Terms of Use

Last updated: September 2026

By using Probably Useful, you agree to these Terms of Use. If you do not agree, please do not use the website.

General information and utilities

Probably Useful provides browser-based tools, calculators, guides, examples, and other general informational content. We aim to make them accurate and useful, but we do not guarantee that every result or piece of information will be complete, current, or suitable for your particular situation.

No professional advice

Content and tool results are not professional financial, accounting, tax, legal, medical, engineering, security, or other regulated advice. You are responsible for deciding whether a result is appropriate for your use and for obtaining professional advice when needed.

Your responsibility

You are responsible for the information you enter, how you interpret results, and any decisions or actions you take based on the website. Verify important calculations and information independently before relying on them for material decisions.

Acceptable use

You may use the website for lawful personal or business purposes. You may not intentionally interfere with the website, attempt unauthorized access, use automated systems in a way that unreasonably burdens the service, or use the site to violate applicable law or the rights of others.

Intellectual property

Unless otherwise indicated, the Probably Useful brand, site design, original written content, and custom tool implementations are owned by or licensed to the site operator. You may link to our pages and quote reasonable portions for commentary or reference, but you may not republish substantial portions of the website as your own service without permission.

Third-party links and services

The site may link to third-party websites, products, or services. We do not control those services and are not responsible for their availability, content, policies, or practices.

Availability and changes

We may change, update, suspend, or remove tools and content at any time. We do not guarantee uninterrupted access or that every feature will remain available.

Limitation of liability

To the maximum extent permitted by applicable law, Probably Useful and its operators will not be liable for indirect, incidental, consequential, special, or similar damages arising from your use of, or inability to use, the website. Nothing in these terms excludes liability that cannot legally be excluded.

Changes to these terms

We may update these Terms of Use from time to time. Continued use of the website after an updated version is posted means the new terms apply to your subsequent use.
