Calculator Hub respects the privacy of its visitors. This policy explains what information this site collects, how it is used, and what choices you have. This site does not require registration and does not actively collect personal information such as your name or email address. Numbers you type into a calculator are calculated in your own browser and are never sent to a server.
Information We Collect
This site has no registration or login, and does not collect personal information such as your name, email address, or phone number. Calculator inputs are processed locally in your browser and never leave your device. The server may record routine technical information when serving the site, such as the time of access, pages visited, browser type, and IP address, only to keep the site running and to troubleshoot issues. It is not used to identify individual visitors.
Cookies and Local Storage
This site uses browser local storage to remember your preferences, such as the dark / light theme. This data stays in your own browser and is not uploaded to any server. This site currently does not use advertising tracking cookies; if advertising services are added in the future, this policy will be updated.
Third-Party Services and External Links
Pages on this site may contain links to third-party websites. Once you click them, the third party's privacy policy applies, and this site is not responsible for their content. If third-party analytics or advertising services (such as Google AdSense) are added in the future, they may use cookies to provide statistics or display ads. Please refer to the updated version of this policy at that time.
Your Rights
You can clear data stored locally by this site, including cookies, at any time through your browser settings, or simply stop using this site. Because this site does not collect personal identity information, there is no personal account data to access, correct, or delete.

Policy Updates
This policy may be updated as the site's services change. The updated version will be published on this page, and the "Last updated" date at the top of the page will show when it changed.
