A: Yes! The app uses your browser's cryptographically secure random number generator. The results are just as random as flipping a real coin (when bias is set to 50%).

A: No! It runs directly in your web browser. Just open the HTML file or visit the website.

A: Mostly yes! Once you've loaded the page once, it can work offline. However, if you refresh, you'll need internet to reload resources.

A: Yes! Completely free to use.

A: They're saved in your browser's localStorage on your device. They stay there until you:

• Click the "Clear" button
• Clear your browser data
• Use private/incognito mode

A: Yes! Click "Export" to download your statistics as a JSON file. You can then email or share this file.

A: Reasons could be:

• You haven't flipped enough times (need 100+ for accuracy)
• Bias setting is not at 50% (check Settings)
• Just unlucky! With small numbers, weird splits happen

A: After many flips (100+):

• 50% heads, 50% tails = Perfect fairness
• 45-55% range = Normal variation
• Below 40% or above 60% = Check your bias setting!

A: Currently you can have one custom theme at a time. To change it, upload new images in Settings → Custom.

A: Easy! Just open Settings and select "Classic Gold" or "Silver" instead of Custom.

A: No, only static PNG or JPEG images are supported. The coin's 3D spinning provides the animation!

A: It depends:

• Regular browsing: Yes, they're saved
• Private/Incognito mode: No, they're lost when you close
• If you clear browser data: No, they're deleted

A: WebGL is a technology that lets browsers show 3D graphics (like our coin). Most modern browsers support it. If yours doesn't, the app will offer 2D mode instead.

A:

• 3D Mode: Realistic spinning coin, beautiful graphics, smooth physics
• 2D Mode: Simple flip animation, still works for getting results, but less pretty

A: Very little! The app is under 1MB including graphics. No constant internet connection needed.

A: No! Everything happens in your browser. No data is sent anywhere. Your statistics stay on your device only.

A: Yes! Fully optimized for mobile devices. Tap the coin to flip!

A: Haptics = vibration. When enabled, your phone vibrates when you flip. Makes it feel more real!

A: 3D graphics can be demanding. Try enabling "High Performance Mode" in Settings to speed it up.

A: On some browsers, yes! Look for "Add to Home Screen" in your browser menu if the app supports PWA.

A: The coin flip itself is completely fair and random (when bias = 50%). However, for truly important decisions, you should probably think carefully rather than rely on random chance! 😊

A:

1. Flip three times
2. Count how many heads vs tails you got
3. Whichever has more (2 or 3) wins!

Example: Heads, Tails, Heads = Heads wins (2 to 1)

A: Yes, but that defeats the purpose of a coin flip! If you want, set bias to 100% (always heads) or 0% (always tails) in Settings.

A: Mathematically, infinite! But realistically:

• 3 in a row: Common (~12% chance)
• 5 in a row: Rare (~3% chance)
• 10 in a row: Very rare (~0.1% chance)
• 20 in a row: Extremely rare (1 in a million!)

A: Not in this app! Real coins can theoretically land on edge (about 1 in 6000 chance), but we don't simulate that. You'll always get heads or tails.

A: Two possibilities:

• You're incredibly lucky! (Chance: 1 in 1,267,650,600,228,229,401,496,703,205,376)
• You accidentally set bias to 100% in Settings 😉
