Mini Browser Platformer does not collect, store, or share any personal data. No accounts are required and no login information is saved.
The multiplayer feature uses Firebase Realtime Database (by Google) to synchronise player positions between players in the same level. The only data sent to Firebase is your player's X/Y position and current level number. This data is temporary: it is automatically deleted when you close the game. No names, identifiers, or personal information are stored. Each session uses a randomly generated anonymous ID that is not linked to you in any way.
This extension requests the tabs permission solely to open the fullscreen version of the game in a new browser tab when you click the fullscreen button. It does not read, access, or monitor any of your open tabs.
This extension uses Firebase Realtime Database (firebase.google.com) for multiplayer functionality. Please refer to Google's privacy policy at policies.google.com/privacy for more information.
If you have any questions about this privacy policy, you can reach out via the Chrome Web Store support page.
