Diffraction Limited Design, the owner of Vibration and Vibration Pro, takes user privacy very seriously. Vibration and Vibration Pro do not collect any data from users. All data that is saved by the app is saved locally to the app workspace on the device or to a cloud account of your choosing. If you decide to allow Apple to collect crash data and send it to the developer we will receive log files and crash dumps. These files will not contain any of your personal information.
