These Terms of Use (“Terms”) apply to your use of https://www.zerdly.com and its calculators, converters and browser tools (the “Service”), operated by Zerdly (a registered business name). By using Zerdly, you agree to these Terms. If you do not agree, please do not use the Service.
1. The Service
Zerdly provides free, browser-based calculators, converters and tools. Most tools run entirely in your browser. There are no accounts, and you can use the Service without registering. We may add, change or remove tools and features at any time.
2. No professional advice
Zerdly’s tools are provided for general information and as calculation, education and checking aids only. They are not a substitute for professional judgement or advice. You are responsible for verifying any result before relying on it. See our Disclaimer for important details, especially for engineering, surveying, electrical, financial, health, safety and construction calculations.
3. Provided “as is”
The Service is provided on an “as is” and “as available” basis, without warranties of any kind, whether express or implied, including as to accuracy, reliability, fitness for a particular purpose or uninterrupted availability. While we aim for correct and useful tools, we do not guarantee that results are error-free or suitable for your particular use.
4. Acceptable use
You agree not to:
- use the Service in any unlawful way or in breach of these Terms;
- attempt to disrupt, overload, attack or gain unauthorised access to the Service or its infrastructure;
- scrape, copy or systematically extract the site, its data or its source for republication or to build a competing dataset;
- misrepresent the Service or remove, obscure or alter any notices, branding or attributions.
5. Intellectual property
The Zerdly name, logo, design, content and the compilation of tools are owned by or licensed to the operator and are protected by intellectual property laws. You may use the Service for your own personal or business calculations. You may not copy, reproduce, redistribute or commercially exploit the site, its content or its underlying code without permission.
6. Third-party services and links
Zerdly relies on third-party providers (such as hosting and analytics) and may link to third-party websites. We are not responsible for the content, policies or availability of third-party sites. Your use of third-party services is subject to their own terms.
7. Limitation of liability
To the maximum extent permitted by law, the operator is not liable for any loss or damage (including indirect, incidental or consequential loss, loss of profits, or loss arising from decisions made using a tool) arising out of or in connection with your use of, or inability to use, the Service or any result it produces. Nothing in these Terms excludes any rights or guarantees you have under the Australian Consumer Law or other laws that cannot lawfully be excluded.
8. Privacy
Your use of the Service is also governed by our Privacy Policy, which explains how we handle information.
9. Changes to these Terms
We may update these Terms from time to time. The latest version is always available on this page with a last-updated date. Continuing to use the Service after changes means you accept the updated Terms.
10. Governing law
These Terms are governed by the laws of Australia. Courts of Australia will have jurisdiction over any dispute, without affecting any mandatory consumer-protection rights you have where you live.
