Terms of Use

Effective date: 8 November 2026

Last updated: 8 November 2026

These terms are the rules for using the game ("the game"). By downloading or playing it, you agree to them. If you do not agree, please do not use the game.

1. The short version

  • You get a personal license to play, free of charge. You do not own the game. Some things cost money and you buy them from Apple.
  • Coins and other items have no cash value, cannot be given to other people, and never expire.
  • Purchases are final, except where the law or Apple allows a refund. Refunds are handled by Apple.
  • "Remove Ads" removes the full-screen ads between levels for good. Ads you choose to watch for a reward stay available.
  • Please play fairly. We provide the game "as is", and our liability is limited as far as the law allows.
  • We can change or stop the game, but we will give you notice first.
  • Your privacy is covered by our Privacy Policy.

2. Who these terms are between

These terms are between you and Mehmet Aktug, an individual developer, trading as Lumina Studio ("we", "us"), the publisher of the game. Contact: support@luminastudio.ai, Universiteler Mah 1606 Cd B Blok B401, 06800 Ankara, Turkiye (Turkey).

The app is licensed to you, not sold. Apple's Standard Licensed Application End User License Agreement (https://www.apple.com/legal/internet-services/itunes/dev/stdeula/) applies to the app licence together with these terms. If the two disagree about the licence of the app itself, Apple's agreement wins. These terms are between you and us, not Apple. Apple and its subsidiaries are third-party beneficiaries of that agreement and can enforce these terms against you once you accept them. Apple has no duty to give support or maintenance for the game and is not responsible for the app or for claims about it; those are our responsibility, and you can contact us at the address above.

3. Using the game

The game is not directed to children. It has no age check, and players of any age may play. If you are under the age of majority where you live, ask a parent or guardian to agree to these terms with you.

We give you a limited, personal, non-exclusive, non-transferable, revocable license to install and use the game on iPhones that you own or control, for your own non-commercial entertainment, as the Apple Standard EULA allows. Please do not copy, modify, sell, rent, lease or share the game, or make a version of it based on ours; do not reverse engineer, decompile or try to extract the source code, except where the law gives you that right; do not remove notices of ownership; do not remove protections that keep purchases and the hearts timer fair, for example by setting your phone's clock back or editing saved files; do not use cheats, bots or tools that interfere with the game; do not interfere with ads or purchases; and do not use the game to break any law or to harm others. If you break these rules, we may reset progress or remove items gained unfairly. We will act proportionately and in line with the law.

The game, including its code, art, sounds, levels, word selections, text, names and logos, belongs to us or to the people who licensed them to us and is protected by copyright, trademark and other laws. Some word lists, fonts and sounds are used under open licenses; their credits and licences are in the app under About. These terms give you no ownership rights.

4. Hearts, coins, hints and other items

  • Coins, hints, hearts, boosters and passes ("items") are part of the game. You earn some by playing and can buy some. You receive a limited license to use items inside the game. You do not own them.
  • Items have no cash value, cannot be transferred, sold, gifted or exchanged with other people, and cannot be turned back into money. Any attempt is void.
  • Coins you have paid for do not expire. We will not remove coins you earned or bought because of the passage of time. Time-limited passes (for example unlimited hearts for 30 minutes) run for the time that is written on them, starting when you start the first level that uses them.
  • Items live in your game on your device and, if you use iCloud, in your iCloud snapshot. If you remove the app, reset the game or lose your device and have no iCloud snapshot, items can be lost. Apple lets us restore one-time purchases but not coins or other consumable items. We do not offer a goodwill restore of items through support, so keep iCloud on if you want a backup.
  • We may change prices, rewards and balance values in updates. This will not remove coins you already hold.
  • We may correct a balance that is wrong because of a bug, and we may remove items that came from an abuse of a bug.

5. Purchases

  • All purchases are made in the App Store with your Apple Account and are charged by Apple, in the currency and at the price Apple shows you. Taxes are included as Apple states.
  • Purchases are final, except where the law or Apple allows a refund. We do not process payments and cannot refund them. You can ask Apple for a refund at https://reportaproblem.apple.com or through your Apple Account support. Refunds are decided by Apple, not by us. If Apple refunds a purchase, we may remove the coins or items it gave you, or the Remove Ads entitlement.
  • A failed or cancelled purchase gives you nothing. If you are charged and do not receive your item, restart the game first, and then contact Apple or us.
  • Right of withdrawal. Your legal rights as a consumer, including any right to withdraw from a digital purchase where the law gives one, are not changed by these terms. Because digital content is delivered right away, the right to withdraw may end once delivery starts, as the law allows in your country.
  • Restore Purchases. One-time purchases such as Remove Ads can be restored on your devices with the Restore Purchases button (in Settings and in the shop). Coins and other consumable items cannot be restored from Apple; they come back only through your iCloud snapshot.
  • Prices and what a product contains can change for new purchases. A price change does not affect what you already bought.
  • Ask to Buy, Family Sharing and Screen Time limits are handled by Apple.

6. Remove Ads

"Remove Ads" is a one-time purchase. It removes the full-screen ads that appear between levels (interstitials) and any banner ads the game may ever show. It does not remove rewarded ads: those are video ads that you choose to watch in exchange for a reward such as a hint or a heart, and they stay available because you can always decline them. Remove Ads covers the app on the Apple Account that bought it; it can be restored on your other devices that use the same Apple Account.

7. Ads and privacy

The game is free to play and shows ads from Google's advertising software (Google AdMob), which shows ads from other advertisers and ad partners. We do not control the content of third-party ads and are not responsible for the products they promote. Rewarded ads are optional: you choose to watch one and see the reward first, and the reward is given when the ad finishes. If you close it early or no ad is available, you get nothing and can try later. How data is used for ads, what you can choose and how to change your choice is explained in the Privacy Policy. If you see an ad that is inappropriate or misleading, use "Report an ad" on the Support screen, and we pass reports on to the ad network.

8. Your content and feedback

The game has no user-created content. If you send us a message, a word report or an idea, you let us use it to improve the game without paying you, and without giving you a claim on the game.

9. Changes, updates and ending the game

We may update the game, add or remove features, change ads, prices and the balance of the game, end support for old iOS versions, and fix bugs. You may need to update the app to keep playing. Some features need an internet connection, such as ads and purchases, and sometimes the game may be unavailable, for example for maintenance. If we ever shut the game down, we will give notice of at least 90 days in the game and on our website, and we will keep it possible to restore your purchases during that time. We do not compensate for coins or items you have not used when the game stops, except where the law says otherwise.

10. Ending your use

You can stop at any time by removing the app. Use the reset in Settings first if you also want your data removed from your phone. We may suspend or end your access if you seriously or repeatedly break these terms, or if the law requires it. Where it makes sense, we will warn you first. When these terms end, your license ends. Sections that by their nature continue (ownership, disclaimers, liability, law) continue after the end.

11. Disclaimers and liability

As far as the law allows, the game is provided "as is" and "as available", without promises that it will be error-free, uninterrupted or fit for a particular purpose. We try to keep it free of mistakes and the puzzles solvable, but we cannot promise that it will always work without errors, interruption or loss of saved data, or that word lists are free from mistakes. We are not responsible for third-party services such as Apple, Google and other ad partners. As far as the law allows, we are not liable for indirect or consequential loss, lost profits, lost data or lost items, and our total liability to you for anything connected with the game is limited to the greater of the amount you paid us through the App Store in the twelve months before the claim and 50 US dollars. We do not exclude or limit liability for death or personal injury caused by our negligence, for fraud, for intentional harm or gross negligence where the law says so, or for anything else the law does not allow us to exclude, and nothing in these terms limits your rights as a consumer that cannot be waived. Some countries do not allow certain limits, so parts of this section may not apply to you.

12. Governing law and courts

These terms are governed by the laws of Turkiye (Turkey). The courts of Ankara will handle disputes, unless your local consumer law gives you the right to use your own country's courts or laws. If you live in the EU or UK, you keep the protection of the mandatory consumer rules of your country. Disputes about the licence of the app can also fall under Apple's agreement.

13. Changes to these terms

We may change these terms, for example when we add features. The new version will have a new "Last updated" date and, for changes that matter or make your position worse, we will tell you in the game before they apply to you. If you keep playing after the effective date, you accept the new terms. If you do not agree, stop playing and remove the game.

14. General

  • If part of these terms cannot be enforced, the rest still applies.
  • If we do not enforce a right right away, we do not give it up.
  • You may not transfer your rights under these terms. We may transfer ours as part of a sale or reorganization of the game.
