Privacy Policy

Last updated: 2026

RF Toolbox (rftoolbox.ca) provides free online RF and microwave engineering calculators. This page explains what information is collected when you use the site and how it is used.

Calculators run in your browser

All calculators and simulators execute entirely client-side in your browser. The values you type into a calculator are processed locally and are not transmitted to, or stored on, our servers. We do not require accounts and do not ask for personal information to use the tools.

Cookies

This site uses cookies and similar technologies for two purposes: measuring traffic (analytics) and serving advertising. Cookies are small text files stored by your browser. You can block or delete cookies through your browser settings; the calculators will continue to work without them.

Advertising — Google AdSense

This site displays ads served by Google AdSense. In connection with serving ads:

• Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website and other websites.
• Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.
• You may opt out of personalised advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors' use of cookies for personalised advertising at aboutads.info/choices or youradchoices.com.
• For more detail, see How Google uses information from sites or apps that use its services.

Analytics — Google Analytics

This site uses Google Analytics to understand how visitors use the tools (for example, which pages are viewed, approximate location, and device/browser type). Google Analytics sets cookies and processes your IP address. You can opt out across all sites by installing the Google Analytics Opt-out Browser Add-on.

Consent (EU, UK, EEA, and Switzerland)

If you are located in the European Economic Area, the United Kingdom, or Switzerland, advertising and analytics cookies are used in accordance with applicable consent requirements. Where required, you will be asked for consent before non-essential cookies are set, and you can withdraw consent at any time through your browser settings.

Your choices

• Manage or block cookies in your browser settings.
• Opt out of personalised ads using the links above.
• Install the Google Analytics opt-out add-on.
