Match 3 Battles • Last Updated: July 18, 2026

Your privacy is extremely important to us. This Privacy Policy explains how Match 3 Battles collects, uses, and safeguards information when you play our game.

1. Information We Collect

We collect minimal data to ensure a stable gaming session, persistent settings, and fair matchmaking features:

  • Local Game Progress: Your high scores, preferences (sound & hints), and level milestones are stored locally on your device via browser local storage.
  • Google Authentication: If you sign in using Google, we process your unique Google User ID, display name, and avatar picture to securely authenticate your account server-side.
  • Matchmaking Statistics: Scores, move history, and Elo ratings of your matches in the Multiplayer Arena are saved in our database to calculate ratings and support matchmaking.

2. How We Use Information

Any information gathered is used strictly for the following operational needs:

  • Creating and authenticating your player profile.
  • Matching you with appropriate opponents in the multiplayer arena based on your rating.
  • Displaying leaderboard rankings and profile setups.

3. Data Security & Third Parties

We do not sell, trade, or rent your personal identification information to third parties. All backend storage and matchmaking queues are managed on secured, cloud-native Firebase Firestore environments.

4. Cookies & Local Storage

We do not use any marketing, advertising, or tracking cookies. No third-party tracking scripts are loaded on this application.

We only use strictly necessary functional local storage items and session cookies (such as your game preferences, offline high scores, and secure Firebase authentication tokens) which are technically required to store your progress and securely deliver the matchmaking and game services you request. Because these storage components are strictly functional and necessary, they do not require a separate tracking opt-in cookie banner under EU/GDPR regulations.

5. Your Control

You can play entirely offline or as a local guest without signing in. If you want to request data deletion or have questions, please feel free to clear your local storage or sign out of your profile at any time.
