Privacy

The short version: no accounts, no cookies, and what you type into the calculator stays in your browser.

The calculator

• Your appliances and settings are worked out in your browser. They are not sent to us.
• "Copy link to this plan" puts your plan in the page address so you can save or share it. Only people you give the link to can see it.
• When you choose a town or share your location, your browser asks NASA POWER for the sunshine at those coordinates. NASA receives the coordinates, as with any request to its service. We don't receive or store them.
• Sunshine results are kept in your browser for the current session so we don't ask NASA twice.

Hosting

Like any website, our hosting provider processes basic request data (such as IP address and browser type) to deliver pages and protect against abuse.

Changes

If we add analytics or advertising, we will update this page first and ask for consent where the law requires it.
