Mobile apps created by Preflightsoftware are intended to run locally on your device without communicating with servers. The software will run in an unplugged environment, without network connections. Any data collected during the functioning of an app is only on your device and is not transmitted.
For any app that allows for archiving data to an external server, the archiving process requires an agreement between you and Preflightsoftware.
