Terms of Use

1. Acceptance of Terms

These Terms of Use (“Terms”) govern your access to and use of NerdyTools.com (“the Site,” “we,” “us,” “our”), including all calculators, tools, content, and services provided on the Site. By using the Site, you acknowledge that you have read, understood, and agree to be bound by these Terms. We may update these Terms from time to time — continued use of the Site after changes constitutes acceptance.

2. Description of Service

NerdyTools.com provides free online calculators and tools for finance, health, mathematics, web development, and other categories. All tools are provided for general informational and educational purposes only. The Site does not require registration or login and is available to the general public at no charge.

3. Use of the Site

You may use NerdyTools.com and its tools for personal, educational, and professional purposes. When using the Site, you agree to:

• Use the tools and content for lawful purposes only.
• Not attempt to interfere with, disrupt, or compromise the integrity or security of the Site.
• Not use automated scripts, bots, or scraping tools to access the Site in a manner that burdens the server or degrades performance for other users.
• Not attempt to reverse-engineer, copy, or redistribute the Site’s source code, tools, or content without permission.

4. No Professional Advice

The calculators and tools on NerdyTools.com are for general informational and educational purposes only. They do not constitute professional financial, tax, legal, medical, health, or any other form of professional advice. Results are estimates based on standard formulas and the inputs you provide — they may not account for all variables relevant to your specific situation.

Always consult a qualified professional — such as a financial advisor, tax professional, doctor, or lawyer — before making important decisions based on calculator results. We are not responsible for decisions made based on information provided by our tools.

5. Accuracy and Limitations

We strive to make our calculators accurate by using established, peer-reviewed formulas and keeping data up to date. However, we do not guarantee that all results are error-free, complete, or current. Factors beyond our control — such as changes in tax laws, interest rates, medical guidelines, or exchange rates — may affect the accuracy of results.

Use our tools as a starting point for research and planning, not as a definitive source. If you discover an error in any calculator, please contact us so we can investigate and correct it.

6. Intellectual Property

All content on NerdyTools.com — including text, design, code, graphics, logos, and tool interfaces — is the property of NerdyTools.com or its content creators and is protected by applicable copyright and intellectual property laws. You may not reproduce, distribute, modify, or create derivative works from our content without prior written permission, except for personal, non-commercial use such as printing a calculator result for your own reference.

7. Privacy

Your privacy is important to us. Our calculators run in your browser and do not transmit your inputs to our servers. For details on what data we do and do not collect (including information about cookies and advertising), please refer to our Privacy Policy and Cookie Policy.
