Privacy

What you type into a calculator or the chat box is processed in your browser and is never sent to our servers.

The optional on-device AI model is downloaded once from a public model host and then runs locally on your device. We do not log questions, values or results.

We use advertising provided by Google AdSense, which may use cookies to show and measure ads; see Google’s policy at https://policies.google.com/technologies/ads. Advertising scripts never receive what you type into calculators.

A small preference (whether you turned the AI model on) is kept in your browser’s local storage.
