Terms of use

Draft for review: this text has not been approved yet.

Last updated: November 9, 2026

These terms govern your use of the mobile game Cristalune (the "Game") and of this website. By installing or using the Game, you accept them.

1. Publisher

ASURA STUDIO, SARL with a capital of €100, 1 Cours du Buisson, 77186 Noisiel, France, SIREN 994 847 358. Contact: contact@asura.studio.

2. License

We grant you a personal, non-exclusive, non-transferable and revocable license to use the Game for private, non-commercial purposes.

3. Account

The Game creates an account tied to your device. Until it is linked to an Apple or Google account, losing it (new device, game erased) may mean losing your heroes. In Settings > Account, you can link it to an Apple or Google account to recover it on another device; we then keep only an opaque identifier, no email or name. A linked account remains your responsibility: do not share it.

4. Online game

The Game needs an Internet connection. We may update it, change its content or balance, suspend it for maintenance or stop running it. In case of permanent closure, we will give you 30 days' notice, in the Game and on this website.

5. Purchases and Moons

• The Game is free to download. It offers optional in-app purchases (Moons, for cosmetic items only).
• The seller is ASURA STUDIO (see section 1). Prices, taxes included, are displayed by Apple or Google before purchase, in your currency.
• You buy "Moons", the Game's virtual currency, used to obtain cosmetic items. Nothing the shop sells gives power in the Game.
• A Moon is a limited, personal, non-transferable right of use, valid in the Game only. It has no value outside the Game: no exchange, no resale, and no refund in money from us.
• Gold and items likewise have no monetary value: they cannot be refunded, except as required by law, or exchanged for money.
• Purchases are made and paid for through Apple or Google, under their terms; ask them for refunds.
• If Apple or Google refunds a purchase, we take back the corresponding Moons, and we may close purchases on an account that repeatedly requests refunds.
• Purchased content is delivered immediately. By requesting it, you agree that delivery starts at once and acknowledge that you lose your right of withdrawal.

6. Auction House

The Auction House lets you trade items for in-Game gold only, with a tax in gold. Selling, buying or trading items, gold or accounts for real money outside the Game is forbidden.

7. Rules of conduct

You agree not to cheat, use bots, modify or decompile the Game (except where the law allows it) or exploit its bugs. Names that are insulting, hateful, sexual or that impersonate someone are forbidden. Depending on severity, we may rename a hero, remove a leaderboard entry or suspend an account. You can contest a decision at contact@asura.studio.

8. Deletion

You can delete your account at any time. This is permanent, including for what you bought.

9. Liability

The Game is provided as is. To the extent permitted by law, we are not liable for indirect damages or for interruptions caused by your device or connection. Nothing here limits your consumer rights.

10. Personal data

See the privacy policy.

11. Minors

The Game is intended for people aged 13 and over. Minors play with the consent of their parents or legal guardians, who can manage purchases with Apple or Google parental controls. We do not seek to push a player into buying: the real price is always displayed.

12. Governing law

These terms are governed by French law. If there is a dispute, please contact us first. [À COMPLÉTER : consumer mediator.] Failing agreement, the competent courts are those provided for by law.
