Strength Calculator provides free online calculators and tools related to powerlifting and strength training, including but not limited to Wilks, DOTS, plate loading, powerlifting totals, estimated one-rep maxes, training maxes, and strength standards.

All tools, pages, and results are provided for informational and educational purposes only. They are designed to help users estimate, compare, and plan training data, not to provide certified scoring, personalized programming, or medical judgment.

You agree to use the site only for lawful purposes and in a manner that does not infringe the rights of others or disrupt the service.

• You must not use the site in violation of applicable local, national, or international laws.
• You must not attempt to gain unauthorized access to any part of the site, its systems, or related infrastructure.

All content on the site, including text, copy, branding, design elements, graphics, page layouts, and software code, is owned by or licensed to Strength Calculator and protected by applicable intellectual property laws.

We grant you a limited, non-exclusive, non-transferable license to access and use the site for personal, educational, and general coaching-reference purposes. This license does not allow you to reproduce, distribute, sell, publicly display, or commercially exploit site content without prior written permission.

Calculator results generated from your own inputs may be used freely for personal reference. That permission does not extend to republishing our site content, branding, interface design, or implementation as your own service.

Strength Calculator may display advertisements served by Google AdSense and other third-party advertising providers. By using the site, you acknowledge that advertising may appear on pages, tools, or supporting content.

• We reserve the right to place or remove advertisements on any page of the site at our discretion.
• Third-party advertisers may use cookies, web beacons, or similar technologies to measure ad performance or support ad targeting.
• We are not responsible for the content, claims, offers, or availability of third-party advertisements.
• Clicking on advertisements is voluntary and does not mean we endorse the advertised product or service.
• You agree not to engage in fraudulent clicking, automated clicking, incentivized clicks, or any activity intended to artificially inflate ad metrics.

For more information about how advertising cookies work, see our Privacy Policy.

The site may contain links to third-party websites, products, services, or resources that are not owned or controlled by Strength Calculator.

We have no control over and assume no responsibility for the content, terms, privacy practices, availability, or business conduct of any third-party website or service. Your use of third-party sites is at your own risk, and you should review their terms and privacy policies before using them.

Our calculators process the information you enter, such as body weight, lift numbers, and totals, locally in your browser. Unless a future feature clearly states otherwise, that calculator input is not stored on our servers.

You represent that the information you enter is accurate to the best of your knowledge and that you accept responsibility for how you use any output generated from your inputs.

We reserve the right to modify, suspend, or discontinue any part of the site at any time, with or without notice.

• We may update, remove, or replace calculator tools, formulas, features, designs, and supporting content.
• We may change these Terms of Service at any time by posting an updated version on this page.
• We may revise site structure, advertising placement, or legal disclosures as operational needs change.

We will reflect changes by updating the "Last updated" date at the top of the page. Your continued use of the site after changes become effective constitutes acceptance of the revised Terms.

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

Any dispute arising from these Terms or your use of the site should first be addressed through good-faith communication. If a dispute cannot be resolved informally, it may be submitted to a court or authority with competent jurisdiction in the applicable territory.

You agree to defend, indemnify, and hold harmless Strength Calculator and its owners from and against claims, damages, liabilities, losses, costs, and expenses arising out of or related to:

• Your use of or access to the site.
