Terms of Use
Last updated: 29 July 2026
Apple’s Standard End User License Agreement applies in addition: apple.com/legal/internet-services/itunes/dev/stdeula
1. Scope
These terms govern the use of the Kreuzbube app (“the app”), provided by Kerem Karayağız. By downloading and using the app you agree to these terms.
2. Contractual partner for purchases
The app is distributed exclusively through the Apple App Store. Your contractual partner for acquiring the app and for all in-app purchases is Apple, not the developer. Apple’s terms apply to the purchase process, billing and refunds.
3. Licence
You receive a simple, non-exclusive, non-transferable right to use the app for private purposes on devices associated with your Apple Account. Reverse engineering, decompiling, modifying, renting, reselling or redistributing the app, as well as removing copyright notices, are not permitted.
4. Full version and one-time purchase
The app can be downloaded free of charge and used to a limited extent. The full version is unlocked through a one-time in-app purchase. This is expressly not a subscription: there are no recurring payments and nothing renews automatically. The purchase is tied to your Apple Account and can be reactivated on your devices via the “Restore purchases” function.
5. Withdrawal and refunds
Since Apple is your contractual partner, the right of withdrawal and refunds are governed by Apple’s terms. Please submit refund requests directly to Apple via reportaproblem.apple.com. The developer cannot issue refunds directly.
6. Rules of play
The app implements the International Skat Order. Deviations, optional house rules and the strength of the computer opponents are documented in the settings. There is no entitlement to any particular level of computer opponent strength.
7. Availability and updates
The app runs entirely offline; no server service is operated that could fail. The developer is not obliged to provide updates but endeavours to keep the app compatible with current iOS versions. Features may be added, changed or removed as part of updates.
8. Your data
You are responsible for your own game states and statistics. The developer stores no copy of your data and cannot restore lost game states. Details can be found in the privacy policy.
9. Warranty and liability
The developer is liable without limitation for intent and gross negligence and for damage arising from injury to life, body or health. In cases of simple negligence the developer is liable only for breach of a material contractual obligation whose fulfilment makes proper performance of the contract possible in the first place and on whose observance you may regularly rely; in such cases liability is limited to the foreseeable damage typical for this type of contract. Liability under product liability law remains unaffected. Statutory warranty rights are not restricted by these terms.
10. Changes to these terms
These terms may be amended, for example when new features are added or the legal situation changes. The current version is always available at this address.
11. Governing law
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. Mandatory consumer protection provisions of the country in which you have your habitual residence remain unaffected.
