Privacy Policy

This Privacy Policy explains how Commerce Street Gaming, Inc., doing business as The Mahj Room (“we,” “us,” or “our”), handles information when you use our American Mahjong application and website at themahjroom.app and in any Mahj Room app (the “Service”). We try to collect as little information as we need to run the game and your membership. This Policy is part of our Terms of Service.

1. Information We Collect

(a) Waitlist. If you join our waitlist, your email address is kept with Kit, the email service we use to send our updates. (b) Account information — your email address and the name you play under, and your full name if you choose to give it. Sign-in is handled by Clerk, which sends a code to your email; we do not store a password. (c) Membership and payment information — payments are processed by Stripe, and your card details go directly to Stripe. We never see or store your full card number. Stripe shares with us whether your subscription is active, your plan, and your billing address, which we use to calculate sales tax. (d) Gameplay and app-activity information — your settings, lesson and practice progress, the hands you have won and achievements you have earned, the last room you were in, and the moves of the games you play, so the game can run and your progress follows your account. (e) Device and technical information — information such as device type, browser, operating system, app version, IP address, and diagnostic logs, recorded by the services that host the game. (f) Feedback — any comments, bug reports, or suggestions you choose to send us, along with the screen you were on, the app version, a snapshot of the game at that moment, and a screenshot if you attach one.

We use Cloudflare Web Analytics to understand how visitors use our websites. It collects limited, aggregated information (such as pages visited, referring sites, and general location and device type) and does not use cookies or track you across other websites.

We do not ask for your contacts, your location, or access to your camera or microphone. We do not use advertising networks or track you across other companies’ apps or websites.

2. How We Use Information

We use the information we collect to: provide and operate the Service; create and manage your account and membership, and calculate sales tax where it applies; identify and fix bugs; test, measure, and improve features and designs; respond to your feedback and questions; send you updates about the Service, which you can unsubscribe from at any time using the link in any email we send; and protect the security and integrity of the Service and our intellectual property. We may also create aggregated or de-identified information that does not identify you and use it for any purpose.

3. How We Share Information

We do not sell your personal information. We may share information only: (a) with service providers who help us operate the Service and who are permitted to use it only to provide services to us — Cloudflare, which hosts the game; Neon, which stores its data; Clerk, which handles sign-in; Stripe, which processes payments; and Kit, which sends our emails; (b) with the other players at your table, who can see the name you play under and your moves in that game; (c) if required by law or to protect our rights, safety, or property; and (d) in connection with a business transfer such as a merger or acquisition.

4. Cookies and Local Storage

The Service uses cookies and your browser’s local storage to keep you signed in and to remember your settings. We do not use advertising cookies.

5. Data Retention

We keep your account and gameplay information for as long as you have an account. When you delete your account, your account and gameplay records are removed from our database, and copies in backups age out over the following weeks. We keep billing records for as long as tax and accounting law requires, and we may keep feedback you have sent us. A record that an account existed and was deleted remains, without your details. Otherwise we keep information only as long as needed for the purposes described in this Policy, unless we are required to keep it longer by law.

6. Security

We take reasonable measures to protect the information we hold, including encrypted connections and limits on who can access it. However, no method of transmission or storage is completely secure, and we cannot guarantee the security of any information.

7. Your Choices and Rights

You can update your name and email address in your account settings. You can delete your account from your account settings, or by contacting us. You may contact us at any time to ask what information we hold about you, or to request a correction or deletion. Depending on where you live, you may have additional rights under applicable privacy laws. To exercise any of these, contact us using the details below.

8. Children

The Service is intended only for adults who are at least 18 years old. It is not directed to children, and we do not knowingly collect information from anyone under 18. If you believe a minor has provided information to us, please contact us so we can delete it.

9. Where Information Is Stored

The Service is operated from the United States, and your information is stored there and wherever our service providers operate.

10. Changes to This Policy

We may update this Policy. If we make material changes, we will take reasonable steps to let you know. The “last updated” date above shows when this Policy was last revised.
