Privacy Policy

Last updated: August 26, 2026

This policy explains what information WattWise collects and how it's used.

Calculator data

The numbers you enter into any calculator on this site — distances, wattages, prices, rates — are processed entirely in your browser using JavaScript. They are not transmitted to a server, stored, or logged anywhere. Closing or refreshing the page clears them completely.

Cookies and advertising

This site may display advertising served by Google AdSense and its advertising partners. Google and its partners may use cookies and similar technologies to serve ads based on your prior visits to this site and others, and to measure ad performance.

You can learn more about how Google uses this data at policies.google.com/technologies/partner-sites, and manage your ad personalization settings at adssettings.google.com.

Analytics

This site may use analytics tools (such as Google Analytics) to understand aggregate traffic patterns — for example, which calculators are used most and which pages need improvement. Analytics data is aggregated and is not used to identify individual visitors.

Children's privacy

This site is not directed at children under 13, and does not knowingly collect personal information from children.

Your choices

You can block or clear cookies at any time through your browser settings, and opt out of personalized advertising through the Google Ads Settings link above or via the Digital Advertising Alliance at optout.aboutads.info.

Changes to this policy

This policy may be updated occasionally to reflect changes in the tools or services this site uses. The "last updated" date at the top reflects the most recent revision.
