
10. Privacy
Your use of the Service is also governed by our Privacy Policy, which explains what little data we have access to and how we handle it. By using the Service, you acknowledge that you have read and understood the Privacy Policy.
11. Changes to these Terms
We may update these Terms from time to time - for example, when we add a new tool, when applicable law changes, or when we improve the wording. The updated version will be posted on this page with a new "Last updated" date at the top.
If a change is significant, we will make a reasonable effort to draw attention to it. Your continued use of the Service after the new Terms take effect means you accept the updated Terms. If you do not agree, please stop using the Service.
12. Termination
Because there are no user accounts, you can stop using the Service at any time simply by closing the tab. We may suspend or terminate your access to the Service - in whole or in part, with or without notice - if we reasonably believe you are in breach of these Terms or if continued access would create a legal or security risk.
Sections that by their nature should survive termination (including Sections 5 - 8 and 13) will continue to apply after access ends.
13. Governing law and disputes
These Terms, and any dispute arising out of or in connection with them or with your use of the Service, will be governed by the laws of the jurisdiction in which the operator of stopwatch-online.com is based, without regard to its conflict-of-laws rules. Where mandatory consumer-protection laws of your country of residence give you stronger protections, those mandatory laws will continue to apply.
Before starting any formal legal proceeding, please contact us first - most disagreements can be sorted out by email.
14. Severability
If any provision of these Terms is found to be invalid, illegal, or unenforceable, the remaining provisions will continue in full force and effect. The invalid provision will be replaced by a valid provision that most closely matches the original intent.
