It's not a question of having internet connectivity when you use the app, it's what permissions relative to your device you granted the app developers just by downloading the apps. Many people don't even look at what they are granting app developers access to from their phone/tablet. For example, I remember looking at a game app I was thinking about downloading that, had I done so, would have given them access to my SD card and photo gallery. Why does a game app need access to photos of my granddaughter or your children? I'm with UT, I look carefully at any app I'm considering.
