Frequently asked questions

Is it 50/50?

Yes. Each flip uses your browser's cryptographic random generator, so heads and tails are equally likely.

Why do I sometimes get a long streak?

Streaks are normal in true randomness. Over many flips the percentage moves towards 50%.

Is Coin Flip free?

Yes. Coin Flip is free to use with no sign-up and no watermark.

Is my information saved or sent anywhere?

No. Everything is calculated in your browser. Nothing you enter is sent to a server or stored.

Does it work on my phone?

Yes. It works in any modern browser on Windows, Mac, Linux, Android and iPhone. Very large files may be slow on older phones.
