These terms apply to your use of lztoolbox.com, operated by Pasindu Senavirathna (see the Legal Notice). By using the site you agree to them. If you do not agree, please do not use the site.

1. Use of the tools

All tools are provided free of charge for personal, educational and commercial use. You may not attempt to disrupt the site, overload it with automated requests, scrape it at scale, or use it for unlawful purposes.

2. No warranty

The tools and information on this site are provided “as is” and “as available”, without warranties of any kind, express or implied. We work hard to make every result accurate, but we cannot guarantee that results are free of errors or suitable for your particular situation.

3. Electrical calculations

Electrical calculators are intended for planning, education and estimation. They are not a substitute for professional advice. Electrical installations, especially those connected to mains voltage, must comply with local regulations and should be designed, installed or checked by a qualified electrician.

4. Health and safety

Some tools, including the dead pixel test and stuck pixel fixer, display bright or rapidly changing colors. If you are sensitive to flashing lights or have photosensitive epilepsy, do not use these features. Start audio tests at a low volume to protect your hearing and your equipment. Take breaks during click-speed and other repetitive games.

5. Limitation of liability

To the fullest extent permitted by law, we are not liable for any direct, indirect, incidental or consequential damages arising from the use of, or inability to use, this site or its tools. Nothing in these terms limits liability that cannot be limited by law, such as liability for intent or gross negligence, or your statutory rights as a consumer.

6. Intellectual property and trademarks

The design, text, illustrations and software of this site belong to Pasindu Senavirathna. Product and company names mentioned on the site are trademarks of their respective owners and are used only for identification and compatibility information.

7. Third-party content and ads

The site displays ads and links to other websites. We are not responsible for the content, products or practices of third-party sites or advertisers.

8. Governing law

These terms are governed by the laws of the Democratic Socialist Republic of Sri Lanka, and the courts of Sri Lanka have jurisdiction over any dispute. If you use the site as a consumer, you keep any protections that the mandatory laws of your own country give you.

9. Changes

We may update these terms at any time. Continued use of the site after changes means you accept the updated terms.
