Is this coin flip really 50/50?

Yes. Each flip draws from Math.random(), which is statistically fair over large samples. Real coins actually have a slight physical bias; a software coin does not.

Does it use cryptographically secure randomness?

No. Coin flips use Math.random(), which is appropriate for entertainment. Do not use the result as a password, secret, or anything an attacker could benefit from predicting.

Is my flip history stored on a server?

No. The tool runs entirely in your browser. Your flip history is kept in memory for the session and discarded when you leave the page.
