CenterStack Privacy Policy
Last updated: August 17, 2026
CenterStack is developed and published by AAAnnagur Apps.
This Privacy Policy explains what information CenterStack processes, why it is used, how it is protected, and how users can request deletion of their account and associated data.
1. Information We Process
CenterStack does not require users to provide their real name, email address, phone number, or precise location in order to play.
The game may process the following information:
• Anonymous account identifier:
CenterStack uses Firebase Authentication to create an anonymous account. This generates a unique user identifier (UID) that allows online game features to work without requiring an email address or password.
• Player nickname:
Users choose a unique nickname for their CenterStack player profile.
• Gameplay and leaderboard information:
CenterStack may store information such as player nickname, score, placed block count, level, weekly leaderboard score, all-time leaderboard score, ranking information, and relevant timestamps.
• Weekly reward information:
Information related to leaderboard rewards may be stored in order to determine eligibility and prevent the same reward from being claimed more than once.
• Security and anti-abuse information:
CenterStack uses Firebase App Check and Google Play Integrity to help verify that requests originate from the authentic CenterStack application and to protect online services from abuse.
• Local game data:
Some game information is stored locally on the user's device, including settings, language preference, sound and vibration preferences, coins, achievements, statistics, themes, block patterns, daily mission progress, and similar gameplay progress.
2. How We Use Information
Information processed by CenterStack is used to:
• Provide player profiles and unique nicknames
• Provide weekly and all-time leaderboards
• Record and display game scores and rankings
• Provide leaderboard rewards
• Save gameplay progress and preferences
• Protect the game and its online services against abuse or unauthorized access
• Maintain and improve the operation and reliability of the game
3. Firebase and Google Services
CenterStack uses Google Firebase services, including:
• Firebase Authentication
• Cloud Firestore
• Cloud Functions
• Firebase App Check
CenterStack also uses Google Play Integrity as part of its application security system.
These services may process technical information required to provide authentication, database, cloud-function, security, and integrity-verification services.
4. Advertising and Sale of Personal Data
CenterStack does not currently display third-party advertisements.
AAAnnagur Apps does not sell users' personal data.
5. Data Sharing
CenterStack does not share player information with third parties for advertising or marketing purposes.
Information required for the operation and security of CenterStack may be processed by Google Firebase and Google Play services acting as infrastructure and service providers.
Leaderboard information such as player nicknames, scores, and rankings may be visible to other CenterStack players as part of the leaderboard feature.
6. Data Retention
Online player information is retained while the CenterStack account remains active and as necessary to operate the game's online features.
When an account deletion request is successfully completed, CenterStack deletes the account and associated online player data that can be linked to that account, subject to any information that must be retained where legally required.
7. Account and Data Deletion
Users can delete their CenterStack account directly from the application:
Settings → Delete Account
After confirmation, CenterStack deletes the anonymous Firebase account and associated player data handled by the account deletion system.
Users who cannot access the application may also request account and associated data deletion through the Account & Data Deletion page on this website.
8. Children's Privacy
CenterStack does not intentionally request a user's real name, email address, telephone number, or precise location as part of normal gameplay.
If we become aware that information has been collected in a way that requires deletion under applicable law, appropriate steps will be taken to remove it.
9. Security
CenterStack uses technical measures including Firebase Authentication, Firebase security mechanisms, Firebase App Check, and Google Play Integrity to help protect its online services.
No method of electronic transmission or storage can be guaranteed to be completely secure.
10. Changes to This Privacy Policy
This Privacy Policy may be updated when CenterStack features, services, or legal requirements change.
The latest version will be published on this page together with an updated revision date.
