What will "Clear Data" erase in Facebook App

[samcraig]

My Facebook data is about 600mb - seems awfully high. I cleared the cache - but didn't want to clear data before finding out exactly what was stored there. I also have the messenger app installed.

So - does clear data delete messages from messenger? What else is stored in the FB data file?

I realize I will have to log back in with username/pw after deleting the data file. Just didn't want to delete something I would regret...

thanks for any help

It will clear most of its data, including your username and password. Ditch the app and use your browser instead.
