Terms of Use
Last updated: October 13, 2026
This is a translation. In case of any difference, the French version prevails.
1. Who publishes Cubix
Cubix is a game designed and published by SUNDER DEV, the trade name of Ahmed Sanoko, a sole trader registered in the French National Business Register (SIREN 980 468 870, SIRET 980 468 870 00020, APE code 6201Z), 69 rue de Mon Désert, 54000 Nancy, France. Contact: contact@sunderdev.com.
2. The game
Cubix is a free game, distributed on the App Store and Google Play. By installing the game, you accept these terms as well as those of Apple or Google for downloads and purchases. The journey, free play and 2-player duels can be played offline; the leaderboard, online duels, purchases and VIP codes require an internet connection.
3. Profile and username
On first launch, the game asks you for a username and your age. Your age stays on your phone. Your username is visible to other players on the leaderboard and in duels: it must not be insulting, discriminatory or sexual in nature, or impersonate anyone, and it must not contain any personal information. The game rejects inappropriate words; SUNDER DEV may also remove a reported username or a score clearly obtained by cheating.
4. Leaderboard and online duels
The leaderboard and online duels run through Unity’s servers. Play fair: any attempt to cheat, modify the game or disrupt other players’ games may lead to the removal of your scores and to your access to online features being blocked. These services may be interrupted for maintenance or in the event of an outage.
5. In-app purchases
The game offers packs of hint tokens and gems, at the price shown in the App Store or Google Play at the time of purchase. Payment is processed by Apple or Google; SunderDev never receives your payment information. Hint tokens and gems are credited as soon as the payment is confirmed.
This is digital content supplied immediately: by confirming the purchase, you request its immediate performance and acknowledge that you lose your right of withdrawal (Article L. 221-28, 13° of the French Consumer Code). For a refund, contact Apple or Google, which apply their own rules. A minor must have their parents’ permission to make a purchase; Apple’s and Google’s parental control settings can block purchases.
6. Coins, gems and in-game items
Coins, gems, hint tokens, stars and skins only have value within the game. They cannot be exchanged for money, transferred to another player or refunded. They are saved on your phone and disappear if you uninstall the game or clear its data; “Restore purchases” lets you recover purchases made with your Apple or Google account.
7. VIP codes
A VIP code is personal and can only be used once, on a single phone. It may not be sold or exchanged. A code that has been shared or obtained fraudulently may be refused.
8. Changes to the game
SUNDER DEV may change the game: levels, modes, balancing, in-game prices and skins. Some settings may be adjusted remotely, without an update. These terms may change; the date of the latest update appears at the top of this page.
9. Intellectual property
The game, its graphics, sounds, texts and code belong to SUNDER DEV or its licensors. You receive a personal, non-exclusive and non-transferable right to play Cubix, without the right to copy, modify or resell it. Cubix is neither affiliated with nor endorsed by the rights holders of Rubik’s Cube.
10. Liability
SUNDER DEV provides the game with care but cannot guarantee that it will run without interruption or error on every device. Nothing in these terms limits the rights you have under the law as a consumer, in particular the legal guarantee of conformity for digital content.
11. Personal data
The data processed by the game is described in the privacy policy.
12. Governing law and disputes
These terms are governed by French law. If you run into a problem, first write to contact@sunderdev.com: we will look for an amicable solution. A consumer may also use a consumer mediator free of charge.
