The short version: we don't ask for personally identifying information, we don't use third-party tracking, and we don't sell anything you give us. Full details below.
When you submit the solar ROI calculator, the following data points are transmitted to our server:
These inputs are processed in memory, used to generate the response you see on screen, and then discarded. They are not written to any database, log file, or third-party service.
Like virtually all web servers, ours records the following information about each HTTP request, regardless of which page is visited:
These logs are retained for a maximum of 30 days and are accessible only to the operator of this site. They are not correlated with any other dataset and not shared with third parties. The single exception is law-enforcement requests served on us with valid legal process — in which case we will comply with the narrowest reading of the request.
This site does not set any cookies of its own. We do not use Google Analytics, Facebook Pixel, or any equivalent third-party analytics service.
If we add Google AdSense in the future (we are not currently running ads), AdSense and its advertising partners may set cookies to personalise advertisements, measure ad performance, and prevent fraud. We will update this page and display a consent notice prior to enabling AdSense. Google's use of advertising cookies is governed by Google's Advertising Policies. You can opt out of personalised advertising at Google Ads Settings or via the industry opt-out tools at aboutads.info and youronlinechoices.com.
Our contact form collects an email address (so we can reply) and the message body you submit. These are emailed to our editorial inbox and retained for as long as needed to handle the inquiry, then deleted within 90 days unless the conversation is ongoing.
Under the California Consumer Privacy Act (CCPA / CPRA) and the EU General Data Protection Regulation (GDPR), residents of those jurisdictions have rights including access, deletion, correction, and the right to opt out of data sale. Because we do not store personal information beyond rolling 30-day server logs, most of these rights are satisfied by default. If you have a specific concern, please contact us via the contact form and we will respond within the statutory window (45 days for CCPA, 30 days for GDPR).
This site is not directed at children under 13 and we do not knowingly collect data from them. If you believe a child has submitted information through our calculator or contact form, please contact us so we can delete the record.
Material changes to this policy will be announced via a banner on every page for at least 30 days following the change. The "last updated" date at the top of this page reflects the most recent revision.
Four inputs. Sixty seconds. Every number traceable to a public source.
