The calculator itself

The wattage calculator on this site runs entirely in your web browser. The appliances you select, any custom appliances you add, and the results shown are never sent to, uploaded to, or stored on any WattReady server — they exist only in your browser's memory for that visit.

Information we may collect

Like most websites, WattReady's hosting and analytics providers may automatically log standard technical information when you visit — such as your IP address, browser type, device type, pages viewed, and referring site. We use this only in aggregate to understand how the site is used and to keep it running reliably.

Cookies and advertising

WattReady may display ads served through Google AdSense. Google and its partners may use cookies or similar technologies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising by visiting Google Ads Settings, and you can review how Google uses data from sites that use its services on Google's partner sites page.

Where visitors are in a region whose law requires it — the European Economic Area, the United Kingdom and Switzerland — a consent message is shown before any non-essential advertising cookie is set, and ads are served without personalisation unless consent is given. You can change or withdraw that choice at any time through the same message.

We do not set advertising cookies of our own, we do not operate a first-party ad server, and we do not sell or share personal information with data brokers.

Third-party links

This site may link to third-party retailers or brand websites (see our affiliate disclosure). We aren't responsible for the privacy practices of those sites — review their own policies before sharing information with them.

Your choices

You can disable cookies in your browser settings, use browser tools to block ad tracking, and clear any locally-stored data at any time. Because the calculator doesn't send your selections anywhere, there's nothing to delete on our end.
