FAQ
Is the coin flip truly random?
Yes. We use the browser's built-in cryptographically secure random number generator (crypto.getRandomValues). Each flip result is completely random and fair, unaffected by any external factors.
Can I use this for decision making?
Absolutely. Coin flipping is a classic decision-making aid. When faced with two difficult choices, a coin toss can help break the deadlock. However, it's best reserved for non-critical decisions.
Is my data sent to a server?
No. All coin flip generation and statistics are processed locally in your browser. No data is transmitted over the network, protecting your privacy.
What are the odds of heads vs tails?
Theoretically, a fair coin has a 50% probability for both heads and tails. As the number of flips increases, the actual statistical ratio will approach 50:50.
How long is the flip history kept?
Flip history is saved to your browser's local storage and persists across sessions. It will only be deleted when you manually click the clear button.
