yaMPC accesses metadata of your music files through Music Player Daemon (MPD) and HTTP Server. Some of these data are cached in your iPhone or iPad but never sent to anywhere outside your iPhone/iPad. Therefore, we do not reuse such data for any purpose.
Apple Inc. provides us with some statistical information of yaMPC usage – such as number of crashes and number of downloading in each country. We use such information for user support, quality control and marketing promotion purposes only.
