Terms of Use

We grant you a personal, limited, non-exclusive, non-transferable, revocable licence to download and use the App for your own non-commercial entertainment on Apple devices that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions.

You may not copy, modify, translate, rent, lease, lend, sell, redistribute or sublicense the App; decompile, reverse engineer or disassemble it or attempt to derive its source code (except where the law expressly allows this despite this restriction); or remove any proprietary notices. The App is licensed, not sold, and we and our licensors keep all rights not expressly granted to you.

The App features Hong Kong mahjong, a traditional tile game, and contains simulated gambling themes. You must be at least 17 years old (or the minimum age shown for the App on the App Store in your country, if higher) to use it. If you are under the age of majority where you live, you may use the App only with the involvement and consent of a parent or guardian, who agrees to these Terms on your behalf.

You may not use the App if you are barred from doing so under applicable law, or if we have previously suspended or terminated your access.

You can play solo without an account. Your local profile (display name and avatar), settings, saved games, statistics and replays are stored on your device.

The first time you use online play, the App creates a guest account on our game server from your local profile. The account is identified by a random account ID and a sign-in token kept in your device's keychain. If you delete the App or lose your device without linking a sign-in method, you may lose access to your guest account.

You may link Sign in with Apple or Google to your account so you can use it on other devices. Those sign-ins are provided by their respective companies under their own terms; we never receive your password.

You are responsible for activity on your account and for keeping your devices and sign-in methods secure. Accounts are personal: you may not sell, share or transfer your account, or use another person's account. Tell us promptly at support@mahjonghouse.app if you believe your account has been used without permission.

Your display name and avatar are shown to other players in online matches and on leaderboards. Display names must be unique and must not:

• be offensive, hateful, sexually explicit, threatening or harassing;
• impersonate another person, the App's club characters, ADM or its staff;
• contain personal information such as phone numbers, email addresses or real addresses; or
• promote gambling, other services or illegal activity, or infringe anyone's rights.

We may review, change, reset or remove any display name, and may restrict online features for accounts that break these rules, with or without notice.

We want every table to be fair. You agree not to:

• use cheats, bots, scripts, automation, modified clients or any software that plays for you or gives you information the App does not show you;
• collude with other players, share information about hands during a match, or deliberately lose, disconnect or abandon matches to manipulate season scores or leaderboards;
• create or use multiple accounts to manipulate matchmaking, season scores or leaderboards;
• exploit bugs, glitches or errors, instead of reporting them to us;
• attack, overload, probe, scrape or interfere with our servers, networks or other players' use of the App, or access any part of our systems you are not authorised to access;
• harass, threaten or abuse other players, or use the App for any unlawful purpose.

If we reasonably believe you have broken these rules, we may, at our discretion and to the extent permitted by law, cancel or adjust match results, reset or remove season scores and leaderboard positions, and suspend or terminate your account or access to online play.

Online play requires an internet connection and depends on our servers and third-party providers. We do not guarantee that online play will be available at any particular time or location, or free from interruptions, lag or errors.

When a table does not fill with players, computer-controlled club players take the empty seats. Matches have time limits for each decision. If you disconnect or run out of time, your seat is played automatically by default until you return, and the match continues. Results recorded by our server are final, except where we correct errors or act under section 5.

Ranked play uses season scores and seasonal leaderboards. We may change how season scores, seasons, matchmaking and rules work, and may reset season scores or leaderboards (for example at the start of a new season).

Scores in the App are counted in jade (玉), a points unit used only to keep score. Jade, season scores, leaderboard positions and any other in-game points or rankings have no monetary value. They cannot be purchased, sold, transferred, redeemed, withdrawn or exchanged for money, goods, services or anything of value, inside or outside the App.

The App does not offer real-money gambling or any opportunity to win money or prizes. Playing the App does not imply future success at real-money gambling. If gambling is causing you or someone you know harm, please contact a local support service.

You must not use the App, or any account, score or ranking in it, for betting, wagering or any exchange of value with anyone.

The App is free to download and play. It offers the following optional in-app purchases, which are sold and billed by Apple through the App Store and are subject to Apple's terms and payment policies. Prices below are US prices; the App Store shows the price in your currency before you buy, and prices may vary by country and include any applicable taxes.

• Remove Ads ($6.99, one-time, non-consumable): permanently removes advertising from the App for the Apple ID that bought it, and may be shared with your Family Sharing group. It does not unlock any other features.
• Sifu (師傅) coaching subscription ($3.99 per month or $29.99 per year, auto-renewing): coaching features in solo play (such as recommended discards with reasons, danger indicators, claim advice, faan route guidance, wait information and post-hand reviews), a review after online matches, and no ads while the subscription is active. Sifu gives no live hints in online matches. Sifu is not shared through Family Sharing.

Subscription terms. Payment is charged to your Apple ID account when you confirm the purchase. Your subscription renews automatically for the same period and at the then-current price unless auto-renew is turned off at least 24 hours before the end of the current period. Your account is charged for renewal within the 24 hours before the end of the current period. You can manage or cancel your subscription in your Apple ID account settings (Settings > your name > Subscriptions) at any time; cancellation takes effect at the end of the current paid period, and you keep access until then. There is no free trial. If we change the price of a subscription, Apple will notify you in advance as required, and you may cancel before the change takes effect.

Refunds. All purchases are processed by Apple, and we cannot issue refunds ourselves. Except where required by law, payments are non-refundable and there are no refunds or credits for partially used subscription periods. You may request a refund from Apple at reportaproblem.apple.com; Apple decides refund requests under its own policies.

Restoring purchases. If you reinstall the App or use another device signed in with the same Apple ID, use Restore Purchases in the App's Settings.

We may change, add or remove features of paid products, provided that the core benefit you paid for (no ads for Remove Ads; coaching in solo play for Sifu) remains for as long as we offer the App, and subject to your rights under applicable consumer law.

Unless you have bought Remove Ads or have an active Sifu subscription, the App shows advertisements between rounds of solo play. Ads are provided by third parties such as Google AdMob. We are not responsible for the content of third-party ads or for the products, services or websites they promote, and your dealings with advertisers are solely between you and them. How advertising uses data, and your consent choices, are described in our Privacy Policy.

The App and all of its content, including its code, design, artwork, characters, tile art, text, sounds and trademarks, are owned by ADM or its licensors and are protected by intellectual-property laws. The App's name as styled, its logo and its characters are brand assets of ADM. Mahjong itself is a traditional game; nothing in these Terms claims ownership of its rules.

If you send us ideas, suggestions or other feedback, you allow us to use them freely without any obligation to you.

The App relies on third-party services, including Apple (App Store, in-app purchases and Sign in with Apple), Google (AdMob advertising, consent management, Firebase Analytics and Google sign-in), RevenueCat (purchase management), Supabase (database and sign-in) and Railway (game server hosting). Your use of third-party sign-ins and services is also subject to those providers' own terms and privacy policies. We are not responsible for third-party services we do not control.

We may update, change, suspend or discontinue the App or any part of it (including online play, seasons, characters or features) at any time. Some updates may be required to keep using the App or its online features. Where a change materially reduces a paid feature you have bought, we will act in line with applicable consumer law.

To the fullest extent permitted by law, the App is provided "as is" and "as available", without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, title and non-infringement. We do not warrant that the App will be uninterrupted, error-free or secure, that defects will be corrected, or that any coaching, hints or analysis are correct or will improve your results. Mahjong rules and scoring vary by house and region; the App follows the rules it describes.

Some jurisdictions do not allow the exclusion of certain warranties, so some of these exclusions may not apply to you. Nothing in these Terms limits any rights you have as a consumer that cannot be limited by contract.

To the fullest extent permitted by law, ADM and its affiliates, officers, employees and licensors will not be liable for any indirect, incidental, special, consequential, exemplary or punitive damages, or for any loss of profits, revenue, data, goodwill, in-game progress, season scores or rankings, arising out of or related to the App or these Terms, even if we have been advised of the possibility of such damages.

To the fullest extent permitted by law, our total liability for all claims arising out of or related to the App or these Terms is limited to the greater of (a) the amount you paid for in-app purchases in the App in the 12 months before the event giving rise to the claim, and (b) US$50.

These limitations do not apply to liability that cannot be excluded or limited by law, such as liability for death or personal injury caused by negligence, or for fraud.

To the extent permitted by law, you agree to indemnify and hold ADM harmless from claims, losses and expenses (including reasonable legal fees) arising from your breach of these Terms or your misuse of the App.

You may stop using the App at any time and may ask us to delete your online account (see our Privacy Policy). We may suspend or terminate your access to the App or its online features if you materially or repeatedly breach these Terms, if required by law, or if we discontinue the App. On termination, your licence ends and you must stop using the App. Sections 7, 10 and 13 to 19 survive termination. Termination does not by itself entitle you to a refund; refunds are handled by Apple as described in section 8.

These Terms and any dispute arising out of or related to them or the App are governed by the laws of the State of California, USA, without regard to its conflict-of-law rules. The courts of the State of California, USA have exclusive jurisdiction, except that if you are a consumer you may also bring proceedings in the courts where you live, and you keep the protection of any mandatory consumer laws of your country of residence.

Before starting any formal proceedings, please contact us at support@mahjonghouse.app so we can try to resolve the issue informally.

If you downloaded the App from Apple's App Store, the following also applies:

• These Terms are between you and ADM only, not Apple Inc. ("Apple"). ADM, not Apple, is solely responsible for the App and its content.
• Your licence to use the App is limited to use on Apple-branded products that you own or control and as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, except that the App may be accessed by other accounts associated with you through Family Sharing or volume purchasing, where applicable.
• Apple has no obligation to provide any maintenance or support services for the App. Support is provided by ADM (see section 20).
• If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the App to you. To the maximum extent permitted by law, Apple has no other warranty obligation for the App, and any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to a warranty are ADM's responsibility, to the extent not excluded by these Terms.
• ADM, not Apple, is responsible for addressing any claims by you or a third party relating to the App or your possession or use of it, including product liability claims, claims that the App fails to conform to any legal or regulatory requirement, and claims under consumer protection, privacy or similar laws.
• If a third party claims that the App or your possession and use of it infringes that third party's intellectual-property rights, ADM, not Apple, is solely responsible for the investigation, defence, settlement and discharge of that claim.
• You represent and warrant that you are not located in a country subject to a U.S. Government embargo or designated by the U.S. Government as a "terrorist supporting" country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
• You must comply with applicable third-party terms (for example, your wireless data service agreement) when using the App.
• Apple and its subsidiaries are third-party beneficiaries of these Terms, and on your acceptance of these Terms Apple will have the right (and will be deemed to have accepted the right) to enforce them against you as a third-party beneficiary.

Where these Terms do not address a matter concerning your licence to the App, Apple's Licensed Application End User License Agreement (the Standard EULA) applies.

We may update these Terms from time to time. We will post the updated Terms on this page and change the effective date above, and where changes are material we will give reasonable notice (for example in the App). If you continue to use the App after the updated Terms take effect, you accept them. If you do not agree, stop using the App and, if you have one, cancel your subscription.

These Terms are written in English. Translations are provided for convenience; if there is any conflict, the English version governs. If any provision is found unenforceable, the rest remains in effect. Our failure to enforce a provision is not a waiver. These Terms, together with our Privacy Policy, are the entire agreement between you and us about the App.
