1. Scope
These terms apply to the use and purchase of digital content in "Katana Inu: Samurai Task Force" (STF) and on this website. The provider is Chainvision Games FZCO, Dubai (see legal notice). The game is free to play.
2. Which data we collect
The current game links a player name, save and verified leaderboard data to a device account. Bug reports contain the submitted text, an optional screenshot, version and platform details. The next game release will add in-game registration and collect the player name and email address for the account, save and leaderboard assignment, and support or necessary account contact (Art. 6(1)(b) GDPR). Marketing email requires a separate double-opt-in consent (Art. 6(1)(a) GDPR), can be unsubscribed from at any time and is never required to play. Account data is kept while the account is active and afterwards only where required; bug reports are deleted after 90 days. Deletion may be requested at the address in the legal notice. Details are in the Privacy Policy.
3. Voluntary digital purchases
The following are available as optional in-game purchases: Founder Pack, Hero Packs, Storage+, skins, backdrops, soundtrack, Supporter and the Complete Bundle. There is no pay-to-win, no loot boxes and no real-money currency. The content is digital goods with no cash value; it grants only a personal, non-transferable licence for STF and is not an investment.
4. Prices and contract
Purchases are completed inside the game. All listed prices are final prices including statutory VAT. The final total is shown before payment; Stripe applies the correct tax treatment for the selected country. The contract is concluded when payment is accepted and the purchase is confirmed. Minors may only make purchases with the consent of their parent or legal guardian.
5. Payment
The in-game checkout offers card payment through Stripe and crypto invoices through NOWPayments. Crypto risks: blockchain payments normally cannot be reversed; follow the invoice amount, network, address and time limit exactly; the payer bears fees; a wrong detail can cause permanent loss. Crypto payment is not an investment and not financial advice.
6. Binding of the purchase, restore
A purchase is bound to a device or account through a proof of ownership signed by the server. It can be restored with a code or with a Katana Inu account (launcher). If you lose the device and code and use neither, you may lose access; on request we help after checking the purchase receipt.
7. Right of withdrawal and digital content
Consumers in the EU generally have a 14-day right of withdrawal. For digital content not supplied on a tangible medium, it expires once performance begins if you gave prior express consent to immediate performance, acknowledged that you thereby lose your right of withdrawal, and we confirmed the contract on a durable medium (§ 356(5) BGB). We obtain this consent and acknowledgement before purchase.
Withdrawal information
You have the right to withdraw from this contract within 14 days without giving any reason. The withdrawal period is 14 days from the day the contract is concluded. To exercise the right of withdrawal, you must inform us (Chainvision Games FZCO, Dubai Silicon Oasis, Dubai Digital Park, Building A1, P.O. Box 342 001, Dubai, United Arab Emirates; business@katanainu.com) of your decision by a clear statement. You may use the model form below, but it is not mandatory. To meet the deadline, it is sufficient to send your communication before the period expires.
Effects of withdrawal: if you validly withdraw, we reimburse the payment without undue delay and no later than 14 days after receiving your notice, using the same payment method unless agreed otherwise.

8. Statutory warranty and refunds
The statutory warranty for digital products applies (for consumers under §§ 327 et seq. BGB): we supply the content in conformity with the contract and keep it working while it is supplied, including necessary updates. If there is a defect, you may request that it be remedied and, if this fails, reduce the price or terminate the contract.
Beyond the statutory right of withdrawal and statutory defect and consumer rights, we do not refund voluntarily. Mandatory consumer rights remain unaffected.
9. Holder benefits
Holder benefits ($KATA discount, NFT skins) apply only in the Katana Inu version of STF, not on Steam and not in the App Store. They are not a return, not a promise of value and not financial advice.
10. Fair play
Cheating, manipulating game values or replays, abusing the leaderboard and using another person's payment method without permission are prohibited. For serious breaches we may remove leaderboard entries or block access.
11. Governing law
German law applies, without depriving consumers of the mandatory protection of their country of residence.
