Terms of Service
Effective Date: January 1, 2026 | Last Updated: September 26, 2026
1. Acceptance of Terms
Welcome to OnlineTimeZone (https://www.onlinetimezone.com). By accessing, browsing, or using any of our tools, calculators, clocks, or related services, you agree to be bound by these Terms of Service ("Terms") and our Privacy Policy.
If you do not agree with any part of these Terms, your sole remedy is to discontinue using the website immediately.
2. Description of Free Services
OnlineTimeZone provides free browser-based time utilities, including but not limited to online alarm clocks, countdown timers, stopwatches with split laps, world clocks, time zone converters, date calculators, age calculators, hours worked calculators, and educational classroom timers.
All tools are provided free of charge for personal, classroom, educational, and commercial convenience without requiring account sign-up.
3. Client-Side Execution & Practical User Requirements
Because OnlineTimeZone runs completely on the client side inside your web browser without a backend cloud connection:
- Active Browser Tab: Alarms and timers depend on an active or open browser tab. Closing the tab, quitting the browser, or allowing your operating system to put the browser process to sleep will halt or delay timer triggers.
- Device Power & Sleep Settings: An alarm cannot sound if your computer, laptop, or phone goes into deep sleep, hibernation, loses power, or has its volume muted.
- Audio Output: Ensure your device's speakers or headphones are turned on, unmuted, and properly connected before relying on an audible alarm alert.
4. Disclaimer of Warranties ("As Is" and "As Available")
OnlineTimeZone and all associated content, tools, calculations, and scripts are provided strictly on an "AS IS" and "AS AVAILABLE" basis without warranties of any kind, whether express or implied.
While we utilize standardized databases (including the official IANA Time Zone Database) and high-precision browser timestamps (requestAnimationFrame), we make no guarantee or warranty that:
- The service will be completely uninterrupted, timely, secure, or entirely error-free at all times.
- Calculations or time conversions will fulfill high-stakes legal, medical, regulatory, or financial compliance requirements without independent verification.
Important: Do not rely solely on an automated browser tool for life-critical wakeups, medical schedules, flight departures, or mandatory legal deadlines. Always maintain a secondary reliable physical alarm or independent verification.
5. Limitation of Liability
To the maximum extent permitted by applicable law, OnlineTimeZone, its developers, operators, and affiliates shall not be liable for any direct, indirect, incidental, special, consequential, or punitive damages resulting from your use of, or inability to use, our services. This includes, without limitation, missed appointments, delayed departures, loss of work time, or incorrect time calculations resulting from hardware power failure, sleep states, browser crashes, or clock drift.
6. Intellectual Property Rights
The site design, logos, graphics, visual layout, interactive user interfaces, and custom JavaScript code are the exclusive intellectual property of OnlineTimeZone and are protected by applicable copyright and trademark laws. You may not republish, mirror, redistribute, or reverse-engineer substantial portions of our site code without express written authorization.
7. Acceptable Use & Prohibited Conduct
When using OnlineTimeZone, you agree NOT to:
- Engage in automated attacks, Denial of Service (DoS/DDoS) actions, or script injections that disrupt server availability.
- Bypass, alter, or disable any security features, headers, or technical restrictions on the website.
- Embed or frame our tools on third-party domains in a deceptive manner without attribution.
8. Third-Party Advertisements & External Links
OnlineTimeZone displays third-party advertisements (such as Google AdSense) to keep all utilities completely free for the public.
We do not endorse, guarantee, or assume liability for products, services, claims, or external content provided by third-party advertisers or external websites linked from our pages. Any interactions or purchases with third parties are solely between you and the third party.
9. Modifications to These Terms
We reserve the right to revise or update these Terms of Service at any time. When updates occur, the "Last Updated" date at the top of this document will be modified. Your continued use of the website following any changes constitutes your binding acceptance of the updated terms.
