Last updated: September 12, 2026
1. Acceptance of terms
By accessing or using sahajtools.com (the "Site"), you agree to be bound by these Terms & Conditions. If you do not agree, please do not use the Site.
2. Description of the service
sahajTools provides free, browser-based statistics calculators and related educational content. The Site is provided for informational and educational purposes.
3. Permitted use
You may use the Site and its calculators for personal, educational, research, or professional reference purposes, subject to these Terms. You may not use the Site in any way that violates applicable law or infringes the rights of others.
4. Calculator results and estimates
Calculators on this Site compute results based on the formulas we implement and the inputs you provide. Results are estimates or calculations derived from those inputs, not guaranteed statistical, scientific, financial, medical, or other professional outcomes.
5. Accuracy and limitations
We make reasonable efforts to verify calculator formulas against authoritative sources before publishing them. However, we do not guarantee that every calculator is free of error at all times, that a calculator's underlying assumptions match your specific situation, or that results will be accurate, complete, or suitable for any particular purpose.
6. User responsibility
You are responsible for determining whether a given calculator, its inputs, and its underlying assumptions are appropriate for your intended use. You are responsible for the accuracy of the data you enter.
7. Reliance on results
Calculator outputs should not be treated as a substitute for professional statistical, academic, financial, medical, legal, or other expert advice, particularly for decisions with significant consequences. Where results materially affect an important decision, we recommend independent verification.
8. Intellectual property
The Site's design, branding, original text content, and underlying code are the property of sahajTools unless otherwise noted. You may not copy, reproduce, or redistribute substantial portions of the Site's content or code without permission, except as permitted through our embeddable calculator widgets under Section 9.
9. Website content and embedding
Where we provide an embeddable widget for a calculator, you may embed that widget on your own website using the embed code we provide, including its attribution link back to the original calculator page. You may not remove or obscure attribution in a way that misrepresents the calculator as your own original work. We do not guarantee that any specific link attribute (such as a followed link) will be preserved if you or your platform modifies the embed code.
10. Prohibited activities
You agree not to: interfere with or disrupt the Site's operation; attempt to gain unauthorized access to any part of the Site or its underlying systems; use automated means to scrape or reproduce the Site's content at scale without permission; or use the Site to distribute malware or engage in unlawful activity.
11. Third-party services and links
The Site may reference or link to third-party websites or services. We do not control and are not responsible for the content, accuracy, or practices of third-party sites.
12. Availability and service changes
We may modify, suspend, or discontinue any part of the Site, including individual calculators, at any time, with or without notice. We do not guarantee uninterrupted or error-free availability.
13. Errors and corrections
If we become aware of an error in a calculator's formula or logic, we will work to correct it. We are not liable for decisions made in reliance on a result later found to be affected by such an error, though we encourage users to report suspected errors to us.
14. Disclaimer of warranties
The Site and its calculators are provided "as is" and "as available," without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement.
15. Limitation of liability
To the fullest extent permitted by applicable law, sahajTools and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, profits, or opportunities, arising from your use of or inability to use the Site or its calculators.
