This Privacy Policy describes how Physics AI Smart Solver ("we," "our," or "the App") collects, uses, and protects your information when you use our mobile application. We are committed to transparency and protecting your privacy.

1. Information We Collect

1.1 Information You Provide

Physics problems and images. When you use the App, you may:

Type or paste physics problem text into the text solver
