Is it wise to install software like Aptoide?
I've seen it wants a lot of access rights.
Including permissions to private data.

Is there a way to find out, what the app wants with this data?
Is there a way to find out if the app has been changed by another person?

I guess you need "logging test app". It simply checks for your apps that are spying. I'm looking for it too.
