CoolCalculators ("we," "us," or "our") respects your privacy. This policy explains what information is collected when you use coolcalculators.cool, how it's used, and the choices you have. We don't run user accounts, and you don't have to sign up for anything to use our calculators.
This site displays ads through Google AdSense. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to our site and/or 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 aboutads.info. To learn more about how Google uses data from sites that use its services, see How Google uses information from sites or apps that use our services.
Where the law requires it, such as for visitors in the European Economic Area, the United Kingdom, and Switzerland, we ask for your consent before advertising cookies are used, through a consent message on the site. You can change your choice at any time through that message or by clearing your browser's cookies.
Some pages on this site contain affiliate links, including links to Amazon. As an Amazon Associate we earn from qualifying purchases. This means we may earn a small commission if you click a link and make a purchase, at no additional cost to you.
When you click an affiliate link, the retailer may set its own cookies to track the referral. Their privacy policies apply once you leave our site.
You can limit tracking through your browser's cookie settings, through Google Ads Settings and aboutads.info as described above, or by using an ad blocker or privacy-focused browser. Blocking cookies won't stop the calculators from working.
Depending on where you live, state privacy laws (such as California's CCPA/CPRA) may give you the right to know what personal information is collected about you, to ask for it to be deleted or corrected, and to opt out of the "sale" or "sharing" of personal information for targeted advertising. We don't keep our own database of visitor information, but advertising cookies placed by our ad partners may count as "sharing" under some of these laws. You can opt out through Google Ads Settings and aboutads.info as described above, or contact us with a request.
If you're in the European Economic Area, the United Kingdom, or Switzerland, the GDPR or UK GDPR gives you rights over your personal data, including the right to access, correct, delete, or restrict it, to receive a copy, and to object to how it's used. You also have the right to complain to your local data protection authority.
Our legal bases are your consent for advertising cookies (which you can withdraw at any time), our legitimate interest in keeping the site secure and working for hosting logs, and your request when you email us. Our service providers, including Google, Netlify, and Amazon, may process data in the United States and other countries under the transfer safeguards those providers maintain. The data controller is CoolCalculators, reachable at hellocoolcal@gmail.com.
This site is not directed at children under 13, and we do not knowingly collect personal information from children. If you believe a child has sent us personal information, contact us and we'll delete it.
Our site may link to third-party websites. We are not responsible for the privacy practices or content of those external sites.
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date.
