PrivacyZoneService class

Service for managing privacy zones and applying location obfuscation.

Privacy zones allow apps to define areas where location data should be protected. This supports GDPR and other privacy compliance requirements.

Example:

final service = PrivacyZoneService();

// Add a privacy zone around home
await service.addZone(PrivacyZone.create(
  identifier: 'home',
  latitude: 37.7749,
  longitude: -122.4194,
  radius: 100.0,
  action: PrivacyZoneAction.obfuscate,
));

// Process location through privacy filter
final result = service.processLocation(myLocation);
if (result.isUsable) {
  // Use result.processedLocation
}
