what information can apps from android app store get about me?

I'm not about to switch from goggle app store.

I just want to know what info the apps I install can get about me.

Can I stop random apps i install from the android app store from getting my phone number? If I use a random created account with goggle, can they see what other goggle accounts i have on the device?

What info will they get about me?

How do I keep them from getting personal info about me?
