If l would like to sell items on ebay that are NOT PICKUP, but must be posted,does the Buyer have my name and address ?

I do not like "strangers" coming to my house, l would not go to their house via ebay. A Garage Sale with signs out in the street, l feel is in a different scenario. 

As l only use PayPal for accepting payments, what information does PayPal give to my buyer ?  Do they the buyer, have access to any of my Financial Information ?  Would appreciate answers from the board members, thanx.
