JustPaste.it was always focused on user's privacy.
Due to many requests from our users we've added new setting that allows you to hide counter with number of users that visited your note and those that are still online.
If you don't want other to be able to see how many people have read something, just select right option in "Access" tab while creating your note.
If you have registered on JustPaste.it you can set this option for all your note notes in Settings -> New notes.
You can also then check how many users visited the note on "Notes statistics" page.
