2. Calculator Results and Accuracy
2.1 For Informational Purposes Only
The calculators on this Site are provided for general informational and educational purposes only. Results should not be relied upon as professional financial, medical, legal, engineering, or other specialized advice.
2.2 No Guarantee of Accuracy
While we strive to provide accurate calculations, we make no warranty or guarantee that calculator results are accurate, complete, or current. Calculations may contain errors due to rounding, formula simplification, or other factors. Always verify important calculations independently and consult qualified professionals for decisions involving financial, medical, or safety matters.
2.3 Not Professional Advice
Nothing on the Site constitutes professional advice. For example, financial calculators do not constitute financial advice, health calculators do not constitute medical advice, and construction calculators do not constitute engineering advice. Always consult qualified professionals for important decisions.
3. Intellectual Property
3.1 Our Content
The Site and its original content, features, and functionality (including but not limited to text, graphics, logos, icons, images, calculator designs, and software code) are owned by ThePrimeCalculator and are protected by copyright, trademark, and other intellectual property laws.
3.2 Limited License
We grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Site for personal, non-commercial purposes. This license does not include the right to modify, reproduce, distribute, or create derivative works based on the Site or its content without our prior written consent.
3.3 Embedding
We may provide embeddable calculator widgets. If made available, you may embed our calculators on your website provided you maintain proper attribution and do not modify the embedded content. We reserve the right to revoke embedding permissions at any time.
4. User Accounts
The Site offers optional sign-in via Google. If you choose to sign in, you are responsible for maintaining the security of your Google account. We are not liable for any loss or damage arising from unauthorized use of your account.
We reserve the right to terminate or suspend access to accounts that violate these Terms or engage in abusive behavior.
5. Privacy
Your use of the Site is also governed by our Privacy Policy, which describes how we collect, use, and protect your information. By using the Site, you consent to the practices described in the Privacy Policy.
6. Disclaimer of Warranties
The Site is provided on an "as is" and "as available" basis, without any warranties of any kind, either express or implied.
To the fullest extent permitted by applicable law, we disclaim all warranties, including but not limited to implied warranties of merchantability, fitness for a particular purpose, non-infringement, and accuracy. We do not warrant that the Site will be uninterrupted, error-free, secure, or free of viruses or other harmful components.
7. Limitation of Liability
To the maximum extent permitted by applicable law, in no event shall ThePrimeCalculator, its owners, operators, employees, or affiliates be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or use, arising out of or related to your use of the Site.
This limitation applies whether the alleged liability is based on contract, tort, negligence, strict liability, or any other basis, even if we have been advised of the possibility of such damages. Because some jurisdictions do not allow the exclusion or limitation of liability for certain damages, in such jurisdictions, our liability shall be limited to the maximum extent permitted by law.
8. Indemnification
You agree to indemnify, defend, and hold harmless ThePrimeCalculator, its owners, operators, and affiliates from and against any claims, liabilities, damages, losses, costs, or expenses (including reasonable attorneys' fees) arising out of or related to your use of the Site, your violation of these Terms, or your violation of any rights of a third party.
9. Third-Party Links
The Site may contain links to third-party websites or services that are not owned or controlled by ThePrimeCalculator. We are not responsible for the content, privacy policies, or practices of any third-party websites. You access third-party sites at your own risk and should review their terms and privacy policies.
10. Modifications to the Site and Terms
10.1 Site Changes
We reserve the right to modify, suspend, or discontinue the Site (or any part of it) at any time without notice. We shall not be liable to you or any third party for any modification, suspension, or discontinuation of the Site.
10.2 Terms Changes
We may revise these Terms at any time by updating this page. The "Last updated" date at the top indicates when the Terms were last modified. Your continued use of the Site after any changes constitutes your acceptance of the revised Terms.
