Does the clipboard saves history by default in graphene, or it only saves the last content copied.
I have been using an app from fdroid to clear clipboard but if its the latter that means that I can just copy a new text if I want to overwrite sensitive data, eg passwords. The app does not drain battery bc it works only when I click it, but if graphene does not use history for clipboard then I might uninstall the app, it becomes redundant.
