⚠️ Important Disclaimer & External Services Notice

This application integrates external services including Firebase (for secure user authentication and optional database sync) and Google ML Kit (for offline/online OCR text recognition). Please note:

You will need to set up your own Firebase console account and generate your own Google services configuration files/API keys to use these features.
These third-party external services may incur additional costs depending on your production usage levels (Firebase provides a generous free tier under the Spark Plan, and Google ML Kit is free/offline for standard Latin and regional OCR APIs).
