This Privacy Policy describes how GameStudioMJ ("we," "our," or "the Application") collects, uses, and discloses your information when you use our mobile game Ultimate Cards (the "Application").
By registering for and using the Application, you agree to the practices described in this policy.
1. Information We Collect
For the proper functioning of the game, we collect the following personal information:
Email Address: Used to create and manage your user account.
Password: Used to authenticate your access to the account. The password is encrypted and managed exclusively by Google Firebase authentication services.
Nickname: A username you choose upon registration. This nickname is necessary to identify your profile within the game, specifically to display it on the public leaderboard.
2. How We Use Your Information
We use the collected information solely for the following purposes:
To Create and Manage Your Account: To allow you to register and access the game.
User Authentication: To verify your identity each time you log in.
Game Functionality: To associate your progress and scores with your account and display them on the leaderboard under your nickname.
Account Recovery: To allow you to reset your password if you forget it, by sending a recovery link to your registered email address.
User Support: To identify you and assist you if you contact us with technical or support issues.
3. Legal Basis for Processing
The legal basis for processing your information is your consent by accepting this policy and the contract we establish with you upon registration to provide the game's services. The processing is necessary for the basic functioning of the Application.
4. Storage and Security of Information
All information described above (email, encrypted password, and nickname) is stored securely on Google Firebase servers, a Google Cloud platform. We implement technical and organizational security measures to protect your data against unauthorized access, disclosure, or destruction. However, no method of transmission over the Internet or electronic storage is 100% secure, therefore we cannot guarantee absolute security.
5. Disclosure of Your Information
We do not sell, trade, or otherwise transfer your personal information to third parties. Your information is used strictly for the internal purposes described in this policy.
The only information visible to other users of the application is your nickname, which appears on the game's leaderboard.
6. Your Rights
Depending on your location, you may have rights regarding your personal data, which include:
Access: You can request a copy of the personal information we hold about you.
Rectification: You can update or correct your information (such as your nickname) from within the application, if the functionality allows, or by contacting us.
Erasure (Right to be Forgotten): You can request the deletion of your account and all associated data.
Withdrawal of Consent: You can withdraw your consent for us to process your data, which may result in the deletion of your account.
To exercise any of these rights, please contact us at: gamestudiomj@gmail.com
7. Login and Logout
You can log in and out of your account as many times as you wish. Each login requires authentication through Firebase to ensure the security of your account.
8. Password Recovery
If you forget your password, the Application offers a "Reset Password" function. Using this function will send a secure link to your registered email address, allowing you to set a new password. This process is managed entirely by Firebase Auth.
9. Third-Party Service Providers
We use the following third-party service providers that may have access to your information, but only to perform tasks on our behalf and are obligated not to disclose or use it for any other purpose:
Google Firebase: We use Firebase for user authentication and as a real-time database. You can review Google's privacy policy here: https://policies.google.com/privacy
