Cookie Policy

Cookies are small files a website can store in your browser, and similar technologies such as local storage and web beacons serve related purposes. This page explains which ones are in use on Solar DIY Project and what each is for.

Solar DIY Project is a static site with no accounts, no login, and no checkout, so we set no cookies of our own for tracking or identification. The cookies you encounter here come from our hosting provider and from third-party advertising.

Strictly necessary

Our hosting provider may set cookies required for security, load balancing, or abuse prevention. These are needed for the site to be served reliably and cannot be switched off through a preference setting, though your browser can still block them.

Local storage used by the calculators

The calculators on this site may store the values you enter in your browser's local storage so your figures survive a page refresh. This is not a cookie, it is not sent to any server, and it contains nothing but the numbers you typed. Clearing your browser's site data removes it.

Advertising cookies

This site is supported by display advertising served by third-party networks, including Google. Those networks set cookies to select adverts, limit how often you see the same one, and measure performance.

• Third-party vendors, including Google, use cookies to serve advertisements based on your prior visits to this and other websites.
• Google's use of advertising cookies enables it and its partners to serve advertisements to you based on your visits to this site and other sites on the internet.
• Advertising vendors may also use web beacons to collect information as a result of serving adverts on this site.

We do not control which adverts are shown, and we receive no personal information about you from the advertising network.

If we add analytics, embedded media, or any other service that sets cookies, this page will be updated before that service goes live, and the date at the top will change. See the privacy policy for how data is handled more broadly.
