Once we install third party apps from the market, we are giving these developers a lot of personal information. Is it possible for a developer to create a program that collects sensitive data (e.g. bank account information, passwords, etc.) from our browsing experience even though the application is unrelated (maybe a flashlight, or sms app)? I am concerned as to how google is checking this with all these apps... Furthermore what if I download an app that doesn't come from the Market? Can a hacker edit the code for the original app and create their own app that collects your sensitive information?
