Terms of Service
Last updated: November 2026
These Terms of Service (these “Terms”) are an agreement between Commerce Street Gaming, Inc., a Texas corporation doing business as The Mahj Room (“The Mahj Room,” “we,” “us,” or “our”), and you. They govern your access to and use of our American Mahjong application and related content, tile designs, features, and services at themahjroom.app and in any Mahj Room app (collectively, the “Service”).
By creating an account or using the Service, you agree to be bound by these Terms and acknowledge our Privacy Policy. Please read them carefully and keep a copy. If you do not agree, do not use the Service.
Company: Commerce Street Gaming, Inc. (a Texas corporation) d/b/a The Mahj Room. Address: 2100 Elton Ln., Austin, TX 78703. Contact: [email protected].
1. Eligibility and Your Account.
You must be at least 18 years of age to use the Service. Your account is personal to you. You may not share your account or login credentials with, or allow use of the Service by, any other person. You are responsible for activity on your account, and you agree to tell us promptly at [email protected] if you believe someone else has used it. We may limit, suspend, or revoke access at any time if we believe you have violated these Terms. You may delete your account at any time from your account settings; deleting your account does not cancel a paid membership, so cancel first as described in Section 3.
2. License to Use the Service.
Subject to these Terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Service solely for your own personal, non-commercial entertainment and learning. The Service is licensed, not sold, to you. All rights not expressly granted are reserved to us and our licensors.
3. Membership, Trial, Billing, and Cancellation.
Playing The Mahj Room is a monthly membership. The free trial, current prices, monthly billing, how to cancel, and refunds are set out in our Cancellation & Refund Policy, which is part of these Terms. Prices do not include sales tax, which is added where applicable. If the price of your membership changes, we will tell you before the new price applies to you, and you may cancel before it takes effect. If you subscribe through the Apple App Store or Google Play, that store bills you and handles cancellation and refunds under its own terms.
4. The Game.
The Service is a social and skill game, for entertainment and learning only. It does not offer real-money wagering, betting, prizes, or cash payouts. Points, scores, settlements, achievements, and other in-game features have no cash value and cannot be redeemed or exchanged for money. American Mahjong is played under different house rules and card editions; our rules, hints, coaching, and scoring may differ from the practices of your group, teacher, or club. The Mahj Room is not affiliated with, sponsored by, or endorsed by the National Mah Jongg League, and you are responsible for having your own copy of any card you play.
5. Ownership and Intellectual Property.
All right, title, and interest in and to the Service and all related intellectual property — including the application, software, tile designs (including our patent-pending stripe-bearing tile designs, U.S. Design Patent Application Serial No. 30/071,987), artwork, graphics, lessons, narration, trademarks, and any improvements, modifications, and enhancements — are and will remain owned by us and our licensors. Except for the limited license expressly granted in these Terms, no rights are granted to you, whether by implication, estoppel, or otherwise. “The Mahj Room” and our logos are our trademarks; you may not use them without our prior written consent. You may not reproduce, manufacture, sell, distribute, or create products from our tile designs or artwork.
You are welcome to take ordinary screenshots of your games to share with friends or to post about The Mahj Room, provided you do not remove our notices, misrepresent an affiliation with us, or use them commercially.
6. Feedback.
From time to time you may give us comments, suggestions, bug reports, or other feedback about the Service (“Feedback”). You agree that we may freely use all Feedback for any purpose, including to improve our products and services, without restriction, attribution, or compensation to you. You hereby assign to us all right, title, and interest in and to your Feedback. To the extent that assignment is not effective, you grant us a perpetual, irrevocable, worldwide, royalty-free, sublicensable, and transferable license to use, reproduce, modify, and otherwise exploit the Feedback without restriction.
7. Your Data.
You retain ownership of the information you provide to us through the Service (“Your Data”). You grant us a worldwide, non-exclusive license to use Your Data to: (a) operate and provide the Service to you; (b) monitor, test, and improve the Service; and (c) create and use aggregated or de-identified data that does not identify you, for any purpose. Our handling of personal information is described in our Privacy Policy, which is incorporated into these Terms by reference. When you play with others, the name you play under and your moves at the table are visible to the other players at that table.
8. Acceptable Use.
You agree that you will not, and will not attempt to: (a) rent, lease, lend, sell, sublicense, or otherwise transfer or make the Service available to any third party; (b) copy, modify, translate, or create derivative works of the Service; (c) decompile, disassemble, reverse engineer, or attempt to derive the source code of the Service, except to the limited extent this restriction is prohibited by applicable law; (d) remove, obscure, or alter any proprietary notices; (e) access or use the Service to build a competing product or to copy its features or designs; (f) introduce any malware or attempt to gain unauthorized access to, disrupt, or place an unreasonable burden on the Service or its systems; (g) cheat, use bots or scripts, or create multiple accounts to manipulate games, achievements, or membership benefits; (h) harass other players or choose an offensive name; or (i) use the Service in violation of any applicable law or the rights of any third party.
9. Term and Termination.
These Terms take effect when you first use the Service and continue until terminated. You may stop using the Service, cancel your membership, or delete your account at any time. We may suspend or terminate your access to the Service if we believe you have violated these Terms, and we may remove or delete Your Data when your account is deleted. Upon termination, the license granted to you ends and you must stop using the Service. Sections 5 through 14 survive termination.
10. Changes to the Service and These Terms.
Features may be added, modified, or removed. We may update these Terms; the current version is always posted at this page with the date it was last updated, and your continued use of the Service after an update means you accept the updated Terms.
11. Disclaimer of Warranties.
THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTY OF ANY KIND, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE. TO THE FULLEST EXTENT PERMITTED BY LAW, WE SPECIFICALLY DISCLAIM ALL IMPLIED WARRANTIES, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY OF DATA, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE, OR THAT OUR RULES, HINTS, OR SCORING WILL MATCH THE RULINGS OF ANY THIRD-PARTY ORGANIZATION.
12. Limitation of Liability.
TO THE FULLEST EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICE IN THE TWELVE MONTHS BEFORE THE CLAIM AROSE OR (B) FIFTY U.S. DOLLARS (US$50). IN NO EVENT WILL WE BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST PROFITS, LOST DATA, OR LOSS OF USE), EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. THESE LIMITATIONS APPLY NOTWITHSTANDING ANY FAILURE OF ESSENTIAL PURPOSE OF ANY LIMITED REMEDY.
13. Governing Law and Venue.
These Terms are governed by the laws of the State of Texas, without regard to its conflict-of-laws principles. You agree that the exclusive venue for any dispute arising out of or relating to these Terms or the Service will be the state and federal courts located in Travis County, Texas, and you consent to the personal jurisdiction of those courts.
14. General.
These Terms, with the Privacy Policy and the Cancellation & Refund Policy, are the entire agreement between you and us regarding the Service and supersede any prior understandings on that subject, including any beta test agreement. You may not assign these Terms without our prior written consent; we may assign them freely. Our failure to enforce any provision is not a waiver. If any provision is held unenforceable, the remaining provisions remain in full force and effect. You agree to comply with all applicable U.S. and foreign export-control laws in connection with the Service. If you obtain the app from the Apple App Store or Google Play, that store’s standard end-user terms also apply, these Terms are between you and us and not the store, and the store is not responsible for the app or for any support or warranty claims about it.
