Privacy Policy

Last updated: 26 September 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.

Country selection for regional offers

Where a page has approved regional offers, we use the approximate country supplied by Vercel, our hosting provider, to suggest an offer country. The country-selection code uses only the country code: it does not read, store or forward your full IP address, and does not contact an external location lookup service. Normal hosting requests and security logs remain separate.

You can change the offer country if the suggestion is wrong or your project is elsewhere. This choice stays in the current page's memory; it is not saved in cookies or local storage. It does not change the calculator's assumptions or page language. Country detection is approximate and does not establish delivery or service eligibility.

We do not send calculator inputs with the country request or add country selections to our analytics. If you follow a partner link, the destination's own privacy and tracking practices apply.

Cookies and similar technologies

Country selection stays in the current page's memory and does not use cookies or local storage. The analytics section below describes whether analytics is enabled. External sites you choose to visit through an outbound link may set their own cookies or use similar tracking technologies.

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

Advertising and partner links

Some calculator results include eBay Partner Network links. As an eBay Partner, we may be compensated if you make a purchase. We disclose this relationship beside the link before you click.

These links include affiliate campaign and placement identifiers so eBay can attribute referrals and qualifying purchases. We do not add your calculator inputs, contact details or country selection to the link. When you follow it, eBay's privacy and tracking practices apply, including any cookies or similar technologies it uses for attribution. This site does not load eBay tracking or display advertising scripts.

Analytics

We use Vercel Web Analytics to measure visits and page views on our public website. Vercel describes this service as cookie-free analytics. It reports page paths, referrers, approximate location and browser/device information. Our integration removes query strings and fragments from analytics page URLs and does not send calculator inputs, contact details or custom events.

You can prevent this analytics integration from loading by enabling your browser's Do Not Track setting or Global Privacy Control. We do not load it on our embedded calculators. Hosting requests and security logs are separate from this analytics integration. See Vercel's analytics privacy information.

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
• To comply with legal obligations

Sharing of information

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

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

Data retention

Hosting and security logs follow our hosting provider's retention settings. Vercel Web Analytics has a one-month reporting window on our current plan; this reporting limit is not a separate guarantee about the provider's deletion schedule. Email correspondence is retained as long as needed to respond and for reasonable record-keeping.

If you are in California (CCPA/CPRA)

Children's privacy

The site is not directed to children under 13 (or 16 in the EU/EEA). We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, contact us and we will delete it.

International transfers

The site is hosted in the United States. If you access the site from outside the US, your information will be transferred to and processed in the US. By using the site, you consent to this transfer.
