Acceptable use

You may use the public tools for lawful personal or business purposes.

Unless otherwise stated, the USFITools brand, original site text, layouts and custom code are protected by applicable intellectual-property laws. Third-party libraries, data and trademarks remain subject to their respective licences and owners.

Third-party services

Some features may rely on third-party data providers, libraries, hosting, analytics, advertising or affiliate services. We are not responsible for third-party outages, policy changes or external website content.
