Like other instant messaging tools, Skype too has a history feature through which it archives all the chats and call history, and stores them locally on your PC. If you want to erase this history, it can be done. It isn’t difficult to do it but the option may be difficult to locate.
You can look for all Skype conversations and call details by going to View->History. By default, Skype saves all your instant messages, SMS, calls, voicemails and file transfers. And it’s accessible to anyone who can get hold of your PC.
You could delete the previous chats and call details and disable the Skype history feature by changing the settings.
Go to Tools-> Options.
On left pane click on “Privacy settings” tab. Then, on the right, click on “Clear history” button.
A dialog box appears to confirm that you want to delete history. It shows you that all the recorded history will be deleted. Click on “Delete” button.
How to disable Skype history feature
