## Summary by CodeRabbit

- **Bug Fixes**
- Enhanced user activity tracking by introducing airgapped environment
detection, preventing unnecessary tracking in restricted network
settings.
- **Tests**
- Added a new test suite to verify the behavior of the user activity
tracking method in airgapped conditions, ensuring correct functionality
based on the airgapped status.
