Android perimision "user's private information", "your personal information" , "read sensitive log data"

Well I found this texts on many applications, that is when I install some app the require the android.permission.READ_LOGS permission, they show some text like "permission for reading read sensitive log data..." the thing I do not understood is what this sensitive log data means ?

Does it means that it can read my passwords ? What is the data in this logs ? I googled but I couldn't开发者_JAVA百科 find anything , if you have some useful links it will be welcomed :-)

Thanks

"Logs" in this case primarily refers to LogCat, to which any application can log whatever it wishes.
