Bubblehead

Overview

Bubblehead is a free, ad-supported quiz game with an optional global leaderboard. This Privacy Policy explains what information is stored locally on your device and what limited data may be processed to support leaderboard functionality and advertising.

Leaderboard and anonymous sign-in

Bubblehead uses anonymous authentication to support the in-game leaderboard. When you choose a leaderboard display name, the following information may be stored securely using Firebase:

• Your chosen display name
• Your best score
• A randomly generated anonymous user ID
• Timestamps related to leaderboard activity

This information is used solely to display rankings and prevent duplicate records. No email address or personal identity information is collected.

Information stored on your device

• Local game data: your best score and certain gameplay settings are stored locally on your device using secure device storage.
• Leaderboard name: your chosen display name is stored locally so you do not need to re-enter it.

Advertising (Google AdMob)

Bubblehead displays ads provided by Google AdMob. The app is configured to request non‑personalised ads where applicable. Advertising providers may collect limited device information such as device identifiers, approximate location, and ad interaction data to serve ads, measure performance, and help prevent fraud.

In-app purchases

Bubblehead may offer optional in-app purchases (such as ad removal). Purchase transactions are processed securely by Apple or Google. We do not receive or store your payment details.

Data sharing

We do not sell your data. Leaderboard and authentication data are processed by Firebase, and advertising data is processed by Google AdMob, in accordance with their respective privacy policies.

Children’s privacy

Bubblehead is designed for a general audience. The app does not knowingly collect personal information such as names, email addresses, or precise location data. Ads are served in accordance with applicable platform policies.

Your choices

• You may uninstall the app at any time to remove locally stored data.
• You may choose not to participate in the leaderboard.

Changes to this policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated revision date.
