Privacy Policy

Last updated: October 19, 2026

SmartSolarSizer ("we", "us") provides a free solar and inverter sizing calculator at this website. This policy explains what data we collect and how it's used. We've tried to write it in plain language rather than dense legal boilerplate.

Calculator data stays on your device

Every calculation — appliance selections, your electricity bill, tariff, and all results — happens directly in your browser using JavaScript. None of it is transmitted to or stored on our servers. If you close the tab, it's gone.

Information you choose to submit

If you use our contact form, we collect what you enter — your name, email address, subject and message — only to reply to you. The form is delivered to our inbox by Web3Forms, a form-processing service. We don't sell or share this information, and we don't pass it to installers or other third parties.

Analytics

We use Google Analytics to understand how the site is used — for example which pages are visited, roughly which country visitors come from, and what device or browser they use. Google Analytics sets cookies and collects data such as your IP address, pages viewed and time on site; Google processes this data as described in How Google uses information from sites that use its services. We use these reports only in aggregate and don't use them to identify you. You can opt out with the Google Analytics opt-out browser add-on or by blocking cookies in your browser.

We also use Cloudflare Web Analytics, which counts page views without cookies.

Other websites can embed our calculator in a frame. When they do, the calculator is still served from smartsolarsizer.com and this policy, including Google Analytics, applies to it. The rest of that page is covered by the other website's own privacy policy.

Advertising

In the future this site may display advertisements served by Google AdSense and other ad networks. These networks, including Google, may use cookies to serve ads based on your prior visits to this or other websites. You can opt out of personalized advertising through Google's Ads Settings, or generally at aboutads.info. If you visit from the European Economic Area, the UK or Switzerland, we will ask for your consent before personalized ads are shown.

Data we don't collect

We don't require an account or login to use the calculator. We don't ask for or store payment information, government identifiers, or precise location data.

Third-party links

Our guides may link to third-party sites, including installer or manufacturer websites. We aren't responsible for the privacy practices of sites we don't operate — please review their policies separately.

Your choices

You can use the calculator without submitting any personal information at all — the contact form is entirely optional. Where you have submitted information to us, you can request that we delete it by reaching out through our Contact page.

Changes to this policy

We may update this policy from time to time to reflect changes in how the site operates. The "last updated" date at the top will always reflect the most recent revision.
