The Better Business Bureau says you need to do your homework before downloading the newest app. Whatever that app may be, you should check permissions you need to give it to operate, as BBB Investigator Don O’Brien says some will access your personal information if you let it.

Some apps will ask for your credit card information right off the bat, according to O’Brien, which could then allow them to hit your account without your permission. Other apps are more of a nuisance than a threat, hitting you with constant spam.
