So I'm still looking for a decent media player to replace bTunes on my DInc since it appears the developer has abandoned the app. One of the apps I looked at was MixZing. I then found out that the app is sending some sort of information about my library back to their server. I don't know what information is being sent or why exactly so I figured I would ask. I presume it's sending information so it can generate recommendations for me, but if I turned that feature off I presume this player is just as private as any other player. But then I out this isn't the case and that it's still sending information to their server. So I ask them what information is being sent and for what purpose. I ask if I turn off recommendations do they still collect information and if so what information and for what purpose. To me this seems to be a fair enough question. If I'm supposed to pay $7 for an app that's going to collect information about me I should be entitled to know what info is being collected and why. I can then decide if the developer has a reasonable reason to collect said information and if I'm comfortable with them having it. The developer responds, "We track changes to your library (songs/playlists added/deleted) so that we can keep in sync with it." Now this makes no sense to me. Why does their server need to keep in sync with my library? It's not like I have access to my library from anywhere in the world through their server. So I ask again, "If I turn off music recommendations, does that information still get sent? If so, why?" I get this extremely pissy response from the developer that says, "As I said we need to keep track of your library so that we can perform the various functions of the player. If you don't want that information being sent to our server then just uninstall the app." I'm sorry, but the app is supposed to play music. You don't need to collect information for that. If they're collecting information so they can generate recommendations for other people, then why not just say that? The fact that the developer a) won't say exactly what information is being collected by this $7 app and b) won't say why they're collecting this information concerns me. Toss in that the developer gets pissy about it when you just ask what specific information is being collect and what it's being used for and I'm never going to use this app again. I like the app all other things being equal, but a $7 app that's collecting data about me and a developer who refuses to disclose what data is being collected and tells you to just uninstall the app if you don't like it pisses me off beyond belief. No one should ever buy this app. It basically spies on you and charges you for that privilege.
