Privacy Policy

Last updated: September 12, 2026

Twenty Nine ("the app") is developed by Rannabanna ("we", "us"). This page explains what information the app collects, why, and how you can control it. It applies to the Twenty Nine mobile app on Android and iOS.

Information we collect

Account information. If you sign in with Google or Apple, we receive your name, email address, a profile photo (if you have one), and a unique account identifier from that provider. We use this to let you keep the same account, match history, and rating across devices.
Gameplay data. Match results, ratings, and room/lobby activity are stored on our game servers, tied to your account, so your match history and leaderboard standing are available the next time you play.
Crash and error reports. We use Sentry to automatically capture crash reports and errors — this can include your device model, OS version, and a technical stack trace of what the app was doing when it failed. It does not include your card hand, chat, or other gameplay content.
Advertising data. The app shows ads through Google AdMob (and, if enabled, its mediation partners) to help fund development. Depending on your region and your own choices, these networks may use a device advertising identifier to show either personalized or non-personalized ads. In the EEA/UK, we ask for your consent before any ad-related data collection through a standard consent form; on iOS, the system's own App Tracking Transparency prompt asks separately for tracking permission. You can review or change your ad consent choice at any time from Settings → Ads Privacy Options inside the app, where that option is shown.
Local network access. "Play with Friends" uses your device's local network (Wi-Fi) to host or join a game with nearby players. This traffic stays on your local network and is never sent to us.

How we use this information

To let you sign in and keep your progress across devices, to run online and local multiplayer matches, to diagnose and fix crashes, and to show ads that help cover the cost of running the game's servers. We do not sell your personal information.

Your choices

You can sign out at any time from the Account screen.
You can change or withdraw your ad consent at any time from Settings → Ads Privacy Options (where shown), or from your device's own ad personalization settings.
To request deletion of your account and associated data, email us at mainul.hasan.shuvro@gmail.com.

Children's privacy

Twenty Nine is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, contact us and we will delete it.

Changes to this policy

We may update this policy from time to time. Changes will be posted on this page with an updated date at the top.
