Overview

Bubble Blend is a puzzle game developed by WobbleBot Studio. This privacy policy explains how we handle your data.

Children's Privacy (COPPA Compliance)

This app is designed to be safe for children and complies with the Children's Online Privacy Protection Act (COPPA):

• No behavioral tracking: We do not track children's behavior for advertising purposes
• Child-directed ads only: Advertisements are configured to show only age-appropriate content (G-rated)
• No personal data collection from children: We do not knowingly collect personal information from children under 13 without parental consent
• Optional features require action: Cloud sync and Google Sign-In are optional features that require explicit user action

GDPR Compliance (European Users)

For users in the European Economic Area (EEA), we comply with the General Data Protection Regulation (GDPR):

• Consent before ads: A consent form is displayed before showing personalized advertisements
• Right to refuse: You can refuse personalized ads; the app will still function with limited ads
• Right to deletion: You can delete all your data at any time (see "Your Rights" section below)
• Data portability: Your game progress is stored locally and can be synced to your Google account

Data Collection

Data stored locally on your device

• Game progress (current level, coins earned)
• Settings preferences (background, quality settings)

This data never leaves your device unless you explicitly enable cloud sync.

Local notifications

This app may send local notifications to remind you about game events. These notifications are processed entirely on your device and do not transmit any data to external servers. You can disable notifications in the app settings or your device settings at any time.

Data collected via Google Sign-In (optional)

If you choose to sign in with Google, we collect:

• Email address

This data is used solely to sync your game progress across devices via Firebase Firestore.

Advertising

This app displays ads via Google AdMob with the following privacy protections:

• COPPA compliance: Ads are tagged for child-directed treatment
• Content rating: Only G-rated (general audience) ads are shown

• Limited data collection: When consent is refused, only contextual (non-personalized) ads are shown

AdMob may collect:

• Device identifiers (Advertising ID) — only with consent
• IP address (for fraud prevention)
• General location (country-level)

You can opt out of personalized ads:

• In the app: Decline consent when prompted
