Last updated: 26 April 2026

This Privacy Policy explains how SolarCalculatorHQ ("we", "us", "the site") collects, uses, and discloses information when you visit solarcalculatorhq.com. By using the site you agree to the practices described below. If you do not agree, please do not use the site.

Information we collect

The site collects two categories of information.

1. Information you actively provide

We do not require accounts or signups. The only personal data you actively provide is what you choose to send via email or our contact form (your email address and the contents of your message). We use this only to reply.

2. Information collected automatically

When you visit the site, our hosting provider and analytics tools automatically log:

• IP address (typically truncated for privacy)
• Browser type and version
• Operating system
• Pages visited, time on page, referring URL
• Approximate geographic location (country/region only)

Calculator inputs (such as latitude or wire length you enter into a calculator) are processed entirely in your browser. They are not sent to our servers.

Cookies and similar technologies

The site uses cookies and similar technologies (web beacons, local storage) for the following purposes:

• Essential: required for the site to function (e.g. remembering whether you've dismissed a notice)
• Analytics: to understand how visitors use the site so we can improve it
• Advertising: third-party advertising partners (see below) may set cookies to serve relevant ads and measure their effectiveness

Most browsers let you control cookies via their settings. Blocking or deleting cookies may affect your experience.

Advertising — Google AdSense and other partners

The site is supported by display advertising. We use Google AdSense and may use other ad networks. These third parties may use cookies, web beacons, or similar technologies to:

• Serve ads based on your prior visits to this site or other sites on the internet
• Measure ad performance and prevent fraud

Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and other sites on the internet. You can opt out of personalised advertising by visiting Google Ads Settings. You can opt out of third-party vendor use of cookies for personalised ads via aboutads.info.

For more information on Google's data practices, see the Google policies for partner sites.

Analytics

We may use Google Analytics 4 to understand site traffic and usage. Google Analytics processes IP addresses and aggregated event data. We do not use Google Analytics features that link analytics to advertising profiles (Google Signals, advertising features) without your consent where required. You can opt out via the Google Analytics opt-out browser add-on.

How we use information

• To operate, maintain, and improve the site
• To respond to your inquiries
• To detect and prevent abuse, fraud, and security incidents

Sharing of information

We do not sell your personal information. We share information with:

• Service providers who run the site infrastructure (hosting, CDN, analytics, advertising) under contractual confidentiality obligations
• Authorities when required by law, court order, or to protect rights and safety

Data retention

Server logs are retained for up to 30 days. Analytics data is retained for up to 26 months. Email correspondence is retained as long as needed to respond and for reasonable record-keeping.
