These Terms of Use govern the “Mahjong” app (the “App”) on iPhone, iPad, Mac, Apple TV and Apple Vision Pro. By downloading and using the App you agree to these terms. Your agreement is with me, not with Apple.
2. The App and the Full Version
The App is a mahjong solitaire game. A large part of the levels is permanently free to play, with no ads and no time limits.
A one-time in-app purchase (the “Full Version”) additionally unlocks all levels, all tile designs, and the complete daily puzzle archive. It is a single purchase, not a subscription. There are no recurring charges.
- The purchase is processed entirely through your Apple account. Apple shows you the price and payment details before you buy.
- The Full Version is tied to your Apple account and can be restored free of charge at any time on all your devices and after reinstalling, using “Restore Purchases” on the purchase screen.
- The Full Version supports Apple Family Sharing: members of your Apple family group can use it without buying again.
- The purchase contract for the full version is not concluded with me but with Apple Distribution International Ltd., Hollyhill Industrial Estate, Hollyhill, Cork, Ireland. Price, payment, refunds and any statutory right of withdrawal are therefore governed by Apple's terms and must be asserted against Apple. Refunds can be requested at reportaproblem.apple.com. Your statutory rights against Apple remain unaffected.
3. License
You are granted a non-exclusive, non-transferable license to use the App on Apple devices that you own or control, for private, non-commercial purposes, as permitted by the Usage Rules in Apple's Media Services Terms and Conditions.
You may not copy, modify, decompile, reverse engineer, sell, rent, or otherwise make the App available to third parties outside Family Sharing. All rights in the App, its content and its trademarks remain with me.
4. Optional Services
Game Center (leaderboards, achievements), iCloud sync, and challenge links are optional features. They require the corresponding Apple services and an internet connection. The game itself works fully offline. I do not guarantee uninterrupted availability of these Apple services.
5. Availability, Maintenance, and Support
I strive to keep the App free of defects and to update it regularly. I provide the updates necessary to maintain the conformity of the App, including security updates; there is no entitlement to any particular further features. I alone, not Apple, am responsible for maintenance and support. Please direct support requests to joe@waldow.app or via https://waldow.app.
6. Liability
I am liable without limitation for intent and gross negligence and for injury to life, body or health, and to the extent of any guarantee I have given. In cases of simple negligence I am liable only for the breach of a material contractual obligation. Material contractual obligations are those obligations whose fulfilment makes achieving the purpose of the contract possible in the first place, on whose observance you may therefore rely, and whose breach endangers the achievement of the purpose of the contract. In such cases my liability is limited to the foreseeable damage typical for this type of contract at the time the contract was concluded. Liability under mandatory product liability law remains unaffected. Your statutory rights in respect of defects in the app, and your rights against Apple, are not restricted by this section.
7. Apple's Role
This agreement is between you and me, not with Apple. Apple has no warranty or other obligation with respect to the App and is not responsible for any claims relating to it (such as product liability, legal defects, or consumer protection claims). However, Apple and its subsidiaries are third-party beneficiaries of these Terms of Use and may enforce them against you. In the event of any third-party claim that the App infringes intellectual property rights, I alone am responsible for the investigation, defense, and resolution.
You represent that you are not located in a country subject to a U.S. government embargo and that you are not on any U.S. government list of prohibited or restricted parties.
8. Changes to These Terms
I may amend these terms with effect for the future, for example for new features or changes in the law. The current version is always available at https://waldow.app/terms-mahjong. Material changes will be announced in the App or in the update notes.
9. Final Provisions
German law applies. As a consumer, you additionally enjoy the protection of the mandatory provisions of the law of your place of habitual residence. Should individual provisions be invalid, the validity of the remaining provisions remains unaffected.
Privacy note: How the App handles data is described in the privacy policy at https://waldow.app/privacy-mahjong.
