:warning: Add user consent mechanism for data collection

Add user consent mechanism for data collection

The code collects user settings and host information without explicit user consent, which may violate privacy regulations (GDPR, CCPA).

Consider implementing:

1. A consent management system
2. Clear user notification about data collection
3. Option to opt-out of analytics
