1. LOCAL ARCHITECTURE (Local Storage)
This application uses your browser's local storage to save game state, including Quantum Coins, unlocked skins, UI preferences, and an anonymous generated ID (UUID). This data remains on your device unless linked to a cloud account or cleared by your browser.

2. GLOBAL LEADERBOARDS (Firebase)
If you submit a score, your chosen callsign, score, timestamp, and UUID are transmitted to our Firebase database to be displayed publicly on the Global Rankings and Hall of Legends. Callsigns are sanitized locally before transmission.

3. CLOUD BACKUP (Google Auth)
If you choose to link a Google Account, Firebase Authentication is used securely via Google's OAuth popup. We do not access your password. This links your local UUID to your Google UID to restore your save data across devices.

4. NETWORK TRANSMISSIONS (Google AdSense)
This site has Google AdSense infrastructure integrated for a planned, optional "Rewarded Transmission" feature (watch an ad for bonus coins). This feature is currently inactive and hidden from players while pending Google's review. Once active, third-party vendors, including Google, may use cookies to serve ads based on your prior visits to this or other websites.

Users may opt out of personalized advertising by visiting Google's Ads Settings.
