Solargrin's calculators run entirely in your browser. When you enter a number into a field on this site, that number is used to run a calculation on your device — it is not sent to, stored on, or processed by our servers. We don't require an account, an email address, or any personal information to use any calculator on this site.
Like most websites, our hosting provider automatically logs standard technical information for every visit — your IP address, browser type, device type, pages viewed and referring URL — for security and basic traffic measurement. We may also use privacy-respecting analytics to understand which tools are most useful, in aggregate, without identifying you individually.
Solargrin displays advertising served by Google AdSense and its advertising partners. These third parties may use cookies, device identifiers, or similar technologies to serve ads based on your prior visits to this or other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this site and/or other sites on the internet.
You can opt out of personalized advertising by visiting Google's Ads Settings, or opt out of third-party vendor use of cookies for personalized advertising by visiting www.aboutads.info.
Some pages link to external resources (government incentive databases, standards bodies, or similar). We aren't responsible for the privacy practices of sites we link to — review their own policies before sharing information with them.
Solargrin is not directed at children under 13, and we do not knowingly collect personal information from children.
You can clear cookies at any time through your browser settings, use a browser's private/incognito mode, or install a browser extension to block third-party advertising cookies. Doing so won't affect your ability to use any calculator on this site — none of them require cookies to function.
We may update this policy as the site evolves. Material changes will be reflected in the "last updated" date above.
