Every app you want to install has its own permissions shown in very detailed form before installation. Never heard of full access permission- but is sounds very unlikely that an app will require this kind of approval, so avoid installing it.
If you still want to get risky, and you got android 4.3 and above. I suggest downloading 'App ops' from the market, which will let you control apps permission using google's privacy feature.
