This Privacy Policy explains how Blink Battle ("we", "our", or "the app") collects, uses, and protects your information when you use our mobile application.

1. Information We Collect

Camera: The app accesses your camera solely to detect blinks during gameplay using on-device ML processing. No video or images are recorded, stored, or transmitted to any server.
Account Information: If you sign in with Google or Facebook, we receive your display name and profile photo to create your in-app profile.
Usage Data: We collect anonymized analytics data (e.g., app crashes, session length) via Firebase Analytics and Firebase Crashlytics to improve performance.
Push Notifications: We may send push notifications via Firebase Cloud Messaging. You can disable these in your device settings at any time.
Purchase Information: Subscriptions are processed by Apple (App Store) or Google (Play Store). We receive only a purchase token to verify your subscription; we do not store payment card details.
