For normal operation NKCCluster requires the following permissions:

PRECISE LOCATION (GPS AND NETWORK-BASED)
This permission is required for GPS Locator.

APPROXIMATE LOCATION (NETWORK-BASED)
Recommended for Google Maps API v2 (used in GPS Locator) but not actively in use.

FULL NETWORK ACCESS
This one is pretty self-explanatory, isn't it? Without network access NKCCluster wouldn't be of much use.

MODIFY OR DELETE THE CONTENTS OF YOUR USB STORAGE MODIFY OR DELETE THE CONTENTS OF YOUR SD CARD
Required for Google Maps API v2 (used in GPS Locator).

READ GOOGLE SERVICE CONFIGURATION
Required for Google services (Maps and Billing).

CONTROL VIBRATION
Required for spots' notifications.

VIEW NETWORK CONNECTIONS
Cluster nodes in general don't cope well with user sessions switching from one network to another (for example WiFi to 3G or vice-versa). This permission is required to detect when a network a device is connected to changes (or becomes unavailable) and take appropriate actions.

TEST ACCESS TO PROTECTED STORAGE TEST ACCESS TO PROTECTED STORAGE
Required for Google Maps API v2 (used in GPS Locator).
