Core Principle: LevinGPT is designed with privacy as a fundamental principle. All AI processing occurs on your device, and we do not collect or store your conversations on external servers.
Introduction
Welcome to LevinGPT ("we," "our," or "us"). We are committed to protecting your privacy and ensuring you understand how your data is handled. This Privacy Policy explains our practices regarding the collection, use, and disclosure of information through the LevinGPT mobile application (the "App").

How Your Data is Stored
Local Storage (On Your Device)
All your chat conversations, uploaded files, and app settings are stored locally on your device using Apple's SwiftData framework. This means:
- ✅ Your data stays on your iPhone
- ✅ We cannot access your conversations
- ✅ Your data is protected by your device's security (Face ID, passcode)
- ✅ Data is deleted when you delete the app
- ✅ No synchronization to cloud (no backups to external servers)
What This Means for You
- Privacy: Your conversations are completely private
- Security: Protected by iOS encryption and your device security
- Control: You can delete all data by uninstalling the app
- Limitation: Data doesn't sync across devices (intentional for privacy)
AI Processing
