Privacy Policy
Last updated: August 2026
1. Introduction
Definitive Calc LLC, a Colorado limited liability company ("Definitive Calc," "we," "our," or "us"), operates the Definitive Calc™ website at https://definitivecalc.com and is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard information when you visit the site. By using the website, you consent to the practices described here.
2. Information We Collect
We may collect information about you in a variety of ways. The information we may collect includes:
- Personal Data: Personally identifiable information that you voluntarily provide through our Contact Us or Request a Calculator forms, including your name and email address. The Request a Calculator form may also include the calculator idea and related details you submit.
- Automatically Collected Data: Information our servers automatically collect when you access the website, such as your IP address, browser type, operating system, access times, pages viewed, and referring website addresses.
- Cookie Data: Data collected through cookies and similar tracking technologies to enhance your experience and analyze site usage.
- Usage Data: Information about how you interact with our calculators and website features.
3. How We Use Your Information
We may use information collected about you for various purposes, including:
- To provide, maintain, and improve our calculator services
- To respond to your inquiries, support requests, and calculator requests submitted through those forms
- To analyze how you use our website and services to enhance user experience
- To detect, prevent, and address technical issues and security threats
- To comply with legal obligations and enforce our terms of service
Legal Basis for Processing (GDPR): Our legal basis for processing your personal data is Legitimate Interest. We process your data to provide and improve our free calculator services, respond to user inquiries, and maintain website security and functionality.
4. Cookies and Tracking Technologies
We use cookies and similar tracking technologies (such as browser Local Storage) to track activity on our website and hold certain information. Specifically, we use Local Storage to save your cookie consent preferences so we don't have to ask you every time you visit. Cookies are files with a small amount of data which may include an anonymous unique identifier. You can instruct your browser to refuse all cookies or to indicate when a cookie is being sent.
Website analytics: We may use a third-party analytics service to help understand how visitors use the site. That service may use cookies or similar technologies to collect information such as how often users visit, which pages they view, and general referral information. You can limit or block cookies through your browser settings; declining non-essential cookies (where we offer that choice) also limits analytics collection where applicable. Analytics providers have their own privacy policies governing information they process.
5. Advertising
No third-party advertising: Definitive Calc does not currently display advertisements on the website and does not use third-party advertising networks to serve ads to visitors.
Because we do not run advertising on the site, we do not use advertising cookies or share your information with advertising networks for the purpose of serving personalized ads. If this practice changes in the future, we will update this Privacy Policy and the "Last updated" date before introducing advertising.
6. Data Security
We use administrative, technical, and physical security measures to help protect your personal information. Data submitted through our Contact Us and Request a Calculator forms is handled securely using industry-standard encryption and security protocols.
While we have taken reasonable steps to secure the personal information you provide to us, please be aware that despite our efforts, no security measures are perfect or impenetrable, and no method of data transmission can be guaranteed to be 100% secure.
7. Your Privacy Rights (GDPR - EEA/UK Residents)
If you are located in the European Economic Area (EEA) or United Kingdom, you have certain data protection rights under the General Data Protection Regulation (GDPR):

To exercise any of these rights, please contact us through our Contact Us page. We will respond to your request within one month.
8. California Consumer Privacy Rights (CPRA/CCPA)

- Right to Know: You have the right to know what personal information we collect, use, disclose, and sell.
- Right to Delete: You have the right to request deletion of your personal information.

To exercise your California privacy rights, please contact us through our Contact Us page. We will verify your identity before processing your request.
9. Children's Privacy (COPPA)
Definitive Calc is a general audience site and does not knowingly collect personally identifiable information from children under the age of 13. Our services are not directed to children, and we do not knowingly collect personal information from children under 13 years of age.
If you are a parent or guardian and believe that your child under the age of 13 has provided us with personal information, please contact us immediately through our Contact Us page. Upon receiving such a request, we will delete the child's personal information from our records immediately.
We encourage parents and guardians to monitor their children's online activities and to help enforce this Privacy Policy by instructing their children never to provide personal information through our website without their permission.
10. Third-Party Services
We may employ third-party companies and individuals to facilitate our service, provide service on our behalf, perform service-related services, or assist us in analyzing how our service is used. These third parties have access to your information only to perform these tasks on our behalf and are obligated not to disclose or use it for any other purpose.
Third-party services we use may include website analytics providers. Those providers have their own privacy policies governing information collected through their services.
Voluntary support: If you choose to support Definitive Calc™ through the Support Definitive Calc™ page or through the optional support section on a calculator page, optional payments go to Definitive Calc LLC. The same practices apply either way. Support is sent via Zelle®. The transfer is handled by your bank or credit union and the Zelle Network®—not by a payment form on this website. Definitive Calc does not collect your bank login or Zelle credentials. This website does not receive or store Zelle payment transactions.
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. Those terms are set out in our Terms of Use.
11. Data Retention
We retain your personal information only for as long as necessary to fulfill the purposes outlined in this Privacy Policy, unless a longer retention period is required or permitted by law. When you submit our Contact Us or Request a Calculator form, we retain your information only as long as necessary to respond to your inquiry, provide support, or evaluate and follow up on a calculator request.
Automatically collected data (such as IP addresses and usage statistics) may be retained for longer periods for security, analytics, and legal compliance purposes.
12. International Data Transfers
Your information may be transferred to and maintained on computers located outside of your state, province, country, or other governmental jurisdiction where data protection laws may differ. By using our website, you consent to the transfer of your information to facilities located in the United States and other countries where we operate.
13. Changes to This Privacy Policy
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date at the top of this policy.
You are advised to review this Privacy Policy periodically for any changes. Changes to this Privacy Policy are effective when they are posted on this page.
