Summary
We do not require registration and do not ask you to provide personal information to use the calculators.
Calculator inputs are processed in your browser for the purpose of producing results.
Like most websites, basic technical information (such as IP address and user agent) may be processed by the hosting provider to deliver the site securely.
Information we collect
Calculator Hub does not intentionally collect or store the numbers you enter into the calculators. We do not provide user accounts and we do not operate a backend database for calculator submissions.
The site may generate standard server logs at the hosting layer (for example, to prevent abuse, debug outages, or mitigate attacks). These logs are managed by the hosting provider.
Cookies and analytics
Calculator Hub does not set cookies for authentication or personalization.
If analytics are added in the future, this policy will be updated accordingly.
Third-party services
The site may use third-party open-source libraries bundled with the site assets (for example, math rendering libraries). These are served as part of the site build.
Changes to this policy
We may update this policy from time to time. The updated version will be posted on this page.
