These Terms of Use (“Terms”) form a binding agreement between you and SparkArk Studio, ul. Narutowicza 12b/2, 70-240 Szczecin, Poland (“we”, “us”), covering the mobile game Mahjong Room (“the Game”). By downloading, installing, opening or playing the Game you accept these Terms. If you do not accept them, do not install or play the Game.
Our Privacy Policy forms part of these Terms.
We grant you a personal, non-exclusive, non-transferable, non-sublicensable, revocable licence to install and play the Game on devices you own or control, for your own private, non-commercial entertainment.
The licence does not permit you to sell, rent, sublicense, distribute or publicly perform the Game for a fee; to modify, adapt, translate, decompile, disassemble or reverse engineer it, except to the extent that applicable law expressly permits it despite this restriction; to remove or alter any notices of ownership; or to use the Game to build a competing product.
The Game is intended for a general audience and is not directed to children. You must be at least 16 years old to play if you are in the European Economic Area, or at least 13 years old elsewhere. If you are below the age of majority where you live, you may play only with the consent of a parent or legal guardian, who is then responsible for your use of the Game.
The Game contains virtual items — hints, undos, shuffles, ejects, spins and similar boosters. Understand clearly that:
The Game currently offers no purchases for real money. Boosters are earned through play or granted for watching a rewarded advertisement. If paid items are introduced in a future version, they will be clearly marked, purchased through the app store you installed from, and governed by that store's refund policy alongside your statutory rights as a consumer.
The Game is free and funded by advertising. Two formats appear:
Advertisements are supplied by third parties. We do not control, endorse or take responsibility for their content, or for any product, service, offer or website they lead to. Any dealing you have with an advertiser is between you and that advertiser. Details of our advertising providers, and how to limit ad personalisation, are set out in Ad Partners & Advertising.
You agree not to:
Breaching this section may cost you access to leaderboards and achievements, or to the Game, without compensation.
All progress, boosters, streaks and settings are stored on your device only. There is no account and no cloud save.
This means your progress is permanently lost if you uninstall the Game, clear its data, reset your device, or switch to a different device. We hold no backup and cannot restore or transfer progress, and we are not liable for its loss. Where your device or app store offers its own backup feature, using it is your responsibility.
The Game and everything in it — code, artwork, tile designs, user interface, sound effects, music, text and the name “Mahjong Room” — is owned by us or licensed to us and is protected by copyright and other intellectual property laws. Nothing in these Terms transfers any of those rights to you. Third-party components are used under their respective licences; the Geologica typeface is used under the SIL Open Font License.
The traditional game of mahjong, and the traditional tile symbols it uses, are part of the public domain; our specific artwork, arrangement and implementation of them are not.
The Game uses services provided by Google (Firebase, AdMob, Google Play Games Services) and, on iOS, by Apple (Game Center). Your use of those services is also subject to their own terms and privacy policies. We are not responsible for their availability or their behaviour.
Your right to install and use the Game also depends on the terms of the app store you obtained it from. If those store terms conflict with these Terms in respect of the store's own obligations, the store terms prevail for that subject matter.
If you obtained the Game from the Apple App Store, the following applies and prevails over anything inconsistent elsewhere in these Terms:
We aim to keep the Game available and working, but we do not guarantee uninterrupted availability. We may update the Game to add, change or remove features, to fix defects, or to comply with the requirements of app stores or of the law. Some updates may be required in order to keep playing.
We may discontinue the Game or any of its features. Where we do so we will give reasonable notice inside the Game or on this site, unless circumstances outside our control prevent it. Virtual items are not compensated on discontinuation, since they have no monetary value (section 4).
To the extent permitted by law, and without affecting the statutory rights you have as a consumer, the Game is provided “as is” and “as available”. We do not warrant that it will be free of defects, that it will run on every device, that advertisements will always be available, or that any particular level, reward or difficulty will remain unchanged.
Nothing in this section limits the legal conformity guarantee that EU and other applicable consumer law gives you for digital content.
To the fullest extent permitted by applicable law, we are not liable for indirect or consequential loss, loss of profit, loss of opportunity, or loss of data or game progress, arising from your use of, or inability to use, the Game.
Where our liability cannot be excluded, it is limited to the amount you paid us for the Game in the twelve months before the event giving rise to the claim — which, for a free game, is normally zero.
Nothing in these Terms excludes or limits our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, for intentional misconduct or gross negligence, or for anything else that may not lawfully be excluded or limited — including your mandatory rights as a consumer.
You may end this agreement at any time by deleting the Game from your device. We may suspend or end your licence if you materially breach these Terms, in particular section 6. On termination, the licence in section 2 ends and you must stop using the Game; sections 8, 12, 13 and 16 survive.
We may amend these Terms where there is a valid reason — a change to the Game, to our providers, or to the law. The “last updated” date shows the current version, and material changes will be announced inside the Game before they take effect. If you do not accept the new Terms, your remedy is to stop playing and uninstall the Game.
These Terms are governed by the law of Poland, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods.
If you are a consumer, this choice of law does not deprive you of the protection of the mandatory provisions of the law of the country in which you habitually reside, and you may bring proceedings in the courts of that country. Consumers resident in the EU may also use the European Commission's online dispute resolution platform at ec.europa.eu/consumers/odr. We are not obliged, and do not undertake, to participate in proceedings before a consumer arbitration body.
If you are not a consumer, the courts of Warsaw, Poland have exclusive jurisdiction.
If any provision of these Terms is held invalid or unenforceable, the remainder stays in force and the invalid provision is replaced by the valid one closest to its intent.
