Privacy Policy

Last updated: September 27, 2026.

CalcHub is an independent online calculator project. It does not require visitor accounts.

Calculator Inputs

Calculator inputs are processed in your browser to display results. CalcHub does not intentionally store calculator inputs on a server. Do not enter sensitive personal, medical, financial or account information unless you are comfortable using it in your own browser.

Technical Data

Hosting and security providers, including Cloudflare Pages, may process standard technical data such as IP address, browser type, device type, requested URL and timestamps to deliver and protect the site.

Advertising and Cookies

CalcHub may use Google AdSense. Google and its partners may use cookies or similar technologies to serve, measure and personalize ads depending on your settings, consent choices and applicable law.

If advertising is disabled on a page, that page may still be delivered through Cloudflare and may still use ordinary technical logs.

Local Storage and Forms

The current static site does not provide user accounts. It does not include a working contact form. If future features use localStorage, forms or analytics, this policy should be updated before launch.

Children and Sensitive Use

CalcHub is not designed to collect information from children and should not be used to submit personal profiles. Health calculators are educational screening estimates, not medical advice.

Contact

There is no public contact form on this static site. Use the channel through which the site owner provided this website if you need to raise a privacy question.
