Privacy policy

Last updated: June 2026.

CalcHubis built to be private by default. This policy explains what we do and don’t collect.

What we don’t collect

• We do not ask for or store your name, email, or any account details — there are no accounts.
• The numbers you enter into a calculator are processed entirely in your browser and are never transmitted to us or saved on a server.
• We do not sell, rent, or share personal information.

Advertising

CalcHub is funded by display advertising provided by Google AdSense. Google and its partners may use cookies to serve ads based on your prior visits to this and other websites. You can learn about your choices and opt out of personalized advertising at Google Ads Settings (opens in a new tab).

Cookies

We use a single local-storage flag to remember that you’ve dismissed the cookie notice. Advertising partners may set their own cookies as described above. You can clear cookies at any time through your browser settings.

Analytics

We may use privacy-respecting, aggregate analytics to understand which calculators are useful. This data is not tied to your identity.
