Calculations

Every calculator runs in your browser. The numbers you type are not sent to our servers to compute results.

Saved inputs on your device

To stop a refresh from wiping your work, each calculator remembers its last inputs in your browser’s local storage (keys starting with scp:). This stays on your device, is never sent to us, and you can remove it at any time:

The AI tutor

Only when you press a tutor button or ask a question, the calculator name, your inputs and results, and your question are sent to an AI model through Vercel’s AI Gateway to write an explanation. Nothing is sent on page load. We don’t store these requests beyond short-term operational logs, and you shouldn’t include personal information in questions.

Analytics

We use Ahrefs Web Analytics to count page views. It is cookieless and does not build personal profiles.
