LostFound helps you create an image containing emergency contact information (in case you leave your phone at a restaurant or taxi cab, lose your phone, become injured, etc). Use this image as your lock screen's wallpaper.
LostFound does not collect any identifying information. If you have enabled crash reporting for all apps on your iOS device, the developer will receive anonymous crash reports to help improve the stability of the app. No specific information (such as contacts, entered phone numbers, email addresses, etc) are read or stored off of the device.
