Expressions you enter

All calculations in SciKey run as JavaScript inside your browser. The expressions and results you enter are never sent to any server.

Information stored in your browser

For convenience, the following is stored in your browser's localStorage: calculation history (last 50), memory and variable values (Ans, M, x, y, z), angle unit, display format and significant-digit settings, and the light/dark theme. This information stays on your device, and nothing that identifies you personally is stored. You can delete it at any time with the calculator's 'Clear history' and 'Reset variables' buttons or in your browser settings.

Advertising

This site may show Kakao AdFit advertisements to cover running costs. Ad providers may use cookies and similar technologies to serve ads and measure their performance, subject to their own privacy policies. What you type into the calculator is not passed to ad providers.

Server logs

The site is served by static file hosting (Cloudflare Pages). The hosting provider may process standard web server logs, such as IP addresses and request times, for security and service operation.
