Terms of Use

1.0 Acceptance of Terms

By accessing and using the Definitive Calc™ website and calculators ("the Service"), you accept and agree to be bound by these Terms of Use. If you do not agree, do not use the Service.

These Terms of Use form a binding agreement between you and Definitive Calc LLC, a Colorado limited liability company ("Definitive Calc," "we," "our," or "us"). Elsewhere in this document, "Definitive Calc" means that LLC. Using the Service means you accept these terms.

2.0 Use License

Permission is granted to temporarily use Definitive Calc for personal and internal business transitory viewing and calculation purposes only. This is the grant of a license, not a transfer of title, and under this license you may not:

• Modify or copy the materials, calculators, or source code
• Use the materials for any commercial purpose or for any public display without authorization
• Remove any copyright or other proprietary notations from the materials
• Transfer the materials to another person or "mirror" the materials on any other server

This license shall automatically terminate if you violate any of these restrictions and may be terminated by Definitive Calc at any time.

3.0 Prohibited Use

You are expressly prohibited from engaging in the following activities:

3.1 Automated Access and Scraping

• Bots, Spiders, and Automated Scripts: You may not use bots, spiders, crawlers, scrapers, or any other automated means to access, collect, or extract data from Definitive Calc, including but not limited to calculator logic, formulas, results, or any other content.
• Data Extraction: You may not systematically retrieve data or content from our calculators or website for any purpose, including competitive analysis, data mining, or creating derivative works.
• API Access: You may not access our calculators through any automated interface or API that we have not explicitly provided or authorized.

• Reverse Engineering: You may not attempt to reverse-engineer, decompile, disassemble, or otherwise derive the source code, algorithms, or mathematical formulas underlying our calculators.
• Formula Extraction: You may not attempt to extract, copy, or replicate the mathematical formulas, calculation methods, or proprietary algorithms used in our calculators.
• Source Code Access: You may not attempt to access, view, or analyze our source code, JavaScript, or any other technical implementation details.

3.3 Site Performance and Security

• Disruption of Service: You may not engage in any activity that disrupts, interferes with, or degrades the performance of Definitive Calc, including but not limited to denial-of-service attacks, excessive requests, or resource-intensive operations.
• Security Bypass: You may not attempt to bypass, circumvent, or disable any security measures, authentication systems, or access controls implemented on our website.
• Unauthorized Access: You may not attempt to gain unauthorized access to any portion of the Service, other accounts, computer systems, or networks connected to the Service.
• Malicious Software: You may not introduce viruses, malware, or any other harmful code to the Service.

Violation of any of these prohibited uses may result in immediate termination of your access to the Service and may subject you to legal action.

4.0 Informational Use Only

5.0 Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY LAW, DEFINITIVE CALC SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS OR REVENUES, WHETHER INCURRED DIRECTLY OR INDIRECTLY, OR ANY LOSS OF DATA, USE, GOODWILL, OR OTHER INTANGIBLE LOSSES, RESULTING FROM:

In no event shall Definitive Calc's total liability to you for all damages exceed the amount of fifty dollars ($50.00) or the amount you paid to Definitive Calc in the past twelve months, whichever is greater.

6.0 Indemnification

You agree to defend, indemnify, and hold harmless Definitive Calc, its officers, directors, employees, agents, and affiliates from and against any and all claims, damages, obligations, losses, liabilities, costs, or debt, and expenses (including but not limited to attorney's fees) arising from:

• Your use of and access to the Service

• Your violation of any third-party right, including without limitation any copyright, property, or privacy right
• Any claim that your use of the Service caused damage to a third party

This defense and indemnification obligation will survive these Terms of Use and your use of the Service.

7.0 "As-Is" Service and Disclaimer of Warranties

THE SERVICE IS PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED.

Definitive Calc makes no warranties, expressed or implied, and hereby disclaims and negates all other warranties including, without limitation:

• Implied warranties or conditions of merchantability
• Fitness for a particular purpose
• Non-infringement of intellectual property or other violation of rights
• Accuracy, completeness, or reliability of calculator results
• Uninterrupted or error-free operation of the Service
• Security of data transmission or storage

Some jurisdictions do not allow the exclusion of implied warranties, so the above exclusion may not apply to you.

8.0 Advertising and Third-Party Services

Advertising: Definitive Calc does not currently display advertisements on the website and does not use third-party advertising networks to serve ads.

Analytics and other services: We may use third-party services that help us operate and understand use of the Service (for example, website analytics). Those providers may collect certain technical or usage information as described in our Privacy Policy.

GDPR Rights (EEA/UK Residents): If you are located in the European Economic Area (EEA) or United Kingdom, you have specific rights under the General Data Protection Regulation (GDPR) regarding the collection and use of your personal data. These rights are detailed in our Privacy Policy.

Definitive Calc is not responsible for the privacy practices or content of third-party websites or services that are linked from, or used in connection with, the Service. We encourage you to review the privacy policies of those third parties.

9.0 Optional Support

Using the Service does not require payment. If you choose to send optional support through the Support Definitive Calc™ page or the optional support section on a calculator page, payments go to Definitive Calc LLC.

Optional payments are voluntary support for the site—not a charitable donation, not a purchase of services, and not a tax-deductible gift. Definitive Calc does not issue receipts. A Zelle confirmation in your banking app is from your bank, not from us. We do not require a minimum amount. Support by Zelle® is final; we do not offer refunds.

Support is sent via Zelle® through your bank or credit union and the Zelle Network®, not through a payment form on this website. Information practices for optional support are described in our Privacy Policy.

10.0 Accuracy of Materials

The materials appearing on Definitive Calc could include technical, typographical, or calculation errors. While we strive for mathematical accuracy, Definitive Calc does not warrant that any of the materials on its website are accurate, complete, or current.

Definitive Calc may make changes to the materials, calculators, or content contained on its website at any time without notice. However, we do not make any commitment to update the materials.

11.0 Links to Third-Party Websites

Definitive Calc has not reviewed all of the sites linked to its website and is not responsible for the contents of any such linked site. The inclusion of any link does not imply endorsement by Definitive Calc of the site.

Use of any such linked website is at the user's own risk. We encourage you to review the terms of use and privacy policies of any third-party websites you visit.

12.0 Modifications to Terms

Definitive Calc may revise these Terms of Use for its website at any time without notice. By using this website, you are agreeing to be bound by the then-current version of these Terms of Use.

We will update the "Last updated" date at the top of this page when changes are made. Your continued use of the Service after any changes constitutes your acceptance of the new Terms of Use.

13.0 Governing Law

These Terms of Use are governed by the laws of the State of Colorado, without applying conflict-of-law rules that would point elsewhere. Any dispute arising out of or relating to these terms or the Service will be heard exclusively in the state or federal courts located in Colorado, and you consent to that venue and personal jurisdiction.

14.0 Contact and Legal Matters

Privacy requests (including access, correction, or deletion requests described in our Privacy Policy) should also be submitted through the Contact Us page so we can verify and document the request.
