This Privacy Policy explains how CleanTech Explained (“we”, “us” or “our”) collects, uses and protects information when you visit https://cleantechexplained.com.
Who we are
CleanTech Explained is run by Dagus R Djuanda, based in Indonesia, who is responsible for the personal information described in this policy. You can reach us at hello@cleantechexplained.com.
Information we collect
Information you give us: if you email us, or subscribe to a newsletter if we offer one, we collect your email address, your name if you provide it, and the content of your message.
Information collected automatically: like most websites, we automatically collect basic technical information such as your IP address, browser type, device type, pages visited, time spent on pages and the website that referred you. This information is collected through server logs, security tools and, where used, cookies and similar technologies.
How we use information
We use the information we collect to operate and improve the website, understand which content is most useful to readers, send a newsletter to people who have subscribed, respond to messages and correction requests, and keep the website secure.
We do not sell your personal information.
Legal basis
If you are in the European Economic Area, the United Kingdom or Switzerland, we process your information on the basis of our legitimate interest in running and securing the website, your consent where required (for example, for advertising cookies), and to reply when you contact us.
Cookies
Cookies are small text files stored on your device. We use cookies to make the website work and, where advertising or analytics tools are in use, to show ads and understand how visitors use the site. You can block or delete cookies through your browser settings, although some parts of the website may not work properly without them.
Advertising (Google AdSense)
We may use Google AdSense to display ads. If we do, third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website and other websites. Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visits to this and other sites on the internet.
You can opt out of personalized advertising by visiting Google Ads Settings. You can also opt out of some third-party vendors’ use of cookies for personalized advertising at www.aboutads.info/choices. To learn more, see how Google uses information from sites that use its services.
Visitors from the European Economic Area, the United Kingdom and Switzerland will be asked for consent before personalized ads are shown, if ads are in use.
Analytics
We use data from Google Search Console, which shows how our pages appear in Google Search and does not place cookies on your device. We may add Google Analytics in the future. If we do, it will collect information such as pages visited and time spent on the site. You can learn how Google uses this data at policies.google.com/technologies/partner-sites and opt out using the Google Analytics Opt-out Browser Add-on.
Affiliate links
Some pages may contain affiliate links. When you click one, the retailer may place a cookie on your device to record that you came from our website. This lets them pay us a commission if you make a purchase. See our Affiliate Disclosure for more information.
Newsletter
If we offer a newsletter and you subscribe, we use your email address only to send you the newsletter and related updates. Every email includes an unsubscribe link. A newsletter may be delivered through a third-party email service provider, which processes your email address on our behalf.
Service providers
Our website is hosted by Hostinger, and we use Wordfence to protect it from attacks. These services process technical data such as IP addresses on our behalf. Some of these providers may process data outside your country.
Third-party links
Our articles link to external websites. We are not responsible for the privacy practices of those websites, and we encourage you to read their privacy policies.
Data retention and security
We keep personal information only as long as needed for the purposes described in this policy. We use reasonable security measures to protect it, but no method of transmission or storage over the internet is completely secure.
Your rights
Depending on where you live, you may have the right to access, correct or delete your personal information, to object to or restrict certain processing, and to withdraw consent at any time. To make a request, contact us at hello@cleantechexplained.com. You also have the right to complain to your local data protection authority.
Children’s privacy
This website is not directed at children under 13, and we do not knowingly collect personal information from children.

We may update this Privacy Policy from time to time. The date at the top of this page shows when it was last updated.
