The Bird Data family of apps do not collect any personal information. No username, email or password is required. When images and sound files are downloaded from the server, only an IP address and time is recorded (as does virtually every web server), and this can not be connected to a specific device. Your usage of the app may be monitored by Apple depending on your phone settings (if you volunteered to help Apple). If you make a purchase, Apple will process the charge and provide the Bird Data app with verification, but not personal information. You can choose to share your location with the eBird Map, but your location is not saved by the app. You can record sound, but sound is only recorded when you initiate the recording with a button press, and stops when you stop the recording with a button press. Recordings are stored in internal storage, can not be shared, and are deleted when the application is deleted.
