The rules of the game.

These terms apply to the YYK app and yyk.now. They're an agreement between you and [Company legal name], [registered address], [country] ("YYK", "we", "us"). By creating an account or using the app, you accept them. Our privacy policy explains how we handle your data.

You need to be at least 16 to use YYK.

YYK gives general fitness challenges. It isn't medical advice and it doesn't know your health. Talk to a doctor before starting if you're pregnant, injured, recovering from surgery, or have a heart, lung or joint condition.

• Stop straight away if you feel pain, dizziness, chest tightness or shortness of breath.
• Only answer a call when it's safe: never while driving, crossing a road or operating anything dangerous.
• Make sure you have room to move and a stable surface for your phone.

You can skip any call. Skipping may cost you a streak, never your safety.

Give us accurate details and keep your login to yourself. You're responsible for what happens on your account. Tell us at hello@yyk.now if you think someone else is using it.

YYK sends calls at random times inside the hours you allow. Calls rely on your phone's notifications, so they can arrive late or not at all if notifications are off, your battery saver is on, or your connection drops. We can't promise every call lands.

Rep counting uses your camera and works best with your whole body in frame and decent light. Counts can be wrong. How the camera is used is set out in our privacy policy.

Don't try to fool the rep counter, automate calls, reverse-engineer the app, or use YYK to harass anyone. If you do, we can reset your progress or suspend your account. We'll tell you why, and you can reply to us if you think we got it wrong.

Some features need a paid subscription. Prices are shown in the app before you pay. Subscriptions are billed through the App Store or Google Play, renew automatically and can be cancelled in your store account settings at least 24 hours before renewal. Refunds follow Apple's and Google's refund policies.

If we change a price, we'll tell you in advance and the new price applies from your next renewal.

YYK, its name, logo, characters, art and code belong to us. We give you a personal, non-transferable licence to use the app for as long as you have an account. Your data stays yours; the privacy policy explains what we do with it.

You can delete your account at any time from Settings → Account → Delete account. We can suspend or close accounts that break these terms, and we'll tell you why unless the law stops us. If we ever shut YYK down, we'll give you at least 30 days' notice.

YYK is provided "as is". We work to keep it running and accurate, but we don't promise it will be uninterrupted or error-free. As far as the law allows, we're not liable for indirect losses, and our total liability is limited to what you paid us in the 12 months before the claim. Nothing in these terms limits liability that can't be limited by law, or your rights as a consumer.

These terms are governed by the laws of [country]. If you live in the EU or UK, you keep the protection of your local consumer law and can bring claims in your local courts.

If we change these terms in a way that matters, we'll tell you in the app or by email before the change takes effect.
