Terms of Service

Last updated: May 1, 2026

1. Acceptance of Terms

By accessing or using DoesItAddUp.com ("the Site"), you agree to be bound by these Terms of Service. If you do not agree, please do not use the Site.

2. Description of Service

DoesItAddUp.com provides free, browser-based calculators for informational and educational purposes. All calculations are performed entirely within your web browser. No data you enter is transmitted to, processed by, or stored on any server operated by this Site.

3. Use of localStorage

The Site uses your browser's localStorage API solely to remember your chosen color theme across page visits. This data:

  • Never leaves your device
  • Is not accessible to any server or third party
  • Contains only a theme name (e.g., "midnight") — no personal information
  • Can be cleared at any time by clearing your browser's site data

We do not use tracking cookies, advertising cookies, analytics scripts, or any third-party data collection tools.

4. No Cookies

This Site does not set HTTP cookies of any kind. The localStorage notice shown on first visit is dismissed by writing a single flag ("diau-notice") to localStorage — this is not a cookie and is not transmitted to any server.

5. Disclaimer of Accuracy

All calculators are provided for informational purposes only. Results are estimates based on the inputs you provide and standard mathematical formulas. They do not constitute financial, legal, medical, or professional advice.

  • Mortgage calculator: Does not account for property taxes, insurance, PMI, HOA fees, or variable rate adjustments.
  • BMI calculator: BMI is a population-level screening metric and is not a clinical diagnostic tool. Consult a qualified healthcare provider for health assessments.
  • Salary calculator: Does not account for tax withholding, benefits, overtime rules, or jurisdiction-specific labor law.

Always verify important financial or health decisions with a qualified professional.

6. No Warranty

The Site is provided "as is" without warranty of any kind, express or implied. We do not warrant that the Site will be error-free, uninterrupted, or that results will be accurate for any specific purpose.

7. Limitation of Liability

To the fullest extent permitted by law, Does It Add Up? and its operators shall not be liable for any direct, indirect, incidental, special, or consequential damages arising from your use of or reliance on any calculation or content provided by this Site.

8. Intellectual Property

All original content, design, and code on this Site is owned by Does It Add Up? and its operators. You may not reproduce, distribute, or create derivative works without written permission, except for personal, non-commercial use.

9. Third-Party Links

This Site does not currently link to third-party services that collect your data. If that changes, this policy will be updated.

10. Changes to These Terms

We may update these Terms at any time. Continued use of the Site after changes constitutes acceptance of the updated Terms. The "last updated" date at the top of this page will reflect any changes.

11. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the United States, without regard to conflict of law principles.
