I want to ask whether it is safe to install an app from a high-risk provider. Googling has shown that Apple's app store does vetting of code to prevent stealing of information from personal information management (PIM) apps that are native to the iPhone, e.g., here and here.
The question is subjective, but I make it much more specific by describing the app provider's country of origin and it's attempts to hide that fact. I further make it more specific by stating the assumption of not being particularly targeted.
I have posted the question on reddit, but it isn't getting any attention, as it is not a security-oriented forum. Reddits mobile security forum doesn't seem to have seen activity in years and I do not get response to a request to participate (it is a restricted forum).
