Terms of Use

Version 4 · 2026-11-09

Last updated: 9 November 2026

Welcome to YOPZO! These Terms of Use ("Terms") are an agreement between you and Sabahattin Çalışkan, who develops YOPZO under the name Caliskan Games ("we", "us"), about your use of the YOPZO apps for iOS and Android and the YOPZO web player (together, "YOPZO"). Our Privacy Policy, Community Guidelines and User Content Rules also apply. By accepting these Terms or using YOPZO, you agree to them.

1. Who we are

YOPZO is provided under the name Caliskan Games by Sabahattin Çalışkan, an independent developer (a natural person) living in Turkey; there is no company behind it. You can reach us at sebocaliskan@hotmail.com. The developer's home address is not published in these Terms; if the law requires a written notice, the postal address to use will be sent to you by email.

2. Who can use YOPZO

• You must be at least 13 years old. If you are under 13, you may not use YOPZO.
• If you are under 18 (or under the age of majority where you live), you need permission from a parent or legal guardian to use YOPZO, and they should review these Terms with you.
• Please answer the age question honestly. Some features, including ads and some content, depend on your age tier.

3. Your account

• When you first open YOPZO, we automatically create a guest account. The account is tied to this device; we don't ask for an email address, phone number or password.
• So losing your device, deleting the app or clearing its data may mean you lose your account and progress for good. (If you bought Premium, you can restore the purchase to your new account with the same Google account; see section 8.)
• You are responsible for what happens on your account. Keep your device secure and don't sell, share or transfer your account.
• Your nickname must follow our Community Guidelines. We may change or remove nicknames that don't.

4. Your license to use YOPZO

YOPZO and everything in it — software, questions, characters, avatars, artwork and sounds — belong to us or our licensors. We give you a personal, limited, non-exclusive, non-transferable and revocable license to use YOPZO for your own non-commercial entertainment, in line with these Terms and the rules of the app store you got it from. All rights we don't expressly give you remain ours.

If no opponent is found, AI opponents may join the game.

5. A free game funded by ads

• YOPZO is free to play; no part of the core game costs money. There are no subscriptions. On Android, one optional purchase may be offered: Yopzo Premium (section 8). Google Play takes the payment; we will never ask you for payment details ourselves.
• YOPZO is funded by ads. Only adult players (18+) may see ads. We don't show ads to teens (13–17) or to players whose age we don't know. Your ad choices are explained in the Privacy Policy.
• Ads never appear in the middle of a round, and your first games are always ad-free.

6. Rewarded ads and unlocks

• Some extras can be unlocked by choosing to watch a rewarded ad — for example, unlocking a card frame, a profile background or a result theme, or sending a poll to more people. The app shows what you will get, and for how long, before you choose.
• Players with Premium don't see rewarded-ad offers, because these extras are already unlocked for them.
• Rewarded ads are always optional. You can always say "No thanks" and keep playing normally.
• You get the reward only after the ad network confirms that the ad was completed. If the ad is closed early or can't be confirmed, no reward is given, and you can try again later.
• Rewarded ads have daily limits, and offers depend on your age tier, your ad choices and where you live.
• You can also reach the same extras through XP, levels and streak milestones, so nothing in YOPZO is available only by watching ads. This is how players who don't see ads, including all teens, unlock them.

7. Virtual items and rewards

XP, levels, streaks, rewards (including those unlocked with rewarded ads or with Premium), cosmetics and other in-game items are licensed to you for use in YOPZO; you don't own them. They have no monetary value: they cannot be bought individually, sold, exchanged for money, transferred or traded. Time-limited unlocks end when their time runs out. We may adjust how virtual items and rewards work, for example to fix bugs or keep the game fair; our commitments about Premium are in section 8. This does not affect your mandatory rights.

8. Yopzo Premium (Android only)

• What it is. Yopzo Premium is an optional package you buy through Google Play with a one-time payment. It is not a subscription: it doesn't renew and you won't be charged again. The price is shown on Google Play's payment screen before you buy. In this version, Premium is offered only in the Android app.
• What it includes. Playing without ads (no end-of-game ads and no ad offers); the looks that can be unlocked with rewarded ads, unlocked right away; sending your polls to more people and playing solo practice rounds without watching ads; a Premium supporter badge and two special looks. The Premium page in the app shows the details before you buy.
• No advantage in the game. Premium gives no hints, extra time, extra points, extra XP or ranking advantage. The features and looks Premium unlocks can also be reached by watching ads or by levelling up; for example, the two special looks unlock for everyone at level 40.
• Who it's offered to. We show the Premium offer only to adult (18+) players. Google Play takes the payment, and Google Play's own terms and payment rules also apply.
• It's personal. Premium is for your own use only; it can't be sold, transferred or shared between accounts. If your own YOPZO account changes (for example, when you move to a new phone), tap "Restore purchases" on the Premium page with the same Google account: the purchase moves to your new account and is removed from the old one. Deleting your account does not refund your payment; you can restore the purchase to a new account with the same Google account.
• How long it lasts. Once you buy Premium, it stays on your account for as long as YOPZO is offered (this is what "lifetime" means). We may improve or change what Premium includes, but we won't take away the core of what you paid for, meaning playing without ads and the looks unlocked at purchase, without a valid reason (for example a refund, a chargeback, cheating or abuse, or a legal requirement). If, through no fault of yours, we can no longer offer YOPZO or Premium permanently, we will announce it in the app with reasonable notice where possible and provide any refund or compensation required by law.
• Right of withdrawal. Premium is digital content that unlocks on your account the moment you buy it. On the purchase screen, next to the buy button, we state clearly that the payment is one-time, that it is not a subscription, that Google Play handles the payment, and that because the content unlocks immediately your right of withdrawal ends at the moment of purchase. By tapping the buy button, you ask for the content to be unlocked immediately and acknowledge that you therefore lose your right of withdrawal. In Turkey this is based on Article 15(1)(ğ) of the Distance Contracts Regulation (services performed instantly in electronic form and intangible goods delivered instantly to the consumer); in the European Union, on Article 16(m) of Directive 2011/83/EU (digital content not supplied on a tangible medium, where performance has begun with the consumer's prior express consent and acknowledgement). Google Play sends the purchase confirmation and receipt by email.
• Refunds. Within 48 hours of buying, you can ask for a refund through Google Play; Google decides based on the details of the purchase. After 48 hours, write to sebocaliskan@hotmail.com with your order number (the code starting with "GPA."), and we will review your request under Google Play's rules and applicable law. If a purchase is refunded, cancelled or charged back, Premium and the looks unlocked only by Premium are removed from your account; anything you earned through levels, streaks or ads stays. Your statutory rights, such as those for faulty digital content under Turkey's Consumer Protection Law No. 6502 and the mandatory consumer law where you live, are not affected.

9. Acceptable use

When using YOPZO, you must not:

• break our Community Guidelines or User Content Rules;
• harass, bully, threaten, target or shame anyone, or post hateful, sexual, violent or illegal content;
• share anyone's private information, including your own;
• impersonate others or use misleading nicknames;
• use cheats, bots, scripts, exploits or unauthorized software, or abuse bugs (please report them instead);
• interfere with or overload our servers, or try to access accounts or data that aren't yours;
• copy, modify, resell or commercially exploit YOPZO or its content (including our question packs), or reverse engineer the app except where the law allows;
• use YOPZO for advertising, spam or scams;
• create new accounts to get around a ban or the age rules.

10. Your content

"Your content" means anything you create in YOPZO, such as free-text answers, memories, statements, personal quizzes and your nickname.

• You keep ownership of your content and are responsible for it. Only share content you have the right to share.
• You give us a worldwide, non-exclusive, royalty-free license to store, copy, display and transmit your content only as needed to operate, secure and moderate YOPZO — for example, to show your answer to the players in your room or your quiz to people who have its link.
• This license ends when your content is deleted under our Privacy Policy, except where we need to keep a copy for a pending report or for legal reasons.
• We don't use your content in advertising.

11. Moderation, reports and blocking

• You can report any player content and block any player.
• We use automatic word filters and we review reports. We may remove content, limit features, or suspend or permanently remove accounts that break these Terms. Where needed for safety, we may act without prior notice.
• We have zero tolerance for content or behavior that sexualizes or endangers children. We remove it, ban the account and report it to the authorities where required.
• When we restrict your content or account, we will tell you why where the law requires it. If you think we made a mistake, you can ask us to review the decision by writing to sebocaliskan@hotmail.com with your friend code.

12. Third-party services

YOPZO uses services from third parties such as Apple and Google (including AdMob and Firebase), which have their own terms. Ads are provided by third parties, and we are not responsible for third-party websites or offers you reach through an ad.

13. App Store and Google Play

• These Terms are between you and us, not Apple or Google. We, not Apple or Google, are responsible for YOPZO and its content.
• Apple has no obligation to provide maintenance or support for YOPZO.
• To the extent permitted by law, Apple has no warranty obligation for YOPZO.
• We, not Apple, are responsible for any claims relating to YOPZO, including product liability claims, claims that it does not meet legal or regulatory requirements, consumer protection or privacy claims, and claims that it infringes someone's intellectual property.
• You confirm that you are not located in a country subject to a US Government embargo or designated as a "terrorist supporting" country, and that you are not on any US Government list of prohibited or restricted parties.
• Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

14. Changes to YOPZO

We keep improving YOPZO, so features and content may change or be removed. If we decide to shut YOPZO down, we will give reasonable notice in the app where possible. Our commitments about Premium are in section 8. Your mandatory rights are not affected.

15. Ending your use of YOPZO

• You can stop using YOPZO and delete your account at any time in Profile → Settings → Delete account.
• We may suspend or end your access if you seriously or repeatedly break these Terms, or if we must do so to protect other players or comply with the law. Where appropriate, we will warn you first.
• When your access ends, your license and virtual items, including rewards, end too. Section 8 applies to Premium: if you delete your own account, you can restore the purchase to a new account with the same Google account; if we end your access because you seriously broke these Terms, Premium ends too, without affecting your mandatory consumer rights. Sections that by their nature should continue (such as 10, 16, 17 and 18) remain in effect.

16. Disclaimers

We work hard to keep YOPZO fun and running, but it is provided "as is" and "as available". To the extent permitted by law, we don't promise that YOPZO will always be available or error-free, or that every question and answer is free of mistakes. Your statutory rights, such as legal guarantees for digital content, are not affected.

17. Limitation of liability

• Nothing in these Terms limits our liability for intent or gross negligence, fraud, death or personal injury, or any other liability that cannot be limited by law, and nothing affects your mandatory consumer rights.
• Subject to that, we are not liable for losses that were not reasonably foreseeable, or for losses caused by events outside our reasonable control.
• Subject to the same exceptions and to the extent permitted by law, we are not liable for indirect losses, loss of data or loss of profit. Your rights under consumer law are not affected.

18. Governing law and disputes

• These Terms are governed by the laws of the Republic of Turkey.
• If you are a consumer in Turkey, you may apply to the Consumer Arbitration Committee or the Consumer Court at your place of residence or where the transaction took place, within the monetary limits set each year.
• If you are a consumer in another country, you also keep the protection of the mandatory laws of your country of residence and may bring claims before the courts of that country.
• Before going to court, please write to sebocaliskan@hotmail.com — most problems can be solved quickly.

19. Changes to these Terms

We may update these Terms, for example when we add features or the law changes. When we do, we will update the version number and date and ask you to review and accept the new version in the app. If you don't agree, you can stop using YOPZO and delete your account. Changes do not apply retroactively.

20. General

• If any part of these Terms is found unenforceable, the rest stays in effect.
• If we don't enforce a right right away, we don't give it up.
• You may not transfer your rights under these Terms. We may transfer ours to a successor, for example in a merger, without reducing your rights.
• These Terms are available in Turkish and English. If they conflict, the Turkish version prevails unless mandatory law where you live says otherwise.
