Calculator inputs

All calculations run client-side in your browser using JavaScript. The numbers you type into a calculator are never transmitted to our servers and are not stored by us. Your last few used tools are remembered only in your own browser's local storage, so you can find them again — this data never leaves your device.

Analytics

We use standard web analytics to understand aggregate traffic patterns (pages viewed, approximate location, device type). This data is not tied to the values you enter into any calculator.

Advertising

We display ads through third-party ad networks (such as Google AdSense), which may use cookies to show relevant ads. You can opt out of personalized advertising through your browser or ad settings, and through Google Ads Settings.

Cookies

We use functional cookies/local storage for theme preference (dark/light mode) and recently used tools. Third-party ad and analytics providers may set their own cookies as described above.

Your rights

You can clear all locally stored ToolHub data at any time by clearing your browser's site data for this domain. For data requests, contact hello@toolhub.example.
