Block Bloom: Block Hub Privacy Policy
Effective September 19, 2026
Block Hub is provided by Koby Zada (“we”, “us”, or “our”). This policy explains the information processed when you use the app.
Information processed
Game progress, high scores, and settings are stored on your device. When you sign in with Google to play, Firebase Authentication processes your Google account identifier, display name, email address, and authentication state. Cloud Firestore stores your account-linked coin balance and leaderboard entries, including public display name, country flag, scores, and achievement dates. We do not receive your Google password.
To understand app usage, Firebase Analytics collects aggregate events such as first opens, sessions, and which games are launched. The app does not send your name or email to Analytics and disables advertising-ID collection by the Analytics SDK. After Google sign-in, a private, owner-accessible Firestore record also counts your hub opens, game launches, banner and rewarded-ad impressions and clicks, rewarded-ad starts and completions. This record includes your account identifier, email, display name, and last activity time. It is not a public leaderboard. These counters are approximate and begin only after the relevant app update and sign-in.
Google Mobile Ads and its advertising partners may process identifiers, IP address, app interactions, diagnostics, and approximate location derived from network information to provide, secure, measure, and, where permitted, personalise advertisements. Google Play processes purchases; we receive purchase status, product identifier, and a purchase token, but no full payment-card details.
Purposes and sharing
We use information to provide game features, leaderboards, purchases and ads; understand gameplay and app performance; prevent fraud; maintain security; and comply with law. Information may be processed by Firebase Authentication, Cloud Firestore, Firebase Analytics, Google Play Billing, and Google Mobile Ads. We do not sell personal information. The private player-activity report is visible only to the verified owner account; public leaderboards show the fields described above.
Data deletion
In the app, tap the Google account line, choose Delete app account, confirm, and select the signed-in account. You may also email kobyzada@gmail.com. The in-app process deletes the Firebase identity, wallet, Block Hub leaderboard entries, and private activity record. Local game data can be deleted by clearing app data or uninstalling. Google may retain transaction or analytics records according to its policies and legal requirements.
Children, security, and choices
The app is for a general audience and is not directed specifically to children under 13. Google sign-in is required to play Block Hub games. You may open the Hub before signing in, but cannot start a game without an account. The app does not request precise location, contacts, camera, microphone, or storage access. Rewarded ads are optional, and available advertising privacy controls can be used to decline personalised ads.
Contact and changes
For privacy requests, email kobyzada@gmail.com. We may update this policy; the effective date identifies the latest version.
