Privacy Policy

Effective: April 2026

Hey there! Thanks for being part of Mahjong Mamas Social Club. We take your privacy seriously, and we promise to keep this short, sweet, and free of legalese.

About the App

Mahjong Mamas Social Club is a social club app for mahjong groups. Users join clubs, RSVP to game nights, chat with other members, and manage their profile. It's built for real people who play mahjong together, not a data-harvesting machine.

What We Collect

When you use the app, we may collect the following:

• Email address: used to create your account and reach you if needed
• Display name: so your club members know who's sitting at the table
• Profile photo (optional, user-uploaded): add a face to the name, if you'd like
• Push notification token: used to send you game reminders
• Calendar event data: when you add a game to your calendar, we write it to your device calendar only. We do not store calendar data on our servers.

Why We Collect It

We use your info to create and manage your account, identify you to your fellow club members, and send you notifications about upcoming games and waitlist updates. That's it. No funny business.

Permissions We Use

The app may request the following permissions on your device:

• Photo library: lets you upload a profile avatar
• Calendar: adds game events to your device calendar (we don't read your calendar)
• Push notifications: sends you game reminders and waitlist updates

Each permission is optional and only used for the purpose described. You can manage these any time in your device's Settings.

Third-Party Services

We use a small number of trusted third-party services to run the app. Here's who they are and what they do:

• Supabase: database hosting and authentication (US-based, hosted on AWS)
• Google Firebase: analytics and push notifications for Android
• Google Sign-In: authentication, when chosen by the user
• Sign in with Apple: authentication, when chosen by the user

When you use Google Sign-In or Sign in with Apple, their own privacy policies apply to that authentication flow. We only receive the basic profile info needed to create your account.

Push Notifications

We send push notifications through Expo, Apple Push Notification service (APNs), and Google Firebase Cloud Messaging (FCM) to let you know about game reminders, waitlist updates, and other club activity. You can turn these off any time in your phone's Settings app.

Do We Share Your Data?

Nope. We do not sell, rent, or share your personal data with third parties. Your info stays between you, your club, and us. The third-party services listed above only process data as needed to provide the app's functionality.

Data Retention

We store your data for as long as your account is active. If you delete your account, we'll remove all associated data from our systems.

Security

Your data is stored in encrypted cloud databases. We use industry-standard authentication and security practices to keep your information safe. While no system is 100% bulletproof, we take reasonable steps to protect what you've shared with us.

Deleting Your Account

Want out? No hard feelings. Send us an email at mahjongmamassupport@gmail.com and we'll delete your account and all associated data.
