Thank you for using MMT. I know Privacy is important, so I would like to provide the following Information about Privacy and Security in MMT. As I am a German Citizen, I follow the German regulations on privacy called Bundes Datenschutzgesetzes (BDSG) des Telemediengesetzes (TMG) and others.
The App MMT is writing User Input into the Android System Log. Data like Input for an actual calculation is used for reproduction in case of a crash. MMT provides a Function to send those logs to the support unit. Only in that case will the data be read or analyzed.
Operations and Hosting of MMT is provided by LCube Webhosting. LCube is a German company and therefore LCube has to follow German Regulations on Privacy and Security. http://www.lcube-webhosting.de/
Depending on how Google Play is used, Google collects personal data. Some Data is provided to developers. I will save that data conforming to general German book-keeping regulations.
