Information we collect
Calculator inputs: All calculations run entirely in your browser (client-side JavaScript). The numbers you enter into our calculators are never sent to our servers, stored, or shared with anyone.
Automatically collected data: Like most websites, our hosting provider may log standard technical information such as your IP address, browser type, pages visited, and time of visit, for security and analytics purposes.
Cookies: We use a small number of cookies for basic site functionality (such as remembering preferences). If we display third-party advertising in the future, those advertising partners may use cookies to serve personalized ads. You can disable cookies in your browser settings at any time.
How we use information
We use automatically collected data only to operate, secure, and improve the website. We do not sell personal information to anyone.
Third-party services
Our calculators do not send your inputs anywhere. If third-party advertising (such as Google AdSense) is displayed on this site, those providers have their own privacy policies governing their cookies and data practices.
Children’s privacy
Our calculators are general-purpose tools. We do not knowingly collect personal information from children under 13.
Changes to this policy
We may update this Privacy Policy from time to time. The “Last updated” date at the top reflects the most recent revision.
