Privacy Policy

Last updated: November 9, 2026

This policy explains what information is collected when you use calc.kookpit.net ("Calcu", "we", "us") and how it is used. By using the site you agree to this policy.

Information you enter into the calculators

The calculators run in your browser. The numbers, dates and grades you type are processed on your device and are not sent to our servers or stored by us.

Information collected automatically

Like most websites, our server and hosting provider may log technical information such as your IP address, browser type, device type, the pages you request and the time of the request. We use this information to keep the site secure and working, and to understand how the site is used.

Advertising

Calcu is supported by advertising, including rewarded ads that you can choose to watch before a calculation result is shown. Ads are delivered by third-party vendors, including Google. These vendors use cookies, mobile advertising identifiers and similar technologies to serve ads based on your visits to this site and other sites, to limit how often you see an ad, and to measure ad performance.

You can opt out of personalized advertising from Google at Google Ads Settings. You can also opt out of many third-party vendors' personalized advertising at aboutads.info, or at optout.networkadvertising.org. Opting out does not remove ads; it makes them less relevant to you.

For more on how Google uses information from sites that use its services, see How Google uses information from sites or apps that use our services.

Cookies

Calcu itself does not set cookies to track you. Cookies and similar technologies may be set by our advertising partners and, where used, by our hosting or analytics providers. You can block or delete cookies in your browser settings. Some features, such as ads, may not work as intended if cookies are blocked.

Your choices and rights

Depending on where you live, you may have the right to ask what personal information a company holds about you, to request that it be deleted, and to opt out of the sale or sharing of personal information for targeted advertising. Residents of California, other US states with privacy laws, the European Economic Area and the United Kingdom can contact us at the address below to exercise these rights. You can also manage personalized advertising with the opt-out links in the Advertising section above.

Children's privacy

Calcu is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us with personal information, contact us and we will delete it.

Data retention and security

Server logs are kept only as long as needed for security and operations. We use reasonable technical measures to protect the site, but no method of transmission over the internet is completely secure.

Third-party links

The site may link to other websites. We are not responsible for the privacy practices of those sites, so please read their policies.

Changes to this policy

We may update this policy from time to time. The date at the top shows when it was last changed. Continued use of the site after a change means you accept the updated policy.
