Terms of Service

Last updated: June 12, 2026

These Terms of Service ("Terms") govern your use of the Craft Calc Lab website at craftcalclab.com(the "Site"). By accessing or using the Site, you agree to be bound by these Terms. If you do not agree to these Terms, do not use the Site.

1. Description of Service

Craft Calc Lab provides free online calculators and tools for crafting, making, and artisan work. Tools include calculators for soap making, woodworking, packaging design, brewing, and other crafts. All tools run client-side in your browser and are provided at no cost.

2. Acceptable Use

You agree not to:

  • Use the Site for any unlawful purpose or in violation of any applicable laws
  • Attempt to gain unauthorized access to any part of the Site or its systems
  • Interfere with or disrupt the Site's infrastructure, including through automated scraping at excessive rates, denial-of-service attacks, or injection of malicious code
  • Reproduce, duplicate, or resell any part of the Site without express written permission
  • Use the Site to distribute malware, spam, or other harmful content
  • Circumvent, disable, or otherwise interfere with security-related features of the Site

3. Intellectual Property

The Site's design, layout, text content, graphics, and code are owned by Craft Calc Lab and protected by applicable intellectual property laws. You may use the calculators for personal and commercial crafting purposes. You may not copy, modify, distribute, or create derivative works of the Site itself without permission.

The calculation results you generate using our tools are yours. We claim no ownership over outputs produced by your use of the calculators.

4. Disclaimer of Warranties

The Site and all tools are provided "as is" and "as available" without warranties of any kind, either express or implied. We do not warrant that:

  • The tools will be error-free or uninterrupted
  • Calculation results will be perfectly accurate for every material or scenario
  • The Site will meet your specific requirements

While we strive for scientific accuracy and cite our formula sources, real-world results depend on many variables including material quality, environmental conditions, and measurement precision. You are responsible for verifying results independently before making critical decisions based on them.

5. Limitation of Liability

To the maximum extent permitted by law, Craft Calc Lab shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising out of or related to your use of the Site. This includes, without limitation, damages for loss of materials, wasted supplies, or errors in crafting projects.

Our total liability for any claim arising from your use of the Site shall not exceed the amount you paid us (which is zero, since the service is free).

6. Third-Party Advertising

The Site displays advertisements provided by third-party advertising networks, including Google AdSense. These advertisements are not endorsements by Craft Calc Lab. We are not responsible for the content, accuracy, or practices of any third-party advertisers.

Third-party advertisers may use cookies and similar technologies to serve ads based on your browsing activity. For more information, see our Privacy Policy.

7. External Links

The Site may contain links to external websites. We are not responsible for the content, privacy practices, or availability of external sites. Inclusion of a link does not imply endorsement.

8. Modifications to the Service

We reserve the right to modify, suspend, or discontinue any part of the Site at any time without prior notice. We may add, remove, or update tools at our discretion. We shall not be liable to you or any third party for any modification, suspension, or discontinuation of the Site.

9. Changes to These Terms

We may revise these Terms at any time by posting the updated version on this page. The "Last updated" date at the top will reflect when changes were made. Your continued use of the Site after any changes constitutes acceptance of the new Terms.

10. Governing Law

These Terms shall be governed by and construed in accordance with applicable laws. Any disputes arising from your use of the Site shall be resolved through good-faith negotiation first, and failing that, through appropriate legal channels in the jurisdiction where the Site operator resides.

11. Severability

If any provision of these Terms is found to be unenforceable, the remaining provisions shall continue in full force and effect.
