iFlowDiagram do not collect any kind of data or personal information from the user. The content created in the app (diagrams, images, etc.) is never collected. I just receive and get access to the feedback, when explicitly submitted by you. Your feedback is used to improve the quality of the app.
iFlowDiagram does not record your app usage in any way. The Apple app store may record the installation status of the app and geographical data.
If the app crash, i will receive information about the device model, iOS version and app version, which allows to identify problems to improve the performance of the app. This information is sent to me as added information that cannot be traced or used to identify a person.
